ABSTRACT:
Cement manufacturing now generates a lot of carbon dioxide (CO2), therefore finding environmentally acceptable, long-lasting alternatives to cement as a binder is becoming increasingly important. The purpose of this investigation was to examine the effects of adding rice husk ash (RHA) as a supplemental cementitious material on the compressive and flexural strengths of concrete. RHA's pozzolanic nature makes it a promising alternative binder, but it can only partially replace cement up to a certain percentage; beyond that, the concrete's strength drops, making it less desirable. Thus, Polypropylene (PP) fibers were employed to reinforce RHA-based eco-friendly concrete. After analyzing the data, it was found that while 5% RHA was stronger than the control sample, increasing the RHA level beyond that point significantly reduced the strength. When PP fibres were added to concrete that had 10% RHA and had decreased strength, the concrete's strength increased.
