EFFECTS OF EARLY AGE CURING ON DURABILITY-RELATED PROPERTIES OF CONCRETE

This paper presents an experimental investigation in which every effort was made to eliminate factors that would otherwise mask the real influence of curing on the durability-related properties of concrete. The transport-based testing regime developed allowed cover thickness specimens to be tested sequentially for sorptivity, vapor diffusion, and gas permeability. Mercury intrusion porosimetry and scanning electron microscopy were used to investigate the effects of curing on microstructure. Despite the inherent variability associated with transport tests, the testing regime was effective in discriminating between the short-term effects of the different curing schemes on concrete transport properties. Generally, the effect of water-content was more important than the effect of curing.
