[Pervious concrete method and construction steps]
【十大菠菜导航网址】:The viscosity of the cement slurry in the pervious concrete mixture is relatively large and the amount is small. In order to facilitate the cement slurry to be evenly wrapped on the aggregate, it is appropriate to use a forced mixer, and the mixing time is more than 5 minutes。
【十大菠菜导航网址】:The subgrade must be moistened with water before pouring。Otherwise, the rapid loss of water in pervious concrete will reduce the bond strength between aggregates。As the mixer is relatively dry and hard, it is necessary to smooth the pervious concrete material on the roadbed。
【十大菠菜导航网址】:It should not be strongly vibrated and tamped during the pouring process。
【十大菠菜导航网址】:After vibration, solid steel pipe or light roller should be further used for compaction, flattening, pervious concrete mixer, considering the consistency of the mixer and the surrounding temperature and other conditions, it may be necessary to roll several times, and the roller must be cleaned before rolling to prevent bonding aggregate。
【十大菠菜导航网址】:Due to the existence of a large number of holes, pervious concrete is easy to lose water and dry quickly, so the maintenance is very important。
【十大正规网赌网址】:The film coating wet curing time of pervious concrete shall not be less than 7 days, and then a layer of special sealing agent for pervious concrete shall be sprayed to make the appearance effect tend to ******。

Color pervious concrete material details    
1.Color material 2.Permeable concrete binder 3.Sealing agent is composed of three materials。

Scope of application:
1. Municipal engineering: streets, sidewalks, road dividers, theme parks, cultural squares, landscape engineering。
2, Commerce: business building, hotel, restaurant, bar, large ******, exhibition center, supermarket, shops, parking lot。
3. Residence: apartment, villa, residential area, courtyard, garden。
4, places: parks, playgrounds, water pools, swimming pools。
5, others: industrial plants, schools, kindergartens, bus system platforms, real estate inside and outside decoration。

Color pervious concrete:
With high bearing capacity and integral molding pavement, its anti-settlement performance is better than that of general permeable bricks, and it can reach the concrete bearing standard above C25。
1, water permeability, 15%-25% of the void rate, water permeability up to 270 liters/square meters/minute。
2, porous surface, large area application can reduce urban noise。
3, good gas, alleviate the urban heat island effect。
4, no water, no snow in winter surface is not easy to freeze。
5, effectively supplement groundwater, conducive to plant growth。

Preparation and construction of pervious concrete:
 1, construction: on the basis of adequate preparation, personnel and equipment can enter the construction。  
  The consistency of cement slurry in pervious concrete mix is larger,And the quantity is small,In order to make the cement slurry can ****** evenly wrapped on the aggregate,It is advisable to use a forced mixer,The mixing time is longer than that of conventional concrete,Because the pervious concrete mix is relatively dry and hard,Before pouring,The subgrade must first be moistened with water,The reason is that the amount of mixing water in pervious concrete is limited,If the subgrade material is absorbing part of it mix the water,*** will accelerate the setting of cement,Reduce the time spent on pavement pouring, vibration, compaction and jointing,And rapid water loss will weaken the bonding strength between aggregates。  
  Pervious concrete is a dry concrete material, its initial setting fast, generally according to the climate conditions to control the transport time of the mixture, transport is generally controlled within 15 minutes, do not stay in the transport process, the cart must be stable。  
  (3) paving casting molding  
  Pervious concrete is dry concrete material, its initial setting fast, spreading must be timely。For pavement surface, large area construction adopts silo paving, and its loose paving coefficient is 1.1。Spread the mixture evenly on the working surface, use the scraper to find the flatness and control a certain degree of flooding, and wipe it with a spatula after the first use, wipe no clear water。    
  Pervious concrete has similar properties to cement concrete. Water curing shall be carried out ****** days after the construction is completed. If the weather is hot and dry, water curing can be carried out 8 hours after pouring, at least twice a day, and the curing time shall not be less than 3 days。However, it is not appropriate to use pressure water directly to shower the concrete surface, and water should be sprayed directly from the top down。  
  3, brush transparent brightener:  
  After the surface concrete is formed and dried in about 3 days, brush or spray transparent brightener to enhance durability and aesthetics。Prevent the pervious concrete pores from being polluted and blocked over time。
