如何正确使用混凝土膨胀剂

How to Use Concrete Expansive Agent Correctly

根据我国混凝土膨胀剂使用中存在的问题 ,提出如何正确使用膨胀剂的意见 ,必须从膨胀剂质量的选择 ,确立以限制膨胀率为目标的补偿收缩混凝土配合比设计方法 ,改善结构设计中的合理配筋和加强施工管理等方面措施 ,才能使混凝土膨胀剂应用能较好地解决建筑结构的裂渗控制问题。

Suggestions of how to use the concrete expansive agent correctly are proposed in the paper, according to the existing problems in the application of concrete expansi/ve agent in China, The measures to be taken should include; the chosen of quality of expansive agent, the correct shrinkage compensating concrete mix design method aiming restricted expansive rate, the rational steel bar management. As long as taking the above measures well, the concrete expansive agent can be used well to solve the problems of craching and permeableness control in architectural structure.
