On a series of fully hydrated OPC pastes hydrated at two temperatures (20 and 90 Β°C) and on tricalcium silicate pastes hydrated at 20 o the bound water, chemical shrinkage and density of hydrates were determined. Significant differences were found between the compared groups of materials with respec

It is well known that the absolute volume of cement plus water decrease with progressive hydration. In this study, chemical shrinkage of cement was calculated from chemical equation of hydration, it was compared with observed one. Definition of chemical shrinkage and autogenous shrinkage was made an
The drying shrinkage of hardened Portland cement pastes with watercement 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 thermogravimetr
