Nano silicon dioxide powder for concrete (Nano SiO2)

The strength of traditional cement based materials is low, adding a certain amount of nano SiO2 powder instead of a part of ordinary concrete miscible aggregate, thereby improving the performance of concrete. After special nano treatment, the surface of nano silicon dioxide powder can be enhanced, and it is easy to form bonds with hydration products in cement paste to produce CSH gel. Moreover, nano SiO2 has a special network structure, which can establish a new network on the basis of the original network structure of cement paste, thus forming three dimensional. The network structure can greatly improve the physical and mechanical properties and durability of cement paste. Therefore, nano silica can be applied to high strength cement based pavement materials.
