Abstract
The quest for sustainable construction materials is rapidly increasing; due to health hazards associated the traditional construction items. This research goal is to investigate how sugarcane bagasse ash (SBA), crushed periwinkle shells (CPS) and cassava starch (CS) incursion affects
the engineering performance of sandcrete blocks, and the physiochemical qualities of their leachate. SBA was incorporated at a rate of 5, 10, 15 and 20% as substitution for cement; treated CPS (TCPS) and untreated CPS (UCPS) were add at a rate of 10, 15, 20 and 25% as partial replacement for
sand; while 1% CS was added as integrity enhancer. A consistent cement–sand mix ratio of 1:8 and corresponding water–cement (w/c) ratio of 0.55 were employed across all 17 experimental units; and the blocks were cured using the irrigation technique. Likewise, the blocks were subjected
to leaching condition (immersion in water) to collect their leachate. Chemical compositions of the SBA, sand, cement, CS and TCPS and UCPS were examined using the x–ray fluorescent technique, while the mechanical and physiochemical parameters of the blocks were studied in harmony with
the American Society for Testing and Materials standards. The results obtained revealed that the mechanical and physiochemical qualities of the blocks were dependent on the volume of the bio–materials incorporated into the sandcrete. Furthermore, the findings showed that an environmentally
friendly high–strength lightweight sandcrete blocks, meeting international requirement of 3.45 N/mm2 can be produced by incorporating 10% SBA, 15% TCPS and 1% CS into the sandcrete block. The research highlights the possibility of using agricultural waste materials in achieving
sustainable materials for the housing industry.
