The Internal Curing Effect of Pre-saturated Lightweight Aggregate on Cementitious Material
In this paper, the effect of particles size and pre-saturation method of LightWeight Aggregates (LWA) on their water absorption coefficient are investigated (LWA are used to replace a part of the sand), as well as the effect of their particles size and content on the mechanical properties and autogenous shrinkage of mortars. To reach these objectives, two methods are performed to saturate LWA: normal and vacuum saturation. Additionally, two particles size ranges (0–2 mm and 0.63–1.25 mm) and three contents of LWA (0%, 10% and 15%) are also tested. Based on the results, the vacuum condition can effectively increase the water absorption of LWA by about 39%. The addition of finer LWA leads a better effect of autogenous shrinkage and mechanical properties and even slightly improves the mechanical properties of the mortar, thanks to its better spatial distribution.
