product's application
1.concrete or shotcrete
increase its density and strength, improve the performance on its durability,
impact resistance, corrosion resistance, anti-permeability and frost resistance etc
2. refractory material & ceramics material
greatly improve its density, strength and high temperature performance.
3.cementitous repair products (mortars & grouts)
low permeability, increase resistance from chlorides, acids, nitrates and sulfate etc
4.oil well grouting
increase durability and compressive strength, decrease permeability, better control of gas leakage
5. concrete tile, roofing & wallboard,panels
lightweight and improve the strength
6.polymers & rubber product
7.other application, such as waterglass industry, thermal insulation material etc.
