本文根据建设部部颁标准(JGJ15—83)《早期推定混凝土强度试验方法》,对加速养护箱的技术规定:“加速养护箱应能保证箱内各处水温保持在规定温度±2℃之内,热源应能保证于试件放入水箱后15分钟内使箱内水温恢复到规定的温度。加速养护箱具有自动控制温度装置时,还应独立于温度自动控制系统之外的温度计或其他的测温装置校核水的温度”。结合我们研制、试验、使用自制混凝土试块自控快养恒温箱的经验和混
This article according to the Ministry of Construction standards (JGJ15-83) “Early Predicted Concrete Strength Test Method”, the technical requirements for accelerating the curing box: “Accelerating the conservation of the box should be able to ensure that the water temperature inside the box is maintained within the specified temperature of ± 2 °C The heat source shall ensure that the water temperature in the tank is restored to the specified temperature within 15 minutes after the test piece is placed in the tank.When the accelerating curing tank has an automatic temperature control device, it shall be independent of the thermometer or other than the automatic temperature control system. The temperature measuring device checks the temperature of the water.” In combination with our experience in the development, testing, and use of self-made concrete block self-controlled fast-keeping incubators
