PURPOSE: To perform curing closer to that of temperature history in an actual member with only hydration heat as the heating source outside environment by placing a concrete test piece after kneading into the internal space which is closed by a heat-insulating material wall.YANAGIDA KATSUMI...
Moreover, when heat generating form 1 for curing concrete is used actually, on the side positioned on the opposite concrete surface side, or on one side 2a of the heating element 2 received by each chamber part 6, as an alleviation means having a volume into which at least one selected ...
PROBLEM TO BE SOLVED: To provide a heating cure device which can reduce the dispersion of a cure temperature generated at the time of heating cure of the precast concrete, and also, can inhibit the dissipation of heat from a heat source to the outside, as well as a method for curing th...

The results illustrated that the addition of PFA or CSF as cement replacement could effectively reduce the adiabatic temperature rise and heat generation of curing concrete,while the addition of CSF is much more effectively than addition of PFA in reducing heat generation at the same strength. 展开...
The effect of high-temperature curing at an early age on the strength development of concrete using moderate-heat portland cement was quantitatively studied. High-temperature curing conditions were set so as to give systematic variations in the temperature-time factors. As a result, the integrated ...

Hydration of a greater amount of cement leads to a higher concrete temperature and a larger temperature difference between the middle and the outer surface [1,2]. Consequently, the tensile stress due to the thermal gradient will develop higher, which increase the potential of cracking [1]. Howe...
Ultra-high performance concrete (UHPC) and ultra-high performance fiber reinforced concrete (UHP-FRC) were introduced in the mid 1990s. Special treatment, such as heat curing, pressure and/or extensive vibration, is often required in order to achieve compressive strengths in excess of 150 MPa (...
