- Synopsis
- The use of high-strength mass concrete has increased in recent years,with a tendency toward constructing tall and large-scale reinforced concrete structures. At an early age,the interior of mass concrete is heated and cured at high-temperatureby internal storage of the heat of cement hydration. High-temperature curing at an early age causes a peculiar strength development in mass concrete. Especially,this tendency is remarkable in high-strength mass concrete,because of the increase of cement content per unit volume of concrete. This paper summarizes the general tendencies about the temperature history and the strength development of high-strength mass concrete,with statistical analysis of the experimental data from the previous studies.
