Park Plaza overall appearance color ecological permeable concrete pavement floor

Park Plaza pervious concrete pavement floor color ecological overall aesthetic landscape Engineering Limited Shanghai hope stone color eco-permeable concrete floor, road construction: 1. Mixing: Floor permeable (pervious concrete mix) mixing the grout was in consistency than large and small quantities, in order to make the grout to ensure uniform wrapped in orthopedics, should adopt compulsory mixer, mixing time of 5 minutes or more. 2, pouring: permeable floor before pouring the roadbed must be moistened with water. Otherwise, rapid loss of moisture permeable floor will weaken the bond strength between aggregate. Because permeable floor mix was relatively dry and hard, the good mixing and good permeable permeable flooring floor materials laid on the roadbed can pave the way. 3, vibration: not strongly vibrated or compacted permeable floor in the casting process. Pervious concrete is generally light with a plate vibrator after vibrator pave the mix, but must be careful not to use high-frequency vibrators, otherwise it would be too dense concrete surface porosity is reduced, the impact of the permeable permeable floor effect. While the high-frequency vibrators also make cement slurry from the surface of coarse aggregate segregation out into the bottom to form an impermeable layer, so that the material loses water permeability. 4. Roll: After vibrators, should further use solid steel or light roller compaction level pervious concrete mix, taking into account the ambient temperature and other conditions consistency and mixing materials, may require multiple roll, it should be noted before rolling rolls must be cleaned to prevent the adhesive aggregate. 5, conservation: permeable floor due to a large number of holes, easy to dehydration, dry quickly, so conservation is very important. Especially early conservation, should be taken to avoid large quantities of moisture evaporation floor. Typically pervious concrete form removal time is shorter than normal concrete, so the sides and edges will be exposed to the air, the application of a plastic film or color of the cloth covering timely and side roads, in order to ensure adequate moisture and cement hydration. Permeable floor should be poured in one day after the start of sprinkler maintenance, should not use the pressure of water straight into the concrete surface watering, it will take away some of the grout, causing some of the weaker parts, but under normal circumstances directly from the Watering down. Shanghai hope stone company color eco-permeable concrete product service: 1, the company for customers to build construction project archives. 2, the implementation of the system back to the square, regularly visit customers, listen. 3, various problems such as the user's causes, I will send someone to help resolve or repair charge material cost 4, my company so construction floor implement 1--2 years of free maintenance (except for vandalism) 5, After over maintenance period, the company will charge for the cost of labor, materials and manufacturers for long-term service.
