N2 - This study aims to investigate experimentally how internal curing by Porous Ceramic Aggregate (PCA) made of roof material wastes is effective in enhancing properties of fly ash concrete like compressive strength, pore structure and shrinkage. Longer moist curing is needed for fly ash concrete to develop the required performance. In this study three exposure conditions, namely sealed condition, exposure to the air at 3 days and 7 days are adopted. Results showed that internal curing by PCA was effective in developing compressive strength after the age of 28 days under sealed condition as well as in reducing autogenous shrinkage, and tended to increase slightly the pore volume under sealed condition.
