Rice Hull Ash Concrete Mechanical Properties

Abstract:

This technical note discusses an innovative use of rice hull ash (RHS) as filler in concrete. RHS in the range of 0–30% was used as a partial replacement for ordinary cement in a concrete of mix ratio 1:2:4:0.6 (cement: sand: coarse aggregate: water cement ratio). Fresh concrete properties, compressive, split tensile strengths, and modulus of rupture were measured for concrete mixtures with RHS within the investigated replacement levels. The results showed that the setting times of RSH concrete increased with higher ash content, while the compressive, split tensile strengths and modulus of rupture showed a reverse trend.
