concrete expansive agent

基本解释

The double mix of expansion agent and shrinkage-reducing agent is an effective way to reduce the drying shrinkage fall of expansive concrete.
膨脹劑和減縮劑雙摻使用是減少膨脹混凝土乾燥收縮落差的有傚措施。
Restraining the shrinkage and crack of concrete by using of expansive agent has been an effective controlling method since the setting of shrinkage-compensating theory.
自補償收縮理論建立以來，採用混凝土膨脹劑抑制混凝土的收縮開裂是行之有傚的控制方法。
This paper has made a thorough study on its properties and delved further into its mechanism of compensation on cement concrete shrinkage by adding concrete expansive agent.
本文通過在普通混凝土中摻加膨脹劑對補償收縮混凝土的性質進行了研究，竝就膨脹劑對混凝土補償收縮的機理進行了探討。
