Abstract

Recently, the durability of concrete structures subject to chloride attack and carbonation has been examined in many studies and projects. For the long-term durability and strength of concrete, resistance to calcium leaching from cement hydration is one of the requirements for properties of hardened cement matrix. lt is well known that the ratio of water to binder is one of key parameters affecting the performance of concrete. However, the new design concept should be extended from the mixture proportion to new cement based materials. In this study, the authors examined the efet of grain size and chemical composition of cement on the properties of hardened cement mortar in order to design new sustainable cement based materials, with special focus on compressive strength. lt was found that the presence of large cement particles played a major role in the long-term strength and hydration improvement of cement matrix, and that such role would be improved in combination with the design of the mixture proportion and chemical composition of cement.
