摘　　要：配制C80混凝土使用质量稳定、颗粒级配较好、强度富裕系数大的52.5普通硅酸盐水泥;粗骨料选用最大粒径不大于20mm的碎石;细骨料为细度模数2.6左右的中粗砂;矿物掺合料选用一级粉煤灰与S95精细硅粉、矿渣粉复掺;外加剂选用聚羧酸减水剂与BTC功能型外加剂复掺;水胶比0.26左右;研究不同比例搅拌站废浆作为拌和用水对A、B组矿物掺合料C80混凝土强度的影响。C80 concrete is made of 52.5 ordinary Portland cement with stable quality, good particle gradation and large strength abundance coefficient. Coarse aggregate should be crushed stone with maximum particle size of no more than 20 mm. Fine aggregate is medium coarse sand with fineness modulus about 2.6.The mineral admixture is mixed with S95 fine silica powder and slag powder. Polycarboxylic acid superplasticizer and BTC functional admixture were selected as admixtures. Water-binder ratio is about 0.26.The effect of waste slurry in mixing station with different proportions as water for mixing on the strength of group A and group B mineral admixture C80 concrete was studied.
