  • Experimental Investigations of stabilization of Black cotton soil
    H K Abharan, Harish Acharya, and M Manjunatha
    IOP Publishing
    Abstract The technique of stabilizing soil aids in achieving the qualities of soil that are necessary for building projects. Black cotton soils, sometimes referred to as swelling soils, are those soil types that have a propensity to expand and contract in response to changes in moisture content. By increasing the strength of the black cotton soil, this experimental investigation on stabilizing the soil with a certain amount of granite dust produces positive results. The maximum dry density and reduced potential for shrinkage and swelling are found in the black cotton soil mixed with 5% granite. The greatest results are obtained with 10% of the granite mix with black cotton soil since this experiment shows a significant decrease in the ideal moisture content.

    The availability of productive land is significantly impacted by the global phenomenon of urbanization. The amount of land available for food production and other essential activities decreases as cities grow because the urban perimeter encroaches on rural and natural areas. Conducting research on urban sprawl analysis and land use land cover (LULC) change assessment is essential in ensuring sustainable urban growth. Bengaluru, a rapidly expanding metropolitan city, has a significant impact on the area around it, making it a prime location for this kind of study. In this study, authors sought to assess how urban sprawl affected LULC in the Bengaluru rural district that surrounds the city of Bengaluru. The study evaluated changes in LULC over a two-decade period using remote sensing data and GIS tools. Five LULC classes were used to categorize the study area: settlement, waterbody, vegetation, agriculture, and barren land. The maximum likelihood technique was used to classify Landsat images from three different time periods using the supervised image classification method in the ERDAS software. Accuracy assessment was used to gauge the classified images’ accuracy. The study’s important findings showed how the LULC classes in the study area have been negatively impacted by the urban sprawl. The study emphasizes the significance of ongoing research in LULC change assessment and urban sprawl analysis to ensure sustainable urban growth and safeguard the availability of productive land.

    Hindawi Limited
    Use of bricks and their manufacturing process plays an important role in the construction sector. Despite its various methods of manufacturing, still large quantities of bricks are used in the building construction. Manufacturing of bricks consumes large quantities of natural resources, and it is energy intensive. Similarly, due to rapid industrialization large quantities of waste industrial byproducts are generated and causes handling and disposal challenges of these wastes. This review work attempts the possibilities and potential use of various types of waste industrial byproducts in fired and unfired bricks. This study also highlights the importance of waste and its usage guidelines in bricks manufacturing to enhance the strength and durability properties. To overcome the challenges associated with bricks manufacturing, firing is still considered as the most preferred method of making bricks. Use of industrial waste byproducts to the mix matrix of fire and unfired bricks will overcome the disposal challenges and reduce the depletion of natural resources. Since sustainability is a key factor that is considered when it comes to making bricks, innovative methods are needed to produce them using sustainable materials. The production and application of bricks and their usage guidelines are reviewed further in various aspects such as environment, social, economic, and technology to meet global standards and policies of the local government for sustainable development.

    Hindawi Limited
    Stone mastic asphalt (SMA) mix amended with sugarcane bagasse fibers (SBFs) as a stabilizer was investigated experimentally in the present study. The SBF content in the combination mix was varied (0, 0.15%, 0.30%, 0.45% and 0.60%) to produce different mixtures. The prepared mixtures were then assessed for different properties, such as the Marshall stability, tensile strength, and draindown, which are crucial for the performance of the mix in flexible/bituminous pavements. The experimental results revealed enhanced stability and flow value, greater filling of voids in the bitumen, and reduced air voids in the prepared SMA mix amended with SBF. In addition, improvement in the tensile strength of the SMA mix amended with SBF was observed. An increase in the tensile strength ratio of the amended SMA mix was also observed. The susceptibility to the entry of moisture into the pores of the SMA mix was assessed by performing the draindown test, which revealed that the amended SMA mix exhibited reduced draindown due to the presence of SBF. Therefore, it was inferred that the inclusion of SBF into the SMA mix was beneficial for enhancing the stability and tensile strength of the mix and achieving higher resistance to moisture penetration. The present study demonstrated that the use of sugarcane bagasse as an active ingredient in the SMA mix would result in improved performance of flexible pavements while also reducing the waste burden of landfills and aiding in effective waste management.

    Technoscience Publications
    Hesaraghatta watershed is one of the most vital and environmentally substantial watersheds in the Arkavathi basin. It has a freshwater lake created in the year 1894 across the Arkavathi River to quench the drinking water requirements of Bengaluru city. The watershed is facing significant stresses due to rapid urbanization and other developmental activities. For this study, an attempt is made to assess the distribution of various land use land cover classes and their temporal changes over 18 years using remote sensed data and GIS tools. The watershed is categorized into four land use land cover classifications: settlement, waterbody, vegetation, and bare soil. The maximum likelihood technique is utilized for the image classification and accuracy assessment is carried out to evaluate the accuracy of image classification. The outcome of the study revealed that there is a substantial change in land use land cover classes in the Hesaraghatta watershed.

  • Drainage morphometry based sub-watershed prioritization of Kalinadi basin using geospatial technology
    A Bharath, K Kiran Kumar, Ramesh Maddamsetty, M Manjunatha, Ranjitha B Tangadagi, and S Preethi
    Elsevier BV
    ABSTRACT Watershed management is an essential part to achieve sustainability. In the case of large watersheds, management and conservation practices cannot be implemented efficiently over the entire area due to inadequate human resources and financial support. Therefore, prioritizing the sub-watersheds and implementation of management practices would be a viable technique to ensure sustainability within the watershed. In this study, sub-watershed prioritization is carried out for the Kalinadi basin based on erosion susceptibility using morphometric analysis. SRTM DEM is used to extract stream network and delineate the sub-watersheds using ArcGIS software. Further, the Kalinadi basin is divided into eight sub-watersheds and morphometric analysis performed. In the current study, for prioritizing the sub-watersheds, nineteen morphometric parameters are considered which include linear, aerial and relief aspects. The results of linear, aerial and relief parameters of every sub-watershed are given with ranks based on their influence on soil erosion and then subjected to compound parameter analysis which is used to prioritize each sub-watershed. The morphometry-based prioritization findings demonstrate that Sub watershed-8 (SW-8), SW-4 and SW-5 face high risk, SW-6, SW-7 and SW-2 face medium risk whereas SW-3 and SW-1 face a low risk of soil erosion. The results can be used by the decision-making authorities to plan and implement the watershed management practices optimally to control soil erosion.

    Journal of Engineering Research
    To meet the intensifying demand of fine aggregate in construction sector, manufactured sand has become a viable alternative to the river sand. Ready mix concrete (RMC) is playing vital role in fast-track construction particularly in Tire-II cities in India. The strength and durability concerns about using 100% manufactured sand along with mineral admixtures in RMC plant needs to be addressed through suitable experimental demonstrations. This research gives the experimental results on strength and durability studies of concrete carried out on samples obtained from RMC Plant by making use of manufactured sand containing (50% of crushed sand and 50% of the crushed rock fines) as replacement for natural sand. Trials on partial replacing cement with fly ash content of 33% and GGBS of 40% has also been carried out. Compressive and split-tensile strength studies were conducted on cubes (150mmx150mmx150mm) and cylinders (150mmx300mm) at 7, 14 &amp; 28 days of curing. Non-Destructive tests such as Ultra Sonic Pulse Velocity (UPV) and rebound hammer tests were conducted to assess the quality of these mixes. Durability tests were conducted and comparison of the % of loss in mass and % of loss in strength for concrete samples subjected to acid attack, sulphate attack, alkaline attack tests were also carried out. Rapid chloride permeability test (RCPT) was conducted to check the concrete resistance against chloride ions penetration. The experimental results revealed that the use of 100% manufactured sand along with mineral admixtures in producing ready mix concrete is a good choice in view of the non-availability of river sand to meet the demands of fast-track construction projects.

    Abstract This study reports the experimental investigation about the performance of fly ash and untreated waste foundry sand on fresh and hardened state of concrete mix. In this research, 30% fly ash is kept constant as a partial replacement of cement and Natural river sand is replaced with waste foundry sand (WFS) in varying percentages (0%, 10%, 20%, 30% and 40%) for M40 grade concrete. Compaction factor test and slump cone test is conducted to assess the fresh properties of concrete. Similarly, Compressive, split tensile and flexural strength tests are conducted to evaluate the mechanical properties of concrete as per Indian standard. This investigation also covers ultrasonic pulse velocity test to assess the quality of hardened concrete at 7, 14, 28, and 90 days curing period. Based on investigation, test results indicate that use of WFS as a partial replacement of sand in concrete improves the mechanical and fresh properties of concrete up to 30% replacement. Thereafter a marginal decrease in strength is noticed for 40% replacement level. Similarly, the mixes containing 30% WFS exhibits better quality when compared to reference mix having 0% waste foundry sand. As a sustainable approach, use of WFS up to 30% have a greater impact on reducing cost of construction and makes concrete eco-friendly.

  • Role of engineered fibers on fresh and mechanical properties of concrete prepared with GGBS and PVC waste powder - An experimental study
    M. Manjunatha, Dinesh Seth, and K.V.G.D. Balaji
    Elsevier BV
    Abstract This research reports the experimental investigation, capturing the effect of engineered fibers on fresh and mechanical properties of M50 grade concrete blended with poly-vinyl chloride (PVC) waste powder with one mineral admixture and one chemical admixture as superplasticizer. In this experimental investigation fourteen mixes (seven mixes with fibers and seven mixes without fibers) are prepared using ground granulated blast furnace slag (GGBS) as mineral admixture and PVC waste powder. In these mixes PVC waste powder content is varied in 0% (treated as reference mix), 5%, 10%, 15%, 20%, 25% and 30% by weight of cement whereas, 30% of GGBS is kept constant except reference mix. 0.6% of sulpho-naphthalene formaldehyde (SNF) as superplasticizer, by weight of cement are kept constant in all the mixes. Similarly, to study the effect of fibers on fresh and mechanical properties of concrete, 0.5% of engineered fibers are used along with 0.6% of superplasticizer. So that a comparison between with and without fibers could be prepared. Fresh properties of concrete are studied by using slump and compaction factor test for all the mixes. Similarly, the prepared test specimens are tested for the mechanical properties like compressive, flexural and split tensile strength as per Indian standard IS:516-1959 at 7, 14, 28and 90-days curing period. Test results indicates that up to 20% PVC waste powder can be used as a partial replacement of cement along with 30% GGBS, 0.6% of SNF superplasticizer, and 0.5% fibers in M50 grade concrete without compromising strength properties. Use of engineered fibers along with GGBS and PVC waste powder not only helps in reducing the cement consumption, but also improves strength properties and facilitates in lowering the cost of construction.

    Abstract The Construction industry consumes a large amount of natural resources and energy. It is one of the main sources of waste generation and greenhouse gas emissions (GHG). The preparation and utilization of concrete have a great impact on climate change and environmental pollution. Environmental impact assessment of concrete is of prodigious importance in terms of accomplishing a sustainable society. Cement is a commonly used binding material for the preparation of concrete. The manufacture and utilization of cement in concrete are main responsible for GHG emission and climate change. In this research, to measure the environmental impact of concrete, the Life cycle assessment (LCA) model is prepared by using SimaPro 9.1 software and Ecoinvent database. Concrete is prepared with three different categories of binding materials like Portland cement (OPC), ground granulated blast furnace slag (GGBS) and portland pozzolana cement (PPC). Results indicate that, PPC and GGBS have greater impact on environment when compared to OPC.

    Elsevier BV
    Abstract Preparation of subgrade plays an significant role in construction of roads as it acts as the foundation to the flexible pavement. The soil subgrade can be utilized to its full extent only if it is well compacted, the subgrade strength is related to the CBR of soil. Determination of stiffness modulus and shear strength of the subgrade using California bearing ratio (CBR) test. The CBR values be contingent on the nature & other properties of soil. CBR test is very laborious, time overwhelming & always be performed on moulded soil samples which makes it difficult to get accurate values and also to implement in reality. In the present study the authors have made an attempt to calculate the CBR values and the index properties of the soil and to develop a relationship between them so that one can obtain reliable CBR values in less time. The authors have collected the samples from Chickballapur district, India and correlated unsoaked and soaked CBR value with maximum dry density, optimum moisture content, percentage fines, liquid limit and unconfined compressive strength etc. Experimental outcomes indicates that the soil properties influence the CBR value of soil. Correlations are developed between the California bearing ratio and maximum dry density with satisfactory R2 values with which CBR values can be predicted.

    Elsevier BV
    Abstract Natural fibers have grown extensively during the last few years and have become interesting to scientists and researchers as an alternative preference for wood dust fiber composites. As they have good mechanical properties, cost adequacy, non-abrasiveness, high particular quality, eco-accommodating, and biodegradability features. They are abused as a trade for traditional fibers like carbon and glass. In present correspondence, the study on the preparation and characterization of a new arrangement of green composites, including Tectona Grandis wood flour fiber as a strengthening material in polymer grid based on epoxy resin has been accounted. The stable mechanical properties of erratically orientated personally blended Tectona Grandis wood flour fiber-reinforced polymer green composites such as tensile, compression, and hardness properties were explored as a purpose of fiber loading. The reinforcement of resin with Tectona Grandis wood dust fiber is accomplished in particulate fiber by employing optimized resin. These fibers were blended with epoxy resin in diverse fortification strengthening percentages. The outcome of the above said mechanical properties were measured. It has demonstrated a development in these stable mechanical properties after reinforcement by fibers. The estimation of static mechanical properties will increment in an increasing percentage of reinforcement. The average ultimate tensile strength is 17.50 MPa, and the compression strength is 246.93 MPa. The microstructural behavior of these composites is studied with the help of scanning electron microscopy (SEM), and the moisture absorption test is also carried out.

  • The sustainable use of waste copper slag in concrete: An experimental research
    M. Manjunatha, T.V. Reshma, K.V.G.D. Balaji, A. Bharath, and Ranjitha B. Tangadagi
    Elsevier BV
    Abstract Industrialization is blossoming gradually and has uplifted the living standard of human beings. Now it became hazardous to environment, because of disposal challenges due to waste by-products. Manufacturing of copper-based products consumes natural resources, energy, it emits various greenhouse gasses to the environment and causes natural depletion. Whereas, construction industry consumes natural resources like, river sand, aggregate, wood, lime and clay to manufacture cement to name a few on a wide scale to build infrastructure. In this research, to reduce the resource consumption, to overcome the environmental challenges due to waste by-products, authors used waste copper slag. Authors attempted use of waste copper slag (WCS) as a substitute for river sand in M40 grade concrete. Similarly, poly propylene fibres (PPF) are used to study the effect of fibres on concrete prepared with WCS. This research concentrates on mechanical and fresh properties of concrete prepared with and without PPF on use of WCS as a partial replacement of river sand. Experimental findings indicate that, use of WCS improves the fresh properties of concrete linearly. Also, mechanical properties of concrete prepared with up to 60% WCS by weight of sand enhances strengths of concrete in marginal rate. Use of WCS as a substitute for river sand, helps in reducing the cost of concrete preparation and consumption of natural resources. This research helps researchers and practitioners in making concrete sustainable and eco-friendly by using WCS.

    Association of Computer, Communication and Education for National Triumph Social and Welfare Society (ACCENTS)
    Energy computations in commercial and residential buildings have been studied over the past few years by various researchers. The studies have revealed an interesting relation between the materials used in the building, the manufacturing process, the construction process, and its overall impact on the environment. However, limited studies have been conducted on the computation of the Embodied Energy (EE) and the Operational Energy (OE) of residential buildings. In the present investigation, an attempt has been made to compute these two factors (EE and OE) for a residential building situated in Vijayawada, Andhra Pradesh, India. The case study chosen here is an exciting example of a reinforced cement concrete framed structure with ground + three floors. Based on the conducted studies, the EE computations show that a huge amount of energy is used for materials such as cement, steel, and bricks. The use of alternative building materials to these and technologies can help in reducing EE. OE can be reduced during the lifetime of the building by implementing different methods of energy conservation. The energy consumption in a typical residential building depends on the types of appliances, usage hours, the consumption of the devices, etc. Changes in any one of these could alter the annual energy consumption, and thus, the OE. The EE content is experienced once separately from maintenance and renovation, whereas OE gathers over time and can be prejudiced throughout the life of the structure.
