Experimental Investigation on the Influence of Micronized Biomass Silica in the Recycled Aggregate Concrete



The use of recycled aggregate concrete in structural application is restricted due to the high strength reduction and higher water absorption. In this study, Micronized biomass silica (MBS) a pozzolanic material produced from rice husk was used as a partial replacement of cement to improve the performance of the recycled aggregate concrete. Recycled aggregate concrete with and without MBS has been investigated and the results of the mechanical and durability properties such as compressive strength, split tensile strength, flexural strength, rapid chloride permeability and water absorption were compared with conventional concrete. The test results showed that recycled aggregate concrete without MBS was inferior to conventional concrete but with MBS showed similar results like conventional concrete. Thus, the drawbacks in the use of recycled aggregates in concrete for structural application can be overcome by using MBS as cement replacing material.
