This paper presents the results of carbonation and shrinkage studies of nonplastic, expanded slag concrete made with and without fly ash. Test specimens were subjected to moist, treatments at various ages and concentrations were used. All low pressure steam and high pressure steam curing conditions. Five different storage conditions specimens were subjected to a final carbonation and two including normal air drying, oven drying, and carbonation wet-dry cycles at the end of the storage period. Test results show that some carbonation treatments are effective in re-ducing later shrinkage.
