Heavy density silica fume for amusement cement

heavy density silica fume for amusement cement:This type of Microsilica is often added to cement used in the construction of amusement parks to increase the strength and other properties of the cement.

Silica Fume concrete is a new type of concrete made by mixing a certain proportion of silica fume (ultra-fine powdered silica material) in ordinary concrete. Silica fume concrete has the following advantages:
Improvement of strength: As silica fume has high activity, it can have secondary reaction with cement hydration products to form more hydrated calcium silicate colloid, thus increasing the strength of concrete.
Improved durability: As silica fume is able to fill the micropores and cracks in cementitious materials, it reduces porosity and permeability, thus increasing the resistance of concrete to various environmental factors (e.g. carbonation, chloride and salt erosion, freezing and thawing, abrasion, etc.).
