摘　　要：硅粉细度大,活性高,添加硅粉的混凝土强度增加极大,但硅粉需水量极大。高炉矿渣需水量较小,前期强度较低,但后期强度呈明显增加趋势,且有递减混凝土水化热的效果,若将这两种混合料同时添加,预期可形成互补,产生叠加效应。Silicon powder has high fineness and high activity.The strength of concrete added with silicon powder increases greatly,but silicon powder requires a great amount of water.The blast furnace slag requires less water,and the early strength is lower,but the strength in the later stage is obviously increasing,and it has the effect of decreasing the hydration heat of concrete.If these two mixtures are added at the same time,it is expected to form a complement and produce a superposition effect.
