《GB/T 2022-1980水泥水化热试验方法 （直接法）》由TC184（全国水泥标准化技术委员会）归口，主管部门为中国建筑材料联合会。
本标准适用于测定水泥水化热。本标准是在热量计周围温度不变条件下，直接测定热量计内水泥胶砂温度的变化，计算热量计内积蓄和散失热量的总和，从而求得水泥水化7天内的水化热。
Scope
This standard applies to the determination of cement hydration heat. This standard is to directly measure the temperature change of the cement mortar in the calorimeter under the condition that the temperature around the calorimeter is constant, and calculate the sum of the accumulated and dissipated heat in the calorimeter, so as to obtain the hydration heat of cement within 7 days of hydration (unit is cal/g). Note: The heat of hydration of the 7-day cement hydration period can be calculated according to the method in the appendix, but when the test results are in dispute, the actual measurement method shall prevail.
