Abstract
Moderate-heat portland cement has likely been applied to mass concrete where as in this study it is applied to high-strength concrete with a designed strength ranging from 36 to 70 N/mm2. Fresh properties, strength development and temperature histories of full-scale model specimens of the high-strength concrete have been investigated. It was found that high-strength concrete with moderate-heat cement can be fully applicable to real construction practice on site. Moreover, some important prediction formulas and parameter value were derived : the maximum temperature of the model specimen with parameters of unit cement content and concrete temperatures, relationship between core strength and simplified adiabatic temperatures and a water-cement ratio by which column strengths in structure can satisfy the designed strength.
