Thermal and Mechanical Properties of Geopolymers Exposed to High Temperature: A Literature Review

Table 8

Summary of methods for improving residual strength of geopolymers.

Geopolymer type	High-temperature mechanical performance improvement methods
MK geopolymers	Adding melamine resin
	Adding fine CP
	Adding FA
FA geopolymers	Reducing the concentration of activating agent; alkali metal ion is potassium
	Adopting high Si/Al ratio
	Adding fine aggregate
MK or FA geopolymers	Adding SF and QP
	Adding fiber reinforcement
