As we all know, the price of a product is determined by supply and demand. The bottom line of the price of a product is
Silica fume is a high performance mineral admixture of volcanic ash, mainly used to improve the strength and durability of concrete, and can replace silicate
Low-heat concrete Replacing cement with micro silica fume, the strength remains the same while the temperature of concrete changes, which is the most effective way
Silica fume is Microsilica powder, the main component is silica, is a powder material obtained by cooling the smoke produced by ferrosilicon smelting, widely used
Fumaça de sílica, também chamada de microssílica ou sílica ativa coesiva ou sílica ativa condensada, é produzido por ferroligas na fundição de ferrossilício e silício industrial (silício metálico),
Common Causes of Ground Dusting 1. Excessive water-cement ratio of the cement mortar (excessive mortar consistency) reduces the strength of the plastering layer. The larger
There are two main reasons for loose structure and low strength of concrete surface: 1) The water-cement ratio of the concrete surface is larger than
