This research was conducted to determine the effect of adding the rice husk ash (RHA) from mechano-chemical process as cement replacement for concrete. Mechano-chemical process was carried out using planetary ball mill with the rational speed at 22 rpm for 15 minutes and adding the 1M Hydrochloric Acid. This process aims to reduce the particle size of RHA. RHA will be used as cement replacement material with the composition that will be displayed in this study. concrete was made on 10 x 10 cm cube mold and a compressive strength test was carried out after 28 days curing. Beside RHA, in this study silica fused is used as cement replacement material. Concrete with the addition of RHA from mechano-chemical process has higher compressive strength than concrete with addition of silica fused.
