Abstract: High-early-strength concrete (HESC) made of Type III cement attains approximately 60%–70% of its design compressive strength at ambient temperature in 1 day. A numerical method incorporating a rate-constant model was ...

Abstract: During steam curing of concrete, the axial restraint of pretensioned strands causes thermal prestress loss of the strands accumulated until sufficient bonding occurs. A theoretical model is presented in this paper to predict ...

Abstract: The optimum curing regime (OCR) empirically obtained from a number of small-sized specimens may be overly conservative or inaccurate due to neglecting the effects of exothermic hydration and geometries of full-sized members ...
