利用金矿废石经破碎、筛分,制备出符合级配要求的粒径为5~25mm的粗骨料和细度模数约为2.8的人工砂作为配制C60混凝土的粗细骨料。与相同的石灰石粗骨料和河砂配制的混凝土作对比,采用金矿废石配制的混凝土具有良好的工作性能与更高的混凝土抗压强度。相关技术已在烟台万达广场、烟台大悦城等工程中得到成功应用。 The crushed and sieved gold waste rock was used to prepare the coarse aggregate with the grain size of 5-25 mm and the artificial sand with the fineness modulus of 2.8 which meet the gradation requirements as the coarse and fine aggregate for the preparation of C60 concrete. Comparing with the same limestone coarse aggregate and river sand concrete, the concrete prepared by the gold ore waste stone has good working performance and higher compressive strength of concrete. The related technology has been successfully applied in Yantai Wanda Plaza, Yantai Joy City and other projects.
