Silica fume concrete is a kind of developing composite material, which plays a key role in the construction of high speed railway. It can optimize the use of material for concrete engineering, improve economic efficiency, make the project durable and have little influence on the environment. The physical, mechanical and durability comparison of HPC (high […]

1. Overview of pump concrete: The pump concrete refers that the slump of the concrete mixture is more than or equal to 100mm, and use pump construction team. In the construction site, this type of concrete is usually poured through the pressure pump and the conveying pipe. At present, more and more production enterprises of

The silica fume is also called microsilica or microsilica fume. When ferroalloy is smelting ferrosilicon and industrial silicon (metal silicon). A lot of volatile SiO2 and Si gases are produced in the submerged arc furnace. After the gas is discharged, it is rapidly oxidized, condensed and precipitated with air. It is a byproduct of large
