Pervious stone adhesive Factory China

GENERAL

Pervious stone adhesive is a two-components modified epoxy ahesive applying in pervious concrete owing to the enhancing in mechanical and durability characteristics. Pervious concrete has many environmental benefits, such as reducing the stormwater run-off, improving the groundwater table, reducing water pollution, and mitigating urban heat island; it does not reflect light at night, so it can increase road safety and traffic comfort; it has a unique pore structure and is close to the ground covered by natural vegetation in terms of heat absorption and heat storage functions, thus, it can regulate the temperature and humidity of the urban space, alleviate the urban heat island effect; the porosity of the pavement is large, so it has sound absorption and noise reduction effectives, and reduces dust pollution; it is suitable for municipal sidewalks, bicycle lanes, garden landscapes and urban squares.

Packaging and Storage

Both components of A and B are packed in iron barrels, component A is 10kg/barrel, and component B is 5kg/barrel. The products are stored in a cool and ventilated warehouse, with a shelf life of 12 months.

Construction Process

1. Remove efflorescence or oxides on the construction base surface to make it a clean and dry.

2. According to the ratio component A:component B = 2:1 (weighing, not estimable), pour the component B material into bucket with the A component materials, and mix for 1 to 2 minutes, until it is completely mixed and uniform, forming a certain consistency adhesive.

3. Pour the colored ball millstone and adhesive into the mixer according to the ratio of 30:1, and mix well.

4. Pour the mixed base material into the construction site, use a manual scraper or a professional paver to scrape it, and fully compact it.

5. The curing time of the adhesive is 8~36 hours (depending on the temperature).

Precaution: When the using of the adhesive is finished, the plastic bucket with the remained adhesive should be sealed and stored to prevent moisture intrusion, which causes the upper layer of the glue to solidify and crust.
