High Quality Silica Powder, SiO2 Nanopowder for Concrete
Product DescriptionSiO2 powder specification:
Particle size: 10-20nm, 20-30nm
Purity: 99.8%
Type: Water soluble, oil soluble
Color: Snow white
MOQ: 1kg
Application of SiO2 nano powder in concrete:
The strength of traditional cement-based materials is low, and a certain amount of nano-silica is added to replace part of ordinary concrete admixture, so as to improve the performance of concrete.
Nano-silica has a special network structure, which can build a new network on the basis of the original network structure of cement slurry, thus forming a three-dimensional network structure, which can greatly improve the physical and mechanical properties and durability of cement slurry.Therefore, nano silica powder can be applied to high strength cement-based pavement materials.
Application Characteristics:
1. Adding nano silica powder into cement mortar can improve the compressive strength, flexural strength at different ages.
2.Can reduce the slumps and expansion ofconcrete.
3.It can increase the self-shrinkage strain of concrete and improve the chloride ion permeability and frost resistance durability of concrete.
4.The transition interface structure between aggregate and slurry in concrete can be improved obviously.
