Cement Hydration Heat Testing Analytical Service

Overview

The heat released when cement reacts with water is called hydration heat and is expressed in joules per gram (J/g).

From the perspective of heat evolution rate, the cement hydration process can generally be divided into three stages:

1. The first stage, referred to as the dormant period, occurs when cement particles initially come into contact with water and react, resulting in a rapid heat release. However, due to the presence of gypsum, a passivation layer forms on the surface of the cement particles, reducing the heat release rate.

2. The second stage, known as the phase-boundary reaction stage, is when the heat release rate of cement hydration reaches its peak, and the growth of cement particles accelerates significantly.

3. The third stage, called the diffusion control stage, is characterized by the gradual thickening of hydration products accumulating on the surface of the cement particles. During this phase, the heat release rate of cement hydration decreases, and the reaction becomes controlled by diffusion.
