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。
According to the problems existing in the use of concrete expansive agent in China, suggestions are made on how to correctly use the expansive agent. It is necessary to select the mass ratio of the expansive agent and establish a method for designing the mix proportion of the compensatory shrinkage concrete with the target of limiting the expansion rate, so as to improve the rationality in the structural design. Reinforcement and strengthening of construction management and other measures can make the application of concrete expansive agent better solve the cracking and seepage control problems of building structures.
