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

Table 5

Stress-strain curves for different geopolymers at room temperature.

Samples	M1	M2	M3
Peak stress (MPa)	60	46	39
Peak strain (mm/mm)	0.0038	0.0041	0.0035
Variation trend after peak stress	Stress drops rapidly	Stress drops rapidly	Stress decreases slowly
