Product introduction

   The determination of heat of hydration is based on the gas law of thermochemistry, that is, the thermal effect of chemical reaction is only related to the initial state and final state of the system, and has nothing to do with the reaction path. It is proposed that under the condition of constant temperature around the calorimeter, the unhydrated cement and the hydrated cement of a certain age are dissolved in a certain concentration of standard acid, and the difference of the heat of dissolution measured is that the cement meets the requirements The heat of hydration released during the age. Cement hydration heat detector is mainly used to determine the hydration heat of cement before and after hydration The heat of hydration of cement at any age is determined by the difference between the heat of dissolution in the standard acid of concentration.

Executive Standards

   Product compliance GB/T12959 -2008 determination method of cement hydration heat Standard requirements. It is suitable for the determination of hydration heat at any hydration age of medium heat Portland cement, low heat Portland slag cement, ordinary portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement, etc.
