DURABILITY OF SELF-CURE CONCRETE

When cured in air, 'self-cure' concrete possesses improved properties in comparison to identically cured controls. This paper reports the re sults of several durability tests conducted on self-cure concrete spec imens. It was found that initial surface absorption, chloride ingress, carbonation, corrosion potential and freeze / thaw resistance charact eristics were all better in air cured self-cure concrete than in the a ir cured control. This improvement appears to be dependent on admixtur e dosage, and although the durability properties obtained in this stud y were not as good as the film cured concrete controls, it may be poss ible to achieve such properties with higher quantities of self-cure ch emical.
