摘要
本文总结了分别使用磨细沸石粉、硅灰和粉煤灰作为矿物掺合料配制高强混凝土的试验结果 ,分析了这些矿物掺合料对高强混凝土的强度和流动性的影响及适宜的用量范围。本文还介绍了C60泵送粉煤灰高强混凝土在北京航华大厦工程中的使用情况 。
This paper presents the result of the experiment on mixing high strength concrete using zeolite powder,slica fume and fly ash as mineral admixture,respectively,in concrete.The effects of these mineral admixtures on strength and flowability of concrete and the optimal quantity of these mineral admixtures in concrete were analyzed and determined.In addition this paper introduces the application of C60 fly ash pumped high strength conerete in Hanghua Tower in Beijing and presents some properties of concrete as well as the effects of anti feezing agent on high strength concrete in winter construction.
