Use of Sewage Sludge for the Substitution of Fine Aggregates for Concrete

Journal of Composites Science, 2023
This work analyzes the use of sewage sludge, generated in wastewater treatment plants, as an alternative for small aggregate to be used in concrete. Concrete cylindrical specimens with height h = 20 cm and diameter D = 10 cm were prepared using different amounts of sludge in the substitution of fine aggregates.

Feasibility study of compost as a partial substitute for fine aggregate in concrete [PDF]

International Review of Applied Sciences and Engineering, 2022
Abstract In this study, vermicompost is replaced for fine aggregate in geopolymer concrete (GPC). Initially mix design is made for GPC and mix proportion is proposed. The vermicompost is replaced at 5%, 10%, 15% and 20% with M sand in GPC.
