摘要
通过优选高性能减水剂,采用正交实验方法研究了浆体体积、水灰比、砂率对高强度免振捣混凝土工作性能及强度的影响,进而采用不同种类掺合料配置出C80～C100级免振高性能混凝土,经耐久性实验,表明该种混凝土可在实际工程中应用。
By seeking optimum high\|performance water reducing agents and making orthogonal tests, authors studied the influence of volume of mortar, water cement ratio and sand rate on working performance and strength of high performance and non\|vibration concrete. Using different blending materials, they successfully prepared C80～C100 high performance and non\|vibration concrete. The result of durability tests shows that this kind of concrete can be applied in practical projects.
