Hydration properties of boron modified active belite cement concrete

In this study, hydration heat and speed of Boron Modified Active Belite (BAB) cement concretes were determined using by semi-adiabatic method.  After the development of the  theory and analysis of the BAB cement concrete production, the current work includes analyzes of hydration heat in BAB cement concrete. The same experiments were repeated in 6 different cement types including BAB cement, and their hydration properties were determined.  For samples hydration heat-time and hydration velocity-time graphs for all types of cement were prepared comparatively. Additionally in order to determine the strength properties of hydration relations, Schmidt hammer, unit weight, compressive strength tests are applied to samples and the test results are interpreted with the help of graphs. As a result, hydration properties of steam cured and non-steam cured boron modified active belite cement concrete were comparatively analyzed and heat of hydration of BAB cementitious mortar samples were found significantly lower than other types of cement. As the cause of this situation is the lack of Alite (C3S) phase and low C3A (Belit) content of boron modified active belite cement.
