Permeable bricks-the more permeable the better

Different specification requirements

JC/T 945-2005 行标要求,主要技术规范 5.4 条规则 According to the requirements of JC / T 945-2005 , the main technical specifications are 5.4 rules

透水系数( 15 ≥1.0*10 -2 cm/s , 即杰出的透水性 1.1 Water permeability coefficient ( 15 ) ≥1.0 * 10 -2 cm / s , that is, outstanding water permeability

保水性不小于0.6g/cm 3 , 即孔隙率不小于25% 1.2 Water retention is not less than 0.6g / cm 3 , that is , the porosity is not less than 25%

抗冻融要求更严厉: 25次冻融循环后外观质量应契合表二要求,且抗压强度损失率不得大于20%。 1.3 The requirements for freeze-thaw resistance are more stringent: The appearance quality after 25 freeze-thaw cycles shall meet the requirements of Table 2, and the compressive strength loss rate shall not be greater than 20%.

产品质料不同 2 different product materials

     Ceramic permeable bricks adopt autogenous high-strength clinker including wear-resistant clinker, grinding wheel clinker, ceramic clinker, etc.

产品结构不同 3 different product structures

The ceramic permeable brick product has a granular structure inside, which is much larger than the capillary pores of water molecules, forming an unclosed channel in the brick, so that water can be absorbed sufficiently, and when the amount is large, it penetrates the brick body and penetrates the ground. Generally, the porosity of the brick is required to be 20-30%. The transparent porous structure is not only water-permeable, but also absorbs haze, dust, and automobile exhaust; and the micro-pores formed by the fine surface layer on the surface can effectively prevent the blockage of large particles on the pores, which is convenient for maintenance and cleaning.

Earthmoving bricks-the less permeable the better

Different specification requirements

GB/T 26001-2010 烧结路面砖国标要求,首要技能要求 5.3 规则,北方室外用路面铺装用砖须到达: According to GB / T 26001-2010 national standard requirements for sintered pavement bricks, the primary skill requirement is Rule 5.3 . The outdoor pavement paving bricks in the north must reach:

吸水率 8.0% ,吸水率过大易构成抗冻融不合格,经冬后呈现脱皮、掉渣、成粉状等现象。 1.1 Water absorption rate 8.0% . Excessive water absorption rate may easily constitute unqualified resistance to freezing and thawing. After winter, it will show peeling, dross dropping, powdering and other phenomena.

饱满系数 0.78 ,饱满系数超标会使得砖耐久性、耐候性欠好。 1.2 Fullness coefficient 0.78 . Exceeding the fullness coefficient will make the bricks poor in durability and weather resistance.

泛霜功能要求每块砖样试验后无泛霜,出产中必须配方精准合理。 1.3 Frost function requires no brick frost after each brick sample test, and the formula must be accurate and reasonable during production.

产品质料不同 2 different product materials

The main materials produced by terracotta bricks are shale, coal gangue, clay, etc., which are classified as low-temperature sintered bricks.

产品结构不同 3 different product structures

The inside of the product is mainly powdery material. After sintering, the closed micropores are formed, which do not penetrate through and have a small share. 10% The better the sintering degree, the smaller the porosity. The outdoor paving products require porosity less than 10% . Because there are certain pores on the surface, it can absorb certain moisture. Since there are no through holes in the interior, moisture cannot pass through. If moisture accumulates on the outer surface for a long time, the binding force of the outer clay layer is simply damaged under the soaking of water molecules, and the outer surface is easy to peel and fall. Affects service life. Therefore, the smaller the porosity of the clay brick, the better.
