The effect of grinding time on the properties of low-temperature rice husk ash was experimentally studied, and the feasibility of using rice husk ash instead of silica fume to prepare concrete was studied by comparison with silica fume. The results showed that the best grinding time of rice husk ash is 50 minutes, the concrete with similar properties can be prepared by replacing silica fume with super-fine rice husk ash, and the same enhancement effect can be achieved when replacing silica fume with more than 5%, and the performance was consistent.
