Drying behaviour reflects the mass transport properties of concrete to a certain extent, based on many factors such as: (a) concrete mixture proportions; (b) presence of chemical admixtures and supplementary cementitious materials; (c) composition and physical characteristics of the cementitious components and aggregates; (d) entrained air content; (e) curing type and duration; (f) degree of hydration and age; (g) presence of microcracking; (h) presence of surface treatments such as sealers or form oil; and (i) placement method, including consolidation and finishing. Concrete drying is also strongly affected by the moisture condition of the concrete at the time of testing and the controlled temperature and relative humidity environment.
