Keywords: concrete, microstructure, phase compositions, mechanical property, curing, NaCl solution


The effects of cyclic curing (CC) alternating between NaCl solution immersion and drying for 28 d on the microstructure, phase composition and mechanical properties of ordinary concrete are studied in comparison with those cured by standard curing using municipal water. Compared to standard curing, CC enhances the compressive strength, flexural strength and static compressive elastic modulus of concrete by (5.71, 11.14 and 8.06) %, respectively. Ca(OH)2 is significantly reduced, while C-S-H is increased, and a minor amount of 3Ca(OH)2·CaCl2·12H2O is formed. Hydration products become finer, more uniform and denser. The use of CC is proposed as it improves the strength.
