... of the concrete were evaluated (density, porosity, crack width and residual compressive strength). The comparative performance of CC and GC was analyzed using experimental results. Findings Results showed that a decline in density and compressive strength, alongside an increase in porosity and crack width...

... for different exposure times. Design/methodology/approach An experimental work is carried out to compare the conventional and optimal concrete with respect to weight loss, mechanical strength characteristics (compressive, tensile and flexural) after exposed to 100, 200 and 300 °C with 1, 2 and 3 h duration...

... Recrystallization of TMT rebar crystals took place around 500 °C, which led to a decrease in the dislocation density along with the increase of large-sized grains, resulting in the degradation of strength. Up to a temperature range of 500 °C, the normalized fracture strength was higher, while the normalized...
