Construction technology of anti-cracking in super long mass concrete base plate

本文介绍了中国人民解放军第二七六五工厂综合楼大体积超长底板混凝土抗裂施工技术。工程通过膨胀加强带的合理设计、膨胀剂的正确选用、配合比的优选,确定了大体积超长底板混凝土抗裂技术方案,以浇筑、养护为施工关键控制点,进行了科学施工,底板取得了良好的抗裂效果,保证了工程质量及工程工期。

This paper introduced the super-long mass concrete slab anti-crack construction technique of Chinese people's liberation army two seven six five factory building. Super-long mass concrete slab anti-cracking technology solutions were fixed by the reasonable design of expansion reinforcing band, correct choose of expansive agent and optimization of concrete mix, we focused on the placing and maintenance, as a result and did good on anti-cracking with the scientific construction, in this way, the construction quality and time for completion were guaranteed.
