Introduction
Alkali-resistant glass fiber has high tensile strength and elastic modulus, good chemical stability and thermal stability. Cement coagulation
Alkali-resistant glass fibers for soil and mortar are fibers that are chopped from continuous alkali-resistant glass fibers. Adding alkali-resistant glass to cement concrete and mortar
Glass chopped fiber can control the cracks of concrete and mortar, improve the impermeability, crack resistance, impact resistance and corrosion resistance of concrete and mortar
It improves the toughness of concrete, and the construction performance is good. The density of alkali-resistant glass fiber is similar to that of cement concrete or mortar.
Scattered, stable volume, and good workability, so alkali-resistant glass fiber has good crack resistance, toughening, and strengthening effects on concrete and mortar, and can be widely used
Used in water conservancy, transportation, military, offshore, construction and other projects.
Alkali-resistant glass fiber for cement concrete and mortar
