摘要
介绍了Ｃ７０、Ｃ８０高性能混凝土（ＨＰＣ）的配制和性能。Ｃ７０、Ｃ８０ＨＰＣ主要是通过充分调动水泥、活性细掺合料和混凝土外加剂的协同作用而研制成的，其强度保证率为９８％，低水胶比恰当、水泥和复合胶凝材料总量低。
This paper deals with the research on the preparation and physical mechanical properties of C70 & C80 high performance concrete(HPC).The C70 & C80 HPC has benn successfully prepared by full using the cooperative effects of Portaland cement,active superfine powders and high range water reducing agent.Its water binder ratio is properly low.It has a probability of strength guarantee of not lower than 98%,with a lower cement content and totao binder content.
