Evolution of microstructural changes in cement paste during environmental drying

Exposure of concrete to the atmosphere changes the microstructure of the cement paste. However, knowledge about the alteration of the porosity due to drying is typically not considered in deterioration processes of the hardened cement paste. The purpose of this article is to emphasize the importance of the porosity changes due to drying. 1 mm thick discs specimens made with four different pastes including three blended cements were exposed to...
