本文介绍了一种新型改质水泥防水剂DCW的配方范围及技术原理 ,并用该防水剂代替混凝土中水的含量制成试件 ,对混凝土的常规机械性能进行了测试。试验结果表明 :该改质防水剂不仅使C3 0混凝土抗渗标号达到S10 ,还使其抗压强度提高 3 0 %左右 ,水泥的抗压强度提高 15 %左右 ,同时提高了C3 0混凝土的抗劈裂性能和抗冻融性能。此外 ,该防水剂价格低廉 ,它为工程防水施工提供了一种最佳选择。
This paper introduces the formulation range and technical principle of a new type of modified waterproofing agent DCW, and uses the waterproofing agent instead of the water content in concrete to make the test piece to test the conventional mechanical properties of concrete. The test results show that the modified water-repellent agent not only achieves the S10 impermeability of C3 0 concrete, but also increases the compressive strength by about 30%, the compressive strength of cement by about 15% and the concrete resistance of C3 0 concrete Splitting performance and anti-freeze-thaw performance. In addition, the water repellent inexpensive, it provides a water-resistant construction project is the best choice.
