MBS as a Potential Cement Replacement Material in Recycled Aggregate Concrete

Recycled Aggregate Concrete (RAC) was known as concrete which used partly or fully waste material as coarse or fine aggregate. This concrete was identified to have a lower compressive strength than Normal Aggregate Concrete (NAC). As alternative, Micronised Biomass Silica (MBS) was applied as cement replacement material in concrete mixes. This is as an effort to increase the compressive strength of RAC. For this study, MBS was used at 0%, 4%, 8% and 12% was used as cement replacement material. Meanwhile, Recycled Aggregate (RA) from waste cube concrete was used to replace a normal aggregate as coarse aggregate at various percentages (0%, 25%, 50%, 75% and 100%). The results showed that compressive strength of the RAC at all ages were lower than control concrete. Also, it was found that RAC that contains MBS attained higher compressive strength than RAC with 0% MBS
