Semi-encrypted silica fume for school concrete

Semi-encrypted Microsilica for school concrete：This Semi-encrypted silica fume is commonly added to concrete used in the construction of schools to increase the frost resistance and corrosion resistance of the concrete, among other things.

1. Increasing compactness
Adding micro silicon powder to concrete can fill the micropores in concrete and improve the compactness of concrete, thus increasing the water resistance and durability of concrete. Because the micropores in concrete easily allow water to pass through, resulting in a decrease in the mechanical properties of concrete, and also reduce the mechanical strength and crack resistance of concrete.
2. Promote hydration reaction
Silica Fume can be hydrated with cement to form a more stable silicate colloid, thus improving the strength of concrete. silica fume can act as the core reactant in concrete, participate in the hydration reaction of cement, reduce the amount of cement in concrete, and at the same time improve the strength and durability of concrete.
3. Preventing cracking
The addition of silica fume to concrete reduces the volume of concrete and prevents it from cracking due to temperature changes, water loss and other factors. Silica fume acts similarly to an additive expander, increasing the toughness and vertical deformation of the concrete, thus improving the cracking resistance of the concrete.
