Development of eigenstress due to drying shrinkage in hardened Portland cement pastes: Thermomechanical analysis
The drying shrinkage of hardened Portland cement pastes with water-cement ratio from 0.25 to 0.70 was characterized in terms of shrinkage eigenstress determined by thermomechanical analysis (TMA). The eigenstress development with water loss during thermal drying was investigated using thermogravimetric and thermomechanical analyses (TGA and TMA). Two major periods of water loss during thermal drying were observed at about 50 Grad C and 90 Grad C. Drying mechanisms associated with each of these are discussed. The ultimate eigenstress values for different Portland cement pastes obtained from TMA appear to be much less than the normal tensile strength developed in Portland cement pastes.
