heavy density silica fume for guest houses

Heavy density silica fume for guest houses: This heavily encrypted micro silica is usually added to the concrete used in the construction of hotels.1. Improve the early strength and final strength of concrete Domestic research surface, when the replacement rate of silica fume to cement is 30% or less, the autoclave temperature is 80 ℃, the compressive strength of mortar one day for not mixed with silica fume 2 times, if the autoclave curing, it is almost 3 times; standard curing, the compressive strength of mortar is also significantly increased. Increase compactness Concrete mixed with silica fume increases the reactive microsilica content, observed under the electron microscope, mixed with silica fume concrete cement stone voids in the crystal growth. In addition, the silica fume particles are very small, uniformly fill the concrete microporous, micro-aggregate filling effect is obvious. Improvement of concrete segregation and water seepage performance After pouring concrete,…
