摘要
引气剂的掺入能在混凝土中引入大量均匀、稳定的微小气泡,提高混凝土的耐久性能;但影响混凝土含气量大小的因素众多,环境气压就是其中一种。研究结果表明,随着环境气压的降低,相同配合比混凝土的含气量有降低的趋势。
With the blending of air-entraining agent, plentiful of tiny blisters fill homogeneously stably in the concrete. It greatly improves the concrete's durability. However, considerated what affect concrete's air-containing are so many, one of them is the air pressure of environment.The researches indicate that concrete's air-containing dropping as the air pressure of environment dropping.
