高强混凝土的试验研究

Expetimental Study of High-Strength Concrete

在试验研究的基础上，本文主要探讨了水泥标号、砂细度模数、碎石级配及最大粒径、高效减水剂的品种及掺量、混凝土成型工艺等主要因素对高强混凝土强度和工作度的影响，并测用高强混凝土部分物理力学性能，为工程应用高强混凝土提供一些试验依据。

Based on investiBation and test, this paper discusssrs emphatically the effects of the factors, such as grade of cement, fineness modulus of sand, grading and maximum syze of aggregate, type and dosage rate of high-range water-reducing admixture, forming techniques of concrete etc. on the strength and workability of high-strength concrete. Part of physico- mechanical propertias of high-strength concrete is measured at the same time, some considerations are given for engineering applications of high-strength concrete.
