Mix Ratio Design and Performance Optimization of Vitrified Microsphere Insulating Mortar

Abstract:

Vitrified microsphere insulation mortar is a new type building insulation mortar which developed in recent years, with having the advantages of well workability, high intensity and fire prevention. But because the vitrified microsphere we use of which much exists on the defects of high dry density and bad insulation effect, it analyzed deeply kinds of factors which influence on the physical and mechanical properties of vitrified microsphere insulation mortar, making use of orthogonal experiment to optimize the composition materials of insulation mortar. The orthogonal test results show that the most influential raw materials factors to mortar insulation properties and 28d compressive strength followed by aggregate, polypropylene fiber, fly ash and latex powder.
