Porous Concrete Flooring Material Engineering Quotation, Construction Process of Washed Stone Retaining Walls

Porous pavement is highly practical, benefiting the benign development of the human living environment; it also plays a significant role in rainwater management and utilization, as well as in water pollution control. It is a key promotion project of the "National Construction Ministry's Science and Technology Achievements," and is widely used in pedestrian walkways, bike lanes, light rail tracks, public squares, outdoor parking lots, park pathways, and scenic roads.

Porous Concrete Binder——mainly composed of reinforcing agents, fluidifiers, stabilizers, and fibers. When mixed with aggregates, cement, and pigments, it significantly enhances the strength of porous concrete. It also improves the stability and fluidity of porous concrete, thereby enhancing its permeability.

(1) Crushed Stone: Crushed stone is one of the main materials for permeable concrete, and its quality must be well controlled.

(2) Water: Tap water is sufficient. Generally, turbid groundwater that has not been filtered or used unclean water should not be used.

(3) Cement: 42.5 Portland cement is sufficient.

(4) Pigments: High-quality inorganic pigments

Permeable Concrete Pavement Installation Advantages:

Increasing the permeable and breathable areas in cities, enhancing the heat and moisture exchange between the surface and air, regulating urban climate, reducing surface temperatures, and benefiting the alleviation of the urban "heat island" phenomenon.

(2) Maximizing the use of rainfall and snowmelt to increase the relative humidity of the surface, replenishing the increasingly depleted groundwater resources in urban areas; leveraging the permeable roadbed's "reservoir" function; improving the living conditions for urban surface plants and soil microorganisms, and adjusting the ecological balance.

(3) The solution can alleviate the burden on road drainage systems during the rainy season, significantly reducing the pollution of urban water bodies caused by heavy rain.

(4) Absorbs noise generated by vehicle travel, creating a quiet and comfortable living and transportation environment, prevents road surface water accumulation during rain and reflects light at night.

(5) To prevent road积水 and reflective glare at night, the winter will not form black ice (a nearly invisible thin layer of ice formed by frost and fog, which is extremely dangerous), thereby enhancing the comfort and safety of both vehicle and pedestrian traffic.

(6) The abundant gaps can absorb urban pollutants like dust, reducing the pollution caused by dust飞扬.

(7) Patterns and colors can be designed to suit environmental and functional requirements, fully integrating with the surrounding environment.
