| Summary: | Utilization of Recycled Aggregate (RA) in concrete is due to the awareness of society in preserving natural resources for future generation. RA application as coarse aggregate in concrete mixes initiation is to make use effectively of the waste materials. The purpose of this study is to improve the Recycled Aggregate Concrete (RAC) by using the Micronized Biomass Silica (MBS). Concrete cube specimens containing various percentages of RA and MBS were prepared and tested. The results indicated that after 28 days curing, concrete containing 12 % of MBS and 100% RA enables to enhance the compressive strength up to 17.20 % and reduce the water permeability coefficient and water penetration up to 47.10 % and 7.5 % respectively. It can be concluded that RAC containing MBS perform significantly better RAC without MBS. |
