C70混凝土配合比设计概述

On design of mixing ratio of concrete C70

使用混凝土的强度在不断提高,如何充分利用材料性质,配制出具有较高的强度、耐久性的混凝土是混凝土发展的必然趋势.主要针对高性能、高强度混凝土在设计中的试验情况,从原材料选择、混凝土试配等方面做简单的介绍.经试验验证其结果完全符合JGJ/T55-2000标准要求,适合施工现场使用.

The strength of concrete is increasing constantly all over the world.How to make full use of materials' performance and create the concrete with higher strength and durability is the inevitable trends of development of concrete.The paper mainly aims at the experiments made on the designed high performance and high strength concrete;and makes brief introductions about the selection of raw materials and the trial mixture of concrete.The experiments validate that the results of the concrete accord with the requirements of JGJ/T55-2000;so that the concrete is suitable for use in the construction sites.
