高抗冻防水混凝土(C35P8D300)的研究与应用

Research and application of high frost-resistance and waterproof(C35P8D300) concrete

目前,对高抗冻混凝土的试验主要是以高强度混凝土为基础,通过较大的水泥用量配合其它方式来对混凝土进行改性设计。对于C35P8D300的配合比设计,则要在较低水泥用量的情况下达到其较高的抗冻性能和抗渗性能。本文通过在聚羧酸中添加适量的引气剂,优选合适的原材进行了大量的试验研究,成功配制了C35P8D300混凝土并在工程中应用。

Currently,the high frost-resistance of concrete test primarily is based on high-strength concrete,by large cement dosage combined with modification of concrete design in other ways.The design of C35P8D300 is at a lower dosage of cement reached its high frost resistance and impermeability.This article in the poly-carboxylic acid by adding the right amount of air-entraining agent,optimization of raw material suitable for a large number of experimental studies,C35P8D300 was prepared successfully and applicated in engineering.
