Abstract

Recycled Aggregate Concrete (RAC) has been recognized as concrete with lower performance compared to Natural Aggregate Concrete (NAC). Thus to improving the performance of RAC, the Micronised Biomass Silica (MBS) has been used as pozzolanic material. This paper discusses the impact of Micronized Biomass Silica, which is produced from rice husk ash in recycled aggregate concrete in terms of its compressive strength and water permeability. Various percentages of Micronised Biomass Silica have been used as pozzolanic material for producing RAC. The result shows that after 365 days, 12 % of Micronised Biomass Silica has the ability to enhance the performance of fully application of Recycled Aggregate in concrete for compressive strength up to 24 % and reduce the water permeability coefficient and water penetration up to 44 % and 22% respectively.
