Performance evaluation of Recron fibre and glass wool fibre reinforced self-compacting mortar at elevated temperature: A comparative study Anu Bala, Supratic Gupta, Vasant Matsagar Results in Engineering, 2025 The reinforcements of Recron fibre (RF) (0.2%, 0.4% and 0.6%) and glass wool fibre (GWF) (0.5%, 1% and 1.5%) have been evaluated for rheology, durability, compressive strength (CS) and flexural strength (FS) of self-compacting mortar (SCM) at different levels (0.43, 0.55 and 0.7) of effective water-to-cement ratio (w/c). The reinforcement of RF and GWF has resulted in negative impact on workability of SCM, and the highest yield stress of 232 MPa was obtained with reinforcement of RF of 0.6%, followed by yield stress of 162 MPa with reinforcement of GWF of 1.5% in SCM with w/c of 0.43. At 28 days of curing, the highest value of CS; 49.3 MPa was obtained for specimens having control mix with w/c of 0.43. The addition of fibres has decreased the CS but FS has increased with reinforcement of optimum fibre dosage. The lowest value of CS;15.7 MPa was obtained for SCM mix having w/c of 0.7 and RF of 0.6%, whereas the highest values of FS; 8.7 MPa was obtained for SCM (w/c of 0.43) with individual reinforcement of RF of 0.4% and GWF of 1.0%. The water permeability of SCMs was adversely affected by the increasing dosage of fibre reinforcements and w/c, but increasing dosage of RF and GWF has decreased the charge transfer rate through the SCM. The addition of RF and GWF has avoided the explosive spalling in SCM up to the heating temperature of 800°C, however, the explosive spalling has occurred at 600°C in control mix specimens. Compared to control mix design, the reinforcement of GWF has effectively controlled the strength loss in SCM, whereas, the addition of RF has improved the CS and FS with heating up to the temperature of 400°C. A steep decrement in CS and FS was observed with heating at 600°C and 800°C. Considering the rheology and properties of SCM at ambient and elevated temperatures, the optimal dosage of fibre reinforcement in SCM is recommended as; RF of 0.2-0.4% and GWF of 0.5%.
Concrete as a sustainable matrix for industrial waste fines: effects on water demand, strength, durability, and sustainability Pramendra Kumar, Supratic Gupta Journal of Sustainable Cement Based Materials, 2025 This study investigates the use of non-pozzolanic industrial fine powder waste, M-Sand fines powder (MsFP), marble fine powder (MFP), and granite fine powder (GFP) as a supplementary filler component in concrete. These industrial by-products, often disposed of in landfills, represent an underexplored resource for sustainable construction. In all, 49 concrete mix experiments were conducted, varying water-to-cement ratios (0.37–0.54) and fine powder contents of 100–400 kg/m³. The water correction factors of 3.20, 4.71, and 7.98 were established for MsFP, MFP, and GFP, respectively, assuring the effective w/c is comparable to the respective control concrete mix. Results showed similar compressive strength to control mixes, with improved water penetration resistance due to pore size refinement, as confirmed by two different water permeability tests and further confirmation by scanning electron microscopy analysis. Sustainability assessment indicated reduced embodied energy and CO2 emissions, while cost analysis revealed economic advantages. The findings demonstrate that fine powder incorporation enhances concrete durability and promotes sustainable construction by reducing industrial waste and conserving natural resources.
Durability and Cost Analysis of High-Volume Fly Ash Blended Self-Compacting Mortar Anu Bala, Kunal Shelote, Supratic Gupta Journal of Materials in Civil Engineering, 2024 In the present study, the effect of high-volume fly ash blending in the concentration of 15%, 25%, 35%, 45%, and 55% with different effective water-to-cement (W/C) ratios has been investigated for rheology, compressive strength (CS), and durability of self-compacting mortar (SC-mortar). The rheology of SC-mortar was evaluated in terms of slump flow diameter, v-funnel flow time, and developed yield stress and plastic viscosity. The CS of SC-mortar was evaluated at 7 and 28 days of curing, whereas the water permeability and rapid chloride penetration tests were performed to evaluate the durability of SC-mortar at 28, 90, and 180 days. The consumption of ordinary portland cement was reduced using the k-factor or cementing efficiency factor in mix design, where the value of the k-factor decreases with increasing fly ash content. The experimental study revealed that the addition of a high volume of fly ash has a significant impact on rheology and durability, whereas CS of SC-mortar was affected marginally. Scanning electron microscopic (SEM) examination revealed that the fly ash blending has improved the packing and reduced the pore density to compensate for the loss of CS on account of lower cement content. An increase in W/C has increased the porosity, causing a negative impact on CS and durability. The durability of SC-mortar has increased with increasing fly ash content, and there was an exceptional increment in water ingression time (T25) with an increase in fly ash content from 25% to 35%, but with higher content of fly ash (above 35%) and low value of W/C, SC-mortar become very sticky, thus reduced the workability significantly. Compared with the control mix, there is a significant reduction in the cost of SC-mortar with fly ash blending of 15%, thereafter, the cost reduction is marginal with a further increase in fly ash dosage which is due to the rise in admixture dosage. Based on the rheology (within EFNARC limits), CS, and durability of SC-mortar, the optimized dosage of fly ash has been recommended in the range of 25%–40% with different W/C.
