Quality standards for sintered paving bricks

We know that sintered paving bricks have standards in size and shape. No matter which company produces the product, it is the same, but its quality is different. This requires us to understand the characteristics of sintered paving bricks. Quality standards:
The quality standards for sintered paving bricks comply with the same European quality standards. The compressive strength of solid bricks is greater than MPa. The overall water absorption rate after boiling per hour is %~%. The compressive strength of porous load-bearing bricks is greater than MPa. The compressive strength of hollow non-load-bearing bricks is greater than MPa, the weather resistance is required to meet the sub-zero freezing and thawing standards, and the bricks have accurate thermal conductivity data and other internationally accepted parameters.
The overall correspondence between physical properties is: the lower the water absorption rate, the higher the compressive strength of the material, and the stronger the wear resistance and anti-pollution ability. On the contrary, the higher the water absorption rate, the lower the compressive strength of the material. , the weather resistance and anti-pollution ability will be worse.
The relationship between the thermal insulation, sound insulation and breathing ability of the sintered paving bricks themselves, the affinity of the cement mortar, and the water absorption rate is a curve. That is, as the water absorption rate increases, these characteristics of the bricks begin to It gradually increases, and when it reaches the maximum value, it drops rapidly. This inflection point is the point at which the compressive strength and water absorption rate %. Therefore, for sintered materials, when used in ground garden landscape projects, its wear resistance, weather resistance, and anti-pollution properties must be emphasized, and its material parameters must meet the stoneware standards.
According to the above quality standards, sintered paving bricks can be divided into three, six or nine grades, so that there are products with different prices, allowing us to be more assured in use.
