1. Distinguish from the weight of clay refractory bricks: this can be weighed with an electronic scale. The weight of good quality clay refractory bricks is about 3.65KG, and the weight of average quality clay refractory bricks will be less than 3.65KG.
2. Distinguish from color: Good quality clay refractory bricks are mostly light yellow, brownish yellow, and uniform in color. Quality-like clay refractory bricks are lighter in color.
3. Distinguish from appearance: Clay refractory bricks generally consist of a small number of black spots and are evenly distributed. The black spots represent iron oxide impurities. The more black spots, the more impurities, the refractory is not high enough; Whether the surface of the clay refractory bricks is smooth. Good clay refractory bricks are smooth to the touch, no cracks, no rolling, ordinary clay refractory bricks are rough to the touch, and some even have large cracks. Cracked clay refractory bricks have low compressive strength and are easily eroded by harmful gases. Therefore, this type of clay refractory bricks cannot be used in the main parts of buildings.
4. Distinguish from the physical structure: Good quality clay refractory bricks have clear structures and sharp edges and corners. There are no corners or edges. The edgeless clay refractory bricks will greatly reduce the strength of the masonry wall and affect the quality of the entire project.
