Abstract
The belite material produced from limestone and waste silica was the s ubject of numerous investigations. In order to improve the hydraulic a ctivity, some amount of barite was added to the raw mixture. The prope rties of belite phase were studied by use of differential thermal anal ysis, calorimetry and other methods. The influence of barium on the hy draulic activity of belite has been thus confirmed. The hydraulic acti vity increase in the presence of barium depends on the stabilizing act ion of additive accompanied by the proper thermal treatment in the alp ha'-Ca2SiO4 stability range.
