摘　　要：研究了不同掺量抗裂硅质防水剂对混凝土工作性能、力学性能、抗渗性能以及体积稳定性能的影响。结果表明：掺入适量的抗裂硅质防水剂有利于改善混凝土性能;随抗裂硅质防水剂掺量的增加,混凝土的和易性、力学性能、体积稳定性呈先增强后降低;当掺量为胶凝材料的5%时,混凝土的和易性、力学性能和体积稳定性较佳;掺量为胶凝材料的5%~7%时,混凝土抗渗性能较佳。The influence of different content crack resistance silicon waterproofing on working properties,mechanical properties,anti-penetrability performance and volume stability of concrete was studied. The results obtained indicate that the concrete performance can be improved by adding crack resistance silicon waterproofing. With the increase of crack resistance silicon waterproofing content,the workability,mechanical properties,volume stability of concrete can be increased first,and then decreased. When the content of waterproofing is 5% of the binding material, the concrete has a better workability,mechanical properties and volume stability. When the content of waterproofing is 5%~7% of the binding material,the concrete has a better anti-penetrability performance.
