Introduction of Kerui Fire Clay Brick for Kilns
Clay bricks refer to clay products with Al2O3 content of 30% ~ 48% aluminum silicate materials. Clay bricks are made of 50% soft clay and 50% hard clay clinker, according to certain particle size requirements, and after molding and drying, they are fired at a high temperature of 1300~1400°C. The mineral composition of clay bricks is mainly kaolinite and 6%~7% impurities.
Compared with ordinary clay bricks, Kerui clay bricks uniform and fine raw materials and add appropriate auxiliary materials as well as some additives. In addition, these high-quality raw materials are subjected to steps such as precise batching, mixing and high-pressure molding. At appropriate sintering temperatures, these raw materials will transform into the mullite crystalline phase. These are the important reasons for the superior performance of Kerui fire clay bricks.
With good raw materials and advanced production technology, Kerui clay bricks have high refractoriness, low porosity, excellent high temperature creep performance and good stability.

Key Points About Construction of Clay Fire Bricks
- Workers should keep the base compacted and leveled. When using mortar as the bonding layer, wet the surface of the base by sprinkling water.
- There are two laying methods: flat laying and side laying. Laying patterns include straight, diagonal, and herringbone.
- When using a sand-cement bonding layer, evenly spread and compact the sand, avoiding frozen sand. The thickness should be 15-20 millimeters. When using a 1:3 lime mortar bonding layer, the thickness should be 10-15 millimeters. Before laying, soak the bricks in water, and the mortar consistency should be 30-35 millimeters.
- For diagonal and herringbone laying, process the edge row of bricks at a 45-degree angle and connect closely with the wall or other surfaces.
- The brick joints are generally 2-3 millimeters wide and should not exceed 5 millimeters at most. The staggered joints between adjacent rows should be 1/3 to 1/2 of the brick’s length.
- For brick floors using mortar bonding layers, workers can fill the joints with a thicker 1:3 lime mortar. For brick floors using sand-cement bonding layers, it’s good to use sand to fill up to half the height of the joint and then finish the following with mortar. Before filling joints, wet the surface and tap it down firmly.
- After joint filling, allow a minimum of 3 days for proper curing before walking on the surface.
