Review on the Influence of Raw Materials on the Properties of Gypsum Based Self-leveling Materials

Gypsum based self-leveling materials have excellent fluidity, uniformity, flatness, crack resistance, and high hardening strength.It can fully use desulfurization gypsum, phosphogypsum, fluorogypsum and other industrial wastes.It is a green, environmental friendly, cost-effective and efficient building material for ground leveling.This paper summarizes the influence of raw materials on the properties of gypsum based self-leveling materials, analyzes the relevant mechanism, discusses the shortcomings in the current research of gypsum based self-leveling materials, and puts forward reasonable suggestions for subsequent research.
