High-strength concrete for PC component and preparation method of high-strength concrete
The invention relates to the technical field of concrete, and provides high-strength concrete for PC components and a preparation method thereof.The high-strength concrete is prepared from 90-100 parts of cement, 15-20 parts of blast furnace slag, 32-42 parts of carbide slag, 12-18 parts of zeolite powder, 15-25 parts of modified fibers, 1-5 parts of early strength agent, 0.01-0.015 part of air entraining agent, 1-2 parts of water reducing agent and 45-55 parts of water; the modified fibers comprise nickel-plated carbon fibers and aramid fibers in a mass ratio of (1: 19)-(19: 1). By means of the technical scheme, the problems that in the prior art, concrete is low in strength and poor in abrasion resistance are solved.
本发明涉及混凝土技术领域，提出了一种PC构件用高强度混凝土及其制备方法，高强度混凝土包括水泥90~100份、高炉渣15~20份、电石渣32~42份、沸石粉12~18份、改性纤维15~25份、早强剂1~5份、引气剂0.01~0.015份、减水剂1~2份、水45~55份；改性纤维的组分包括质量比为1:19~19:1的镀镍碳纤维和芳纶纤维。通过上述技术方案，解决了相关技术中的混凝土的强度较低和耐磨性较差的问题。
