Low temperature dolomitic ceramics

New building material composed of clay and dolomite at the variable mass ratio C D = 1/9−9/1 is developed. At the firing temperature of 720 °C the interaction between the components takes place resulting in the formation of structure which ensures high mechanical strength of the material obtained. The structure is composed of both the ‘old’ structure of carbonates and new formations such as calcium silicates, calcium aluminates and MgO in fine crystalline or amorphous state permeating through the ‘old’ structure. The mechanical strength of the fired material subjected to hydraulic hardening with following drying increases per 200–300%.
