混凝土膨胀剂使用中存在的问题及解决措施

摘要

The concrete expansive agent has the effect of compensation concrete drying shrinkage, but in basement waterproof concrete engineering, the effect is not ideal, after adding expansion agent the basement slabs and external wall appeared cracking and leakage. This article puts forward the solution measures from the design phase.%混凝土膨胀剂具有补偿混凝土干燥收缩的效果，但在地下室防水混凝土工程中，使用效果不理想，存在掺加膨胀剂后地下室底板和外墙出现混凝土开裂渗漏的现象。本文从设计源头，力求全面地、准确有效地提出解决措施。
