Abstract
To investigate the mechanical properties of alkali-activated slag ceramsite concrete blocks after exposure to high temperature, compression tests were conducted on 48 alkali-activated slag ceramsite concrete blocks with two strength grades, MU10 and MU20, and all the specimens were exposed to normal temperature and a temperature history of 400℃, 600℃, 700℃, 800 ℃, 900℃, 1 000℃, and 1 100℃. The results show that the compressive strengths of MU10 and MU20 ceramsite concrete blocks exhibited a linear decrease with the increase of the heating temperature from 20℃ to 1 100℃. Based on the test results, the formulas were constructed to calculate the compressive strengths of the alkali-activated slag ceramsite concrete blocks after exposure to high temperature in term of the heating temperatures.
