Inspection Report of Vitrified Microbead Thermal Insulation Mortar

Vitrified microbead thermal insulation mortar is an inorganic dry-mixed thermal insulation mortar produced by mixing vitrified microbeads as aggregate with cementing materials and fibers, and it can be constructed by adding water. The product has good bonding performance, high Strength , and excellent thermal insulation performance. It can be directly constructed on dry walls, the process is simple, and it can improve construction efficiency. After actual inspection, various indicators such as thermal conductivity, heat storage coefficient, Compressive Strength , bonding Strength exceed the performance of ordinary thermal insulation mortar.
