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
Influences of the volume fraction and the type of aggregate on shrinkage in mortars and concretes made with an expansive cement were examined by using 10 cm x 10 cm x 30 cm prismatic specimens. It was found that the measured shrinkage strains of river sand mortars and crushed stone concretes were no
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
