Effect of Aggregate Type on the Behavior of Thermally Treated Self-Compacted Concrete
This paper conducted with studying the physieomechanical and microstructure characteristics of self-compacted Concrete (SCC) with different types of aggregate (Basalt, Gravel and Dolomite) in high temperatures for different time of exposure. The changes in the physico-mechanical properties of SCC due to high temperature were examined. The evaluation of fresh SCC properties was based on the results of slump-flow test, J-ring test and V-funnel flow test. The change in mechanical properties, porosity, absorbtivity, bulk, and real density with the increase of high temperature at different time of exposure were also recorded. The phase composition and microstructure were investigated by differential scanning calorimetry (DSC). Experimental results show that the aggregate type have a clear effect on fresh properties of SCC and also the high temperature has a clear effect on both physico-mechanical and micro structural characteristics of SCC.
