Density, expansion and intrinsic shrinkage were studied on hydrated cement compacts made of Portland cement, with and without gypsum, and of different initial porosities. Results confirm former observation that the average density of the hydration products increases as the hydration proceeds reachi

A previously postulated hypothesis that concrete or mortar prisms devoid of free Ca(OH)~ will not suffer from alkali-silica expansion has been tested. In this investigation high slag-Portland cements were used to make mortar prisms with a reactive sand. Storage of these prisms in a saturated NaCl ba

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
