Tianjin 5cm Permeable Concrete Pavement Surface Construction Technique Pamyia Economical and Eco-friendly Permeable Concrete

Permeable concrete paving, as a new urban paving method, allows rainwater to infiltrate underground through the paving structure via large-pored structural layers or drainage permeation facilities, thereby controlling surface runoff and promoting rainwater utilization.

Permeable concrete reinforcing agent is a new type of green and environmentally friendly material that participates in the cement hydration reaction to form a high polymer cement hydration body. It increases the thickness of the paste on the stone surface, significantly enhancing the compressive and bonding strength of the cement hydration body, and greatly improves the concrete's frost-thaw resistance, durability, and weather resistance. The inorganic color powder variety is comprehensive, widely used, with vibrant colors, strong coloring power, high hiding rate, good dispersion, and excellent weather resistance.

Porous concrete flooring is an excellent paving material for protecting groundwater, maintaining ecological balance, and alleviating urban heat island effects. It holds special significance for the positive development of the human living environment, urban rainwater management, and water pollution control. As early as the 1970s and 1980s, the United States began researching and applying porous concrete, with many actively promoting its use. For instance, Germany aims to transform 90% of its roads into porous concrete within a short period, changing the past ground coverings that destroyed urban ecosystems, and allowing the porous concrete roadways to rely on their extensive social benefits.
