A Study on Development of Curing Apparatus for In-place Standard Curing Specimen

현장 표준양생 공시체 관리함의 개발에 관한 연구

In-place curing box for specimens is used to cure the compressive strength specimens for control in place concrete. The box if composed of insulating chamber maintaining 20$\pm$3$^{\circ}C$ of temperature, in this paper, strength and temperature history of specimens cured at in plate curing box are investigated to verify field applicability. According to test results, air temperature at measured time shows large temperature variation and below zero, whereas, inside temperature of in place curing box maintains within 20$\pm$3$^{\circ}C$ due to temperature control function. For curing condition. temperature of specimens cured at outside shows large temperature deviation. specimens lured at in-place curing box is not affected by outer temperature.
