Bétons autoplaçants à haute température
This paper presents an experimental study on the performance of self-compacting concrete (SCC), subjected to high temperature. Three SCC mixtures and one vibrated concrete are tested. Three concrete mixes come from the French National Project B@P. Mechanical and microstructural properties are studied at ambient temperature and after heating, namely the compressive strength, flexural strength, bulk modulus of elasticity, porosity and permeability. For each test, the specimens are heated at a rate of 1°C/min up to different temperatures (150, 300, 450 and 600°C). In order to ensure a uniform temperature throughout the specimen, the temperature is held constant at the target temperature for one hour before cooling. In addition, the specimen mass is measured before and after heating in order to determine the loss of water during the test.
