摘要
高强混凝土和高性能混凝土因其水胶比都很低，给配制与施工带来如下现象：如水泥标号的“标志”作用淡化，矿物掺合料的作用显著改善，拌合物的高粘聚性、混凝土的收缩和徐变性能的变化等，这些现象都值得施工人员注意。
Because the water-binder ratio of both high strength concrete and high performance concrete are very low,it bring about the following consequences such as:1,the grade of cement strength would be a negligible symbol 2,the effectiveness of mineral admixture would be considerably improved 3,the high cohesion of the mixture and concrete's shrinkage and creep would be changed etc.All these consequences should be well deliberated by the construction circles.
