The difference between Kazakh brick and fireproof brick

One of the most prominent differences between fireproof brick and Kazakh brick is the apparent difference between the two types of brick. Kazakh bricks have uneven surfaces and irregular edges, which is why they are sometimes called traditional or rural bricks. But fireproof bricks have smooth, uniform edges and a grain-like surface. In general, fireproof bricks have a more regular and modern appearance.

Kazakh brick and refractory brick are produced in two types: rustic brick and plaque. The other difference between the two bricks is their color. We’re going to look at the color spectrum of both bricks.

Difference between fireproof and Cossack bricks in terms of heat tolerance and resistance

Due to the preparation of fireproof bricks from fireproof soil and its cooking in very high temperature brick kilns, these bricks are able to withstand temperatures of 1500 ° C. In fact, these bricks have fire and heat-resistant properties. But Kazakh bricks can withstand up to 500 degrees Celsius.

When preparing fireproof bricks, the raw materials are pressed using a press machine at a much higher pressure than the Kazakh brick inside the mold. For this reason, fireproof brick has a higher resistance to pressure and is later crushed and lip-filled.

Because the raw material of the pirate brick is clay, it absorbs more water than fireproof brick. The water content of Kazakh brick is about 10%, while fireproof brick has about 5% water absorption. For this reason, fireproof bricks have higher resistance to frost and contraction and expansion than Kazakh bricks.
