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7d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 recycled fine aggregate concrete and normal fine concrete were done contrast test. Recycled concrete 7 d strength grad-ually reduce with the increase of diatomite proportion,research shows that:the three groups of recycled concrete 28 d strength were lower than that of normal concrete,higher for the concrete with 3% proportion. Suggest calcined diatomite proportion control within 3%.
