Is the permeable concrete surface layer sealed with color or transparent sealing?

Permeable concrete is also called colored concrete. It is composed of stones, cement, colorant, Biocent Eco-enhancement, and dipropylene polyurethane sealant. The sealant is a spraying and sealing process after the permeable concrete is maintained. , Is permeable concrete surface sealed with color or transparent sealing? Should double-acrylate polyurethane sealing material be used for color mixing?　　Ecological Engineering has focused on Ru0026D and production of colored concrete materials and the construction of colored concrete projects for 17 years. The rich experience and scientific research tell us that the colorless and transparent dipropylene polyurethane seal cannot handle colored concrete. So, what are the footholds of our views? 　　 1. Colored concrete also belongs to the category of cement concrete, and cement, as a mixture of concrete, is wrapped on the surface of the aggregate and displayed on the surface of the road surface during mixing and paving. , And the original component of cement is lime, that is, cement is made of lime. The component of lime is calcium oxide (CaO), which reacts with water to form calcium hydroxide, which is white and solidified on the surface of concrete stones. At this time, the colorless and transparent dipropylene polyurethane sealing treatment cannot cover the calcium hydroxide, and white crystals can still be seen after the transparent sealing, which is unfavorable for the appearance of the road color effect. 2. Ecological engineering focuses on the exquisite Ru0026D and production of colored pavement materials, colored concrete construction, rich experience and scientific formulas, teaching us everything to effectively control and adjust working conditions according to actual requirements, and make high-quality and high-quality projects Inseparable from a large number of engineering practice tests.　　 Label: pe transparent sealed bone bag
