Chemical Shrinkage and Self-Desiccation in Portland Cement Based Mortars.
(1999) In Concrete Science and Engineering 1(4). p.228-237- Abstract
- This article outlines an experimental and numerical study of self-desiccation and chemical shrinkage in Portland cement mortars, with or without silica fume. For this purpose 9 different cement mortars were cast in 90 pycnometers (study of chemical shrinkage and hydration) or 180 glass flasks (study of self-desiccation and hydration). Chemical shrinkage was observed for 14 days and self-desiccation for 70 days. Parallel studies were carried out on evaporable water (only cement mortar with sealed curing) and hydration. The results indicate that silica fume slightly affects the specific volume of the hydrated water. The silica fume also had a substantial (physical) effect on the self-desiccation when used in Portland cement mortars.
