不同水化热测试方法对复合胶凝体系测试结果的分析研究

Analysis Study of Different Hydration Heat Methods on Tested Results of Composite Gelation System

选用溶解热法和TAM AIR热导式等温量热仪测试法对粉煤灰、矿渣粉不同掺量的复合胶凝体系进行了水泥水化热测试试验。试验结果表明,较溶解热法而言,TAM AIR测试法测试精度高、试验误差小,能精确测量水泥基胶凝材料水化放热,适用于复合胶凝体系水化放热测试试验。

The test of cement hydration is carried out on the composite cementitious system with different content of fly ash and slag powder by using the method of dissolution heat and TAM AIR thermal conductivity isothermal calorimeter.The results show that the TAM AIR test method has higher testing accuracy and smaller test error than the dissolution heat method, and can accurately measure the hydration exotherm of cement-based cementitious materials, which is suitable for the hydration exothermic test of composite gelling system.
