Exposed Aggregate Permeable Concrete and Colored Permeable ConcreteFlooringBoth are commonly referred to as pervious concrete, but there are still certain distinctions between the two. There are two types of pervious pavements: one is high-bearing aggregate pervious concrete, and the other is colored pervious pavement.
Color-permeable paving is used forCementColor-bound materials, aggregates, water, etc., mixed in a specific ratio, form a permeable paving surface that is directly laid on-site. Exposed aggregate permeable concrete is a type made with natural colored stone aggregates, mixed with cement, binder, and water, through a specific mixing process, combined with a seriesSurface TreatmentAgent, a natural stone flooring system that washes away the cement surface using a special process.
Asphalt concrete pavement informationGardenLandscape journey andFoamPreferred ground material for permeable paving in urban construction, this innovative paving method combines artistry, aesthetics, and functionality. It infuses the city's pavements with art and vitality while allowing rainwater to seep into the ground, effectively eliminating surface puddles. It is a decorative ground material that "breathes."
Methods for cleaning permeable concrete paving with exposed aggregates
Apply the mixed retardant slurry directly and evenly to the un-set permeable aggregate concrete surface using a paint sprayer (true stone paint sprayer is also acceptable). Achieve uniform coverage without any missed spots. The application can be adjusted flexibly according to the required depth and construction temperature as needed.
2. After the aggregate below the surface has reached the specified strength, use a high-pressure water jet to wash away the unhardened surface concrete. The flushing time is generally completed within 8-48 hours after spraying, with the water jet pressure being appropriate and avoiding vertical washing.
3. After spraying cleaning agent, the surface must be covered with a double layer of film and geotextile to prevent direct sunlight exposure.
If unfamiliar with the initial operation, to prevent overspray, you can add an appropriate amount of pigment to the cleaning agent material to facilitate identifying uneven coating areas.
The permeable concrete with exposed aggregates can achieve strengths up to C25-C30, making it perfectly suitable for vehicle and pedestrian traffic. Moreover, its daily maintenance is simple, requiring only routine water rinsing.
Porous concrete is a new product developed based on ordinary concrete, marking a new direction in the development of concrete. It retains the physical properties of ordinary concrete while imparting new meaning to it. In the near term, it can be widely used in public squares, sidewalks, bike lanes, residential roads, parkways, campus roads, outdoor parking lots, and factories. It can also be applied to the cushioning layer of permeable block paving structures.
