Abstract:
Research conducted at the Diponegoro University resulted in the development of an FEM program for analyzing the influence of the Interfacial Transition Zone (ITZ) between the aggregates and the mortar, in concrete. It was shown that indeed, the ITZ has a substantial weakening effect to the ultimate strength and stiffness modulus behavior of concrete. High wcf, bleeding and the presence of a water film surrounding the aggregates, resulted in a decrease of the ITZ quality. The study was further expanded to analyze this weakening effect to a twostory building. It was found that the condition of the ITZ considerably influences the overall performance of a structure.
