Enhancing the Sustainability of Concrete by Adding Recycled Sand and Silica Fume Along with Human Hair Fibers

Journal of Composites Science, Journal Year: 2025, Volume and Issue: 9(5), P. 216 - 216

Published: April 29, 2025

This experimental study produced recycled sand–silica fume–hair fiber concrete to enhance sustainability. Recycled sand and silica fume can be used address the environmental issues caused by excessive river mining carbon footprint of industry. In addition, waste hair fibers (0.5–2%) were introduced properties newly developed mixes. The absolute volume method was employed for four sustainable A 100 mm slump set as a structural requirement, which maintained adding 0.5%, 1%, 1.4%, 1.9%, 2.6% admixture weight cement proposed compressive strength, splitting tensile density hardened mixtures estimated. results show that combining optimized 10% with 0.5–2% enhanced threshold met when 1.5% mixed fume, 50% manufactured sand, sand. However, strengths mixes 2.0% found almost same at 5.62 MPa 5.65 MPa, respectively. bulk increased increasing percentages fibers. Furthermore, in fibers, very similar 2.708 g/cm3 2.792 g/cm3, Thus, it concluded from containing optimal is acceptable concrete.

Use of Biomass Bottom Ash as an Alternative Solution to Natural Aggregates in Concrete Applications: A Review

Materials, Journal Year: 2024, Volume and Issue: 17(18), P. 4504 - 4504

Published: Sept. 13, 2024

Biomass bottom ash (BBA) is a by-product of the energy industry and produced from biomass-fired thermal power plants. They represent coarsest fraction recovered are mostly landfilled. Several researchers have investigated feasibility use BBA as replacement for natural aggregates in cementitious material. The utilisation manufacturing concrete provides an economic ecological way to upcycle it. At same time, its conserves resources promotes sustainability. This review article first presents chemical, mineralogical physical properties BBA, highlight possible effects on materials interest valorising them building Secondly, focus incorporated place used concrete. investigates multi-physical manufactured with partial incorporation BBA. substitution leads decreased workability, which can be limited by admixtures. In hardened state, reduction mechanical shown replacement. However, many experimental works show that appropriate proportions maintain specified

Study on Freeze–Thaw Resistance of Cement Concrete with Manufactured Sand Based on BP Neural Network

Buildings, Journal Year: 2024, Volume and Issue: 14(9), P. 2952 - 2952

Published: Sept. 19, 2024

In this study, experiments were conducted on the freeze–thaw performance of manufactured sand cement concrete with different ratios and fly ash contents. The research found that during 200 cycles, as content increased, exhibited a higher mass loss rate decline in relative dynamic modulus elasticity. This was due to lower activity SiO2 Al2O3 ash, which reduced hydration products. Incorporating an optimal amount can increase density concrete, thereby improving its resistance cycles. However, when high, large surface area could interfere process reduce strength, diminishing concrete. Given studying is time-consuming influenced by many factors, prediction model based BP (back propagation) neural network developed estimate elasticity following After validation, be highly reliable serve foundation for mix design decisions
