Research on the influence of Silica fume encryption degree on high strength grade of concrete

Wei Hui;Hu Xiao;Huang Qiulin;Dejiang Tenglong concrete Co., Ltd.;Jiangxi building materials scientific research & design institute;  
Silica fume has good volcano ash activity, can effectively improve the comprehensive performance of concrete, especially in improving the concrete compressive and flexural strength, the effect is more obvious; the silica fume density is small, only 1/10 of original fly ash density cement density, in the production process used to bring a lot of inconvenience, economic benefits is not obvious; the this experimentfound that, half or full encryption encryption of silica fume, does not affect the play to improve the comprehensive efficiency of the effect of concrete. The silica fume by semi or full encryption encryption in the use of transportation and production has brought convenience and economic benefit, benefit to promote the use of silica fume in concrete.
