引气剂与混凝土高性能化

Air-entraining agent effect to high performance of concrete

本文论述了引气剂的研究和应用现状、作用机理,并重点探讨了引气剂对新拌混凝土和硬化混凝土性能的影响。掺加引气剂能够明显改善混凝土工作性,提高其耐久性,满足工程对混凝土特定性能的要求,本文指出引气剂应是今后发展高性能混凝土的必备外加剂。

Research and application actuality, action mechanism of air-entraining agent were discussed, and we pay more attention to the effect of air-entraining on new and hardened concrete. Air-entraining agent can improve workability and durability of concrete which satisfy the need of project on special performance of concrete. Air-entraining agent should be a necessary admixture of high performance concrete in future.
