（资料标准： 500×250×60mm）。 Cement brick (data standard: 500 × 250 × 60mm). The benefit of this information is that it has strong compression and abrasion resistance, non-slip appearance, beautiful appearance, and relatively economical price. The other cement bricks have a dense and flat surface and are easy to construct; The appearance is slightly dirty.
（资料标准： 200×100×60mm）。 Pervious brick (data standard: 200 × 100 × 60mm). The benefit is that it is relatively water-permeable and breathable, which can reduce the "heat island effect"; there is no water accumulation on the road, which increases safety and comfort, and other Permeable bricks are relatively strong in compression and abrasion resistance and easy to construct; the disadvantage is that the appearance is slightly polluted, and it is not easily cleaned, and the surface layer is relatively loose.
Granite (data standard: 600 × 300 × 40mm). The benefits are high strength, wear resistance, beautiful colors, natural ingredients, simple cuts, and convenient construction; the disadvantage is that the price is more valuable, watertight and breathable. No information is perfect, so whether it is cement brick or not Pervious tiles , or granite, have their benefits and obvious flaws.
There is nothing best and nothing better, just choose the data you want to use based on practical needs and needs. However, in most urban outdoor projects, cement brick and Permeable bricks have a relatively large share.
