Durability of 'self-cure' concrete
Concrete that is capable of retaining greater quantities of water than ordinary concrete when cured in air has been developed at these laboratories by means of an addition of a 'self-cure' chemical (SCC), which was a water-soluble polymeric glycol identified as chemical A1 in a previous publication. When cured in air, 'self-cure' concrete possesses improved properties in comparison to identically cured controls. This paper reports the results of several durability tests conducted on self-cure concrete specimens. It was found that initial surface absorption, chloride ingress, carbonation, corrosion potential and freeze / thaw resistance characteristics were all better in air cured self-cure concrete than in the air cured control. This improvement appears to be dependent on admixture dosage, and although the durability properties obtained in this study were not as good as the film cured concrete controls, it may be possible to achieve such properties with higher quantities of self-cure chemical.
