[1103] NUMERICAL SIMULATION OF PROPERTIES OF DRIED CONCRETE CONSIDERING INTERFACIAL TRANSION ZONE
Keywords:compressive strength, crack, drying, inter facial transition zone, shrinkage strain
This paper described new insights on the influence of interfacial transition zone on drying shrinkage strain and compressive strength of concrete through numerical simulation. Using Rigid Body Spring network Model, analysis of drying shrinkage and compression test of drying concrete are performed considering long and short term model of ITZ. As a result, experimental trend is reproduced by using the proposed model. This reproducibility indicated that ITZ characteristics should be taken into account to simulate the shrinkage and strength of dried concrete simultaneously.
