Abstract:The effects of steam-curing at atmospheric pressure were investigated on three kinds of concrete: pozzolanic portland cement concrete, high-strength portland cement concrete, and high-performance concrete manufactured with high-strength portland cement containing a superplasticizer and retarder. The early and final compressive and flexural strengths, coefficients of capillary absorption, and apparent porosities were determined on prismatic specimens stored for 140 days in water and ammonium nitrate solution. The dynamic moduli of elasticity were also measured every week during the storage period. Two steam-curing cycles with maximum temperature of 60 and 80 C, respectively, were used. The steam-curing processes were found to be suitable and less detrimental for high-performance concrete compared to pozzolanic portland cement and high-strength portland cement concretes.
