What is low porosity clay brick?

Low Porosity Clay Brick – This is a variety of refractory material, which is characterized by low porosity, that is, the number of pores inside the brick body is relatively small.

Introduction of Low Porosity Clay Brick

Clay bricks with less pores 18% belong to clay bricks with low porosity. Types of low porosity clay bricks have porosity 16%, 12%, 15% And 10%. The lower the porosity, the higher the price. Low porosity clay bricks are mainly made from clay and sintered at high temperatures.

Features of Low Porosity Clay Bricks

Low porosity clay brick has high strength, high fire resistance, highly compact, low porosity and good thermal shock resistance. Low porosity brick is resistant to rapid cooling and heating, as well as erosion, especially acidic. Because low porosity clay bricks are resistant to cracking, they are often used in glass furnace regenerators.

Low porosity clay brick production technology

Low porosity clay brick is made using traditional clay brick production technology, which contains burnt precious stones, sintered clay and other raw materials, mixed in a reasonable ratio, and then molded under high pressure and sintered at high temperatures.
However, the firing temperature is approximately 30°C higher, than clay bricks. Low porosity low porosity clay bricks mainly rely on fired stones to line the pores. After adding fired rocks, low porosity clay bricks become dense, durable and resistant to erosion several times compared to conventional clay bricks.

Difference in porosity between clay brick and low porosity clay brick

The porosity of clay bricks is usually 24-26%, while low porosity clay bricks are mainly used in the range 12-16%, and bricks with porosity are also available 10%. Low porosity clay bricks are used to make the most important parts (10%).
