HIGH EARLY STRENGTH CONCRETE COMPOSITION UNNECESSARY FOR STEAM AGING

摘要

Disclosed is a concrete composition for expressing early strength with unnecessary steam curing, which is capable of securing the strength at least 10 MPa within 6 hours of curing without performing steam curing such as boiler or the like and without change in material properties of cement. According to the present invention, a concrete composition for expressing early strength with unnecessary steam curing, as a concrete composition for expressing early strength with unnecessary steam curing so as to express compressed strength at least 10 MPa within 6 hours of curing without performing steam curing, can be applied to high early strength cement, with addition of 5-8 parts by weight of a hardening accelerator with respect to 100 parts by weight of the high early strength cement.
