The advantages and introduction of clay bricks

Date:2020-02-18 11:34 | From:Zhengzhou Sunrise Refractory | Author:admin
Clay bricks are artificial small blocks used in construction. Also called sintered brick. Solid clay brick is one of the oldest building materials in the world. From the tomb of Qin Shihuang in Shaanxi to the Great Wall of China in the Ming and Qing Dynasties, it has passed down the history of Chinese civilization for thousands of years. To this day, it is still a beloved building material.
China's clay bricks generally have an Al2O3 content of more than 40%, and an Fe2O3 content of less than 2.0 to 2.5%. The clinker in the ingredients is 65-85%, and the combined clay is 35-15%. The comminuted combined clay and the ground clinker are mixed and ground together, and then mixed with the granulated clinker to form a semi-dry mud, which is formed under high pressure and fired at about 1400 ° C. The performance is better.

Clay bricks are weakly acidic at high temperatures, and their resistance to alkaline slag erosion is slightly worse, but they increase with increasing Al2O3 content. Thermal stability is better than silicon brick, magnesium brick (see magnesia brick), etc.
Qualified blast furnace clay bricks are dried and treated with vacuum phosphoric acid impregnation and phosphoric acid impregnation products fired at low temperature for the second time.
