Fiber-reinforced aerogel cement-based material and method for its preparation

Abstract

The application discloses a kind of fiber reinforced aerogel cement-based materials and preparation method thereof, fiber reinforced aerogel cement-based material includes cementing material, aggregate system, additive and PVA fiber;Cementing material includes cement, silica fume, fly ash;Aggregate system includes sand, SiO2 Aerogel particle, vitrified microsphere;Additive is water reducing agent;The mass ratio of aggregate system and cementing material is 0.38;Sand in the mass percentage of aggregate system is 75.2%~84.6%, the mass percentage of SiO2 Aerogel particle in aggregate system is 6%, the mass percentage of vitrified microsphere in aggregate system is 9.4%~18.8%.The application provides a kind of fiber reinforced aerogel cement-based material and preparation method thereof, the incorporation of PVA fiber can improve the compressive strength of cement-based material to a certain extent, and the incorporation of PVA fiber has significant strengthening effect on the toughness of cement-based material.
