高效抗裂防水剂在地下工程大体积混凝土中的应用技术研究

Research on Application Technology of Efficient Anti-crack Waterproofing Agent in Mass Concrete of Underground Project

介绍了HEA高效抗裂防水剂在大连某地下室工程大体积混凝土中的应用情况。通过采取抗裂计算优化混凝土配合比、选择合理的施工工艺等措施,保证了该地下工程大体积混凝土刚性防水的质量,工程施工结束1年后,地下室各部位未观测到贯穿性裂缝和渗漏水情况,防水性能达到预期效果。

The article introduces the application of HEA efficient anti-crack waterproofing agent in the mass concrete of a basement in Dalian. Through optimization of concrete composition by anti-crack calculation and adoption of reasonable construction technology, the rigid waterproofing quality of the mass concrete of this basement is guaranteed. One year after the construction completion, no penetrating cracks and water leakages are observed with all the parts of the basement, expected waterproofing performances are reached.
