Mechanical and Physico-Chemical Characteristics of Self-Consolidating Concrete Exposed to Elevated Temperatures

The aim of this research work is to study experimentally the mechanical and physico-chemical characteristics of Self-Consolidating Concrete (SCC) subjected to high temperature. Four different concrete mixes [three SCC mixes and one vibrated concrete (VC) mix] of different strength categories were studied. At the age of 90 days, specimens were placed in an electrical furnace and heated at a rate of 1°C/min until the target temperature was reached. A maximum temperature of 150, 300, 450, or 600°C was maintained for 1 hour. The results showed in particular that the residual compressive strength of SCC increases between 150 and 300°C. Scanning electron microscope (SEM) observations and image analysis showed that the heating of SCC between 150 and 300°C leads to a decrease in the proportion of anhydrous cement particles. The hydration of anhydrous cement due to water transport into the porosity is therefore certainly responsible of the observed strength increase between 150 and 300°C.
