✦ Synopsis

This paper presents results on carbonation of concrete incorporating various constituents including chemical admixtures and fly ash. Both long-and short-term test results are discussed. For concrete with limited initial curing, it was found that the water/cement (not water/binder) ratio was the most reliable parameter in predicting the resistance of concretes to carbonation.Vol.

Chloride ingress into steel reinforced concrete (r.c.), and the subsequent application of electrochemical chloride extraction (ECE) are shown to be considerably retarded by the presence of a carbonation front. Four concrete blocks each reinforced with two layers of steel mats in two different config
