摘　　要：利用超细碳酸盐岩粉不同的粒度分布使粉体颗粒之间发生紧密堆积效应，这样设计出的混凝土不但有良好的出机状态，而且具有良好的力学性能和耐久性能，特别是对减小混凝土温升、提高抗渗性、减小收缩、防止开裂的作用显著。掺超细碳酸盐岩粉的混凝土可以减少40％左右的水泥用量，是一种更加绿色环保的高性能混凝土，具有较好的社会经济效益。Making tense-packing effect happens between powder particles by using the different particle size distribution of ultrafine carbonate powder, the concrete designed according to this has not only good out-of-machine state, but also good mechanical properties and durability, especially has significant effect on decreasing the temperature rise of concrete, increasing impermeability, decreasing shrinkage and preventing cracking. The concrete doped ultrafine carbonate powder can decrease about 40% cement content, which is a more green environmental protection high performance concrete and has good social and economic benefits.

关 键 词：超细碳酸盐岩粉 粒度分布 紧密堆积效应 耐久性 绿色环保
