现浇混凝土与铝合金模板面层产生化学反应的质量通病控制研究

Study on Common Quality Defects Control of Chemical Reaction Between Cast-in-Place Concrete and Aluminum Alloy Formwork Surface

针对铝合金模板面易与混凝土发生化学反应的问题,特对现浇混凝土工程中运用铝合金模板的施工质量进行了一系列试验研究,找到了一种对铝合金模板面层有效的钝化处理方法,继而通过优化混凝土配合比设计、合理选用脱模剂,大大改善了采用铝合金模板施工的混凝土结构成形质量。

Aiming at the problem of common chemical reaction between aluminum alloy formwork and concrete,a series of experimental studies on the construction quality of using aluminum alloy formwork in cast-in-place concrete engineering were carried out specially,and an effective passivation method for aluminum alloy formwork surface was found.Then the forming quality of concrete structure adopting aluminum alloy formwork construction was greatly improved by optimizing the concrete mix proportion design and reasonably selecting the release agent.
