Contribution and function to durability of water-cement ratio and the blending material in HPC is discussed.
从混凝土的渗透性、碳化、抗氯离子侵蚀、抗冻性、碱—骨料反应等方面综述了高性能混凝土的耐久性,探讨了水灰比及常用掺合料对混凝土耐久性的贡献及作用机理,指出高性能混凝土应是混凝土材料发展的首选方向。
By using different blending materials,non-vibrated HPC with C80～C100 strength were achieved.
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推广应用。
Test results indicate that adding 10 percent ultra-fine lime stone powder blending material can obviously improve the early compression strength of concrete,and that the bending strength of concrete will be improved along with increase of addition amount of lime stone powder when the addition amount is less than 30 percent.
结果表明,掺入10%的超磨细石灰石粉掺合料可显著提高混凝土的早期抗压强度,当石灰石粉掺量小于30%时,抗折强度随其掺量的增加而提高。
