Exposed Aggregate Permeable Concrete

1. What is exposed aggregate permeable concrete?

Exposed aggregate permeable concrete is called a permeable pavement that does not fade. In order to make the permeable pavement more beautiful and prevent problems such as fading caused by spray-painted permeable concrete, colored stones can be used instead of ordinary stones. After surface treatment of the colored permeable pavement using concrete surface retarder, it is washed with a high-pressure water gun, but the aggregate is actually exposed to the outside.

2. What is the principle of exposed aggregate?

The water permeability principle of exposed aggregate permeable concrete is similar to that of permeable concrete. The aggregates are specially graded to form a honeycomb structure, or a popcorn candy structure. Therefore, it has a certain strength and certain water permeability and is a high-end decorative type. Its color and texture are determined by the exposed colored aggregates. In addition to using the colored strong permeable concrete construction technology, its construction also requires evenly spraying surface coagulants on the surface of the wet exposed aggregate permeable concrete that has just been completed, and washing operations with appropriate water pressure within a suitable time.

3. What are the advantages of exposed aggregate permeable concrete?

Meet the relevant requirements for various bearing capacities

Because it is paved as a whole, compared with other pavements, natural exposed aggregate concrete pavement has a strong bearing capacity and excellent settlement resistance. In actual use, appropriate materials and thickness can be selected based on the differences in road grades to ensure that the bearing capacity meets the requirements.

High traffic safety factor

Because exposed aggregate permeable concrete is a pavement with large porosity, the water permeability effect is remarkable. Even in rainy days, rainwater can be drained out in time to reduce road slippage and ensure safe passage of vehicles.

Energy saving and environmental protection

Exposed aggregate permeable concrete itself has a certain adsorption effect, which can effectively absorb dust, impurities, etc. present in the air and reduce the content of dust in the air. In addition, the materials used in the pavement are also environmentally friendly and have minimal impact on the environment.

Good landscape effect

Looking at many urban roads, it is not difficult to find that the color of the road surface is relatively simple, while the natural exposed aggregate permeable concrete pavement is a material with diverse colors. It can not only increase the service life of the road, but also add a bright look to the city. landscape.

Strong frost resistance

The frost heave resistance test of the exposed aggregate permeable concrete showed that the pavement has good frost heave resistance and will not cause frost cracks and other undesirable phenomena on the pavement due to excessive cold in winter.

Stable performance

Exposed aggregate permeable concrete itself also belongs to concrete. In addition to the above characteristics, this pavement also has the related characteristics of ordinary concrete, such as stable performance and high strength.

4. Main uses of exposed aggregate permeable concrete

We can see that exposed aggregate permeable materials are used in various fields in life. Common ones are garden roads, activity centers, parking lots, municipal roads, sidewalks, large squares, passenger lanes, bus stops and other places. Using the color, shape and ever-moistening luster effect of natural stone, the surface aggregate can achieve a natural, non-artificial paving effect. It is a pavement material that not only has good looks but also improves the driving safety factor. Very popular in the market.
