对三组不同掺量的煅烧硅藻土再生细石混凝土与普通细石混凝土做了对比试验,指出三组再生混凝土7 d强度随着硅藻土掺量的增加而降低;28 d强度均低于普通混凝土;硅藻土掺量3%的混凝土强度略高,建议煅烧硅藻土掺量控制在3%以内。
Three groups of calcined diatomite recycled fine aggregate concrete with different dosages were compared with conventional fine aggregate concrete. The results showed that the 7 d strength of three groups of recycled concrete decreased with the increase of diatomite content, and the strength at 28 d was low In ordinary concrete, the strength of concrete with diatomite content of 3% is slightly higher, and the dosage of calcined diatomite is recommended to be controlled within 3%.
