膨胀混凝土在建筑工程中的应用是近２０年来的事，这也是混凝土工程从有缝设计（设后浇带）到无缝设计（连续浇筑）的工程实践过程。应用膨胀混凝土的目的在于：（１）使超长钢筋混凝土结构保持连续性，满足建筑设计要求；（２）不设后浇带可加快工程进度，防止因后浇带处...
The application of expansive concrete in construction projects has been a thing of the past 20 years. This is also the engineering practice of concrete engineering from seamed design (post-casting belts) to seamless design (continuous pouring). The purpose of applying the expansive concrete is: (1) to maintain the continuity of the super-long reinforced concrete structure to meet the architectural design requirements; (2) to eliminate the post-casting belt to speed up the progress of the project and prevent the post-casting zone from being...
