Traditional cement-based materials have low strength. Adding a certain amount of nanosilica replaces part of the ordinary concrete mix, thereby improving the Properties of concrete. This product has been specially treated with nanometers to make the surface energy of nanosilica higher. It can easily form chemical bonds with the hydration products in the cement stone to produce gel. Moreover, nanosilica has a special network structure and can A new network is established based on the original network structure of the cement slurry to form a three-dimensional network structure, which can greatly improve the physical and mechanical properties and durability of the cement slurry. Therefore, nanosilica can be applied to high-strength cement-based pavement materials.

Application characteristics of nano-silica:
, mixed in cement mortar Adding nano-silica can improve the compressive and flexural strength of cement mortar at all ages. ?
, can reduce the slump and expansion of concrete.
It can increase the autogenous shrinkage strain of concrete and improve the permeability resistance and frost resistance durability of concrete.
, can significantly improve the transition interface structure between aggregate and slurry in concrete.
It is recommended that the nano-silica material be mixed into the liquid water-reducing agent before use, and then mixed with other materials.
Adding amount: Recommended adding amount -, users can experiment according to their actual situation and choose the best added value.
