CRYSTALLIZATION KINETICS OF CALCIUM HYDROSULFOALUMINATE DURING HARDENING OF MIXED HIGH-STRENGTH CEMENT.

The work indicates based on the results of chemical, radiographic and differential thermal analyses – it can be concluded that additional introduction of CaSO4 into the composition of high-strength cement contributes to a more intense crystallization of ettringite only on the first day of hardening, with time this process slows down, and the amount of ettringite does not increase.
