Latest Progress of Mechanical Properties of Geopolymer Concrete at Elevated Temperature

Abstract

In order to alleviate the environmental pollution and energy consumption problems caused by ordinary Portland cement, geopolymer came into being as a new type of green building material. The special three-dimensional mesh structure of geopolymer concrete makes it show excellent durability under fire, so it has been deeply studied by many scholars. This paper mainly expounds the research results of the basic static properties of inorganic geopolymer concrete at high temperature from the following four aspects: compressive strength, tensile strength, modulus of elasticity and stress-strain relationship. Due to the obvious differences in the mechanical and structural properties of geopolymer concrete in terms of raw materials, mix ratio, curing temperature, etc. There is no corresponding material and structural design specification for geopolymer concrete and it needs more incisive research before it applies to engineering construction.
