Abstract: | |
Excessive utilization of river sand as fine aggregates in building construction aggravates environmental degradation and urges the need for alternate source in the context of sustainable construction. This paper explores the feasibility of fly ash as fine aggregate replacement in the manufacture of concrete building blocks. An experimental investigation was carried out to evaluate the strength and durability characteristics of concrete building blocks by replacing fine aggregate (river sand) with fly ash. Test results indicate significant improvement in the strength properties of fly ash building blocks compared to conventional concrete building blocks. |
