Effect of solvent exchange on length change and creep of D-dried hydrated C3S paste
Source abstract
Abstract
The results of a study on creep of D-dried hydrated C3S paste after exchange of water in saturated samples with organic solvent are presented. Length and mass changes were also measured when saturated C3S paste prepared at a water-solid ratio of 0·4 was immersed in both methanol and isopropanol. A differential thermogravimetric technique was used in order to determine the effect of solvent treatment on dehydration of C3S paste, and its correlation with pore structure, modulus of elasticity and microhardness. Methanol and isopropanol exchanges prior to drying reduce the magnitude of creep in the dry state, suggesting an irreversible interaction of solvent with C-S-H.
