  • Feasibility of incorporating biopolymer-stabilized chromium-contaminated soil as fine aggregate in concrete

    Heavy metal pollution due to fast industrialization causes severe threats to water bodies and the soil environment. Remediating chromium‐contaminated soil using conventional chemical, physical and biological methods is highly tedious, especially when a site is contaminated on a large scale. The present study explores the solidification and stabilization of chromium‐contaminated soil using a waste‐derived chitosan biopolymeric composite. Further, chitosan‐stabilized soil was utilized for the preparation of M25 concrete cubes. The results revealed that the compressive strength of the concrete cubes prepared with chromium‐contaminated soil and biopolymeric composite showed a 40% increment in strength at 20% replacement of solidified soil (by weight) compared to the pristine concrete cubes. The incorporation of chitosan in the chromium‐contaminated soil enhanced the binding within the concrete matrix, contributing to improved compressive strength. The toxicity characteristics leaching procedure (TCLP) studies of the concrete cubes prepared with the stabilized soil showed that the chromium concentration released from the cubes is negligible, which is 99% lesser than the chromium leached from the cubes prepared using unstabilized chromium‐contaminated soil. Further, this study highlights the potential for utilizing contaminated soil in concrete applications, thereby supporting circular economy principles; however, a comprehensive life cycle and cost assessment is required to fully evaluate its environmental and economic feasibility.

    <p>Divination and determination of catchment surface runoff are the most important contestable process of hydrology. Soil Conservation Service - Curve Number (SCS – CN) method is employed to estimate the runoff. It is one of the physical based and spatially distributed hydrological models. In this model, the curve number is a primary factor used for runoff calculation. The selection of curve number is based on the land use pattern and HSG (Hydrological Soil Group) present in the study area. Since the spatial distribution of CN estimation by the conventional way is very difficult and time consuming, the GIS (Geographic Information System) based CN method is generated for Kundapallam watershed. With the combination of land use and HSG the estimated composite CN for AMC (Antecedent Moisture Condition) I, AMC II and AMC III for the entire watershed was about 48, 68 and 83 respectively. The average annual runoff depth estimated by SCS-CN method for the average annual rainfall of 173.5 mm was found to be 72.5 mm. The obtained results were comparable to measured runoff in the watershed.</p><p> </p><p><strong>Resumen</strong></p>La predicción y la determinación del caudal de escorrentía de una cuenca son procesos de amplio debate en la hidrología. El método coeficiente de escurrimiento, del Servicio de Conservación de Suelos (SCS-CN, inglés) fue utilizado en este trabajo para estimar la escorrentía. Este es uno de los modelos hidrológicos basados en conceptos físicos y distribución espacial. En este modelo el coeficiente de escurrimiento es un factor de relevancia para el cálculo de la escorrentía. La selección del coeficiente de escurrimiento está basada en los patrones del uso de la tierra y del Grupo de Suelos Hidrológicos (HSG, inglés) relativos a esta área de estudio. Debido a que la estimación del coeficiente de escurrimiento en la distribución espacial es compleja, para la cuenca Kundapallam se implementó un método a partir de un Sistema de Información Geográfica (GIS, inglés), y basado en el coeficiente de escurrimiento. Con la combinación del uso de suelos y el HSG, la estimación compuesta del coeficiente de escurrimiento para el Antecedente de Condición de Humedad AMCI, AMCII y AMCIII para toda la cuenca fue de 48, 68 y 83. El promedio anual de escorrentía profunda estimada por el método SCS-CN con una media anual de lluvia de 173,5 mm fue de 72,5 mm. Los resultados fueron comparados con la escorrentía medida en la cuenca.

  • Studies on strength and behaviors of concrete by using pond ash as fine aggregate

    Common river sand is expensive due to excessive cost of transportation from natural resources. Also large scale depletion of these sources creates environmental problems. In such a situation the pond ash can be an economical alternative to the river sand. Pond ash can be defined as residue and by-product of thermal power plant stations to form fine particles less than 4.75 mm. Usually, Pond ash is used in a large scale for manufacturing of bricks. Use of pond ash as a fine aggregate in concrete mortar draws serious attention of researchers. This study reports the results of some experimental studies on the use of pond ash as Fine Aggregate (FA) in concrete. Super plasticiser is used to increase the workability of concrete with lower water cement ratio. The percentage of pond ash added by weight was 0, 20, 30, 40 and 50, respectively as replacement of FA used in concrete. Experiments were carried out to determine the compressive, splitting tensile and flexural strength with those of conventional concrete made with pond ash as fine aggregate. The various mechanical properties were studied and compared with natural fine aggregate. The test results obtained indicate that pond ash of marginal quantity as partial sand replacement has beneficial effect on the mechanical properties. The strength development for various percentages (0-50%) replacement of fine aggregate with pond ash can easily be equated to the strength development of normal concrete with various ages. The properties of aggregates were also compared. Test result indicates that the workability of pond ash concrete is good and the strength characteristics are comparable to those of conventional concrete.
