Purpose and principle

This instrument is designed according to the relevant provisions of the national standard GB/T12959-2008 "Method for determination of cement hydration heat". Suitable for the determination of hydration heat at any hydration age of medium heat silicate cement, low heat slag silicate cement, ordinary silicate cement, slag silicate cement, volcanic ash silicate cement, fly ash silicate cement, etc. This instrument can also be used for other types of cement when the dissolution heat method is specified for determining the heat of hydration.
