Introduction of Layered Construction Technology of Color Permeable Pavement

Color permeable concrete layered pavement, mainly in order to save costs, is generally the use of plain color bottom layer of the structure. Color permeable concrete pavement is a rigid pavement structure with a certain strength and effective void ratio on the structure, and the water flow on the road surface directly permeates through the surface structure. By controlling the mixing ratio and layered construction process, the formed permeable concrete pavement can form permeable effective voids, semi-effective voids and invalid voids under the premise of ensuring the structural strength requirements. Today for you and introduce the layered construction technology of color permeable pavement.

Introduction of layered construction technology of color permeable pavement:
 
Effective voids refer to the pores with connected channels from the surface layer to the bottom layer. Semi-effective pores only have the water storage function of local "pits" and cannot make water seepage. Invalid pores are completely closed in structure, unable to connect with the external environment and unable to store and permeate water. Permeable concrete is also called porous concrete, no sand concrete, color permeable floor. It is a kind of porous lightweight concrete mixed with aggregate, cement and water. It does not contain fine aggregate, and is coated with a thin layer of cement slurry on the surface of coarse aggregate to form a honeycomb structure with uniform distribution of holes. Therefore, it has the characteristics of ventilation, water permeability and light weight.
 
Color permeable concrete layered pavement, mainly in order to save costs, is generally the use of plain color bottom layer of the structure. Color permeable concrete, surface with color permeable concrete, the general color surface layer thickness is 3-5CM, the use of 5MM particle size of the rice stone pavement. The plain bottom layer is generally paved with pea stone (commonly known as melon seed slices) with a particle size of about 10MM, which can reduce the cost very well.
 
The construction of color permeable concrete mainly includes paving, forming, surface treatment, joint treatment and other processes. Spreading can be carried out by mechanical or manual methods; forming can be carried out by flat vibrator, vibrating leveling roller, manual push-pull roller, vibrating leveling beam, etc.; surface treatment is mainly to improve the surface appearance and trim or clean the formed permeable concrete surface; the joint arrangement of color permeable concrete pavement is basically the same as that of ordinary concrete, and the contraction joint is equidistantly arranged, and the spacing should not exceed 6m.

Floor industry "high color value" products-anti-static epoxy sand self-leveling, how much do you know?

Anti-static sand self-leveling is a new type of floor coating, it has both floating sand smooth and beautiful, anti-pressure wear-resistant, light corrosion and other advantages, but also has anti-static function. It is suitable for places with high decoration, high cleanliness and antistatic requirements, such as electronics, precision instruments, chemistry, medicine, aerospace, etc., especially the production workshop and storage area of electronic instruments, integrated circuits and other components with high sensitivity to static electricity.


A brief description of the advantages and application of waterborne epoxy resin

With the introduction of environmental regulations and the awakening of environmental awareness, floor paint is a solvent-based paint with serious pollution, and VOC emissions are limited by domestic and foreign regulations. In order to meet the needs of environment-friendly and healthy life, the environmental road of the seven industries has been imperative. The "spring breeze" of the floor paint industry reform has also blown into the floor paint field, and the popularity of environmental protection products such as floor water paint has become the mainstream development direction of the industry.


Application Scenarios Overview of Waterborne Epoxy Resin

Waterborne epoxy resin refers to the epoxy resin in the form of dust, droplets, colloid dispersed in water stable dispersion system. The study of waterborne epoxy resin has been carried out abroad since the 1950 s, in which the epoxy resin is made into emulsion is a common research approach. Waterborne epoxy resins and curing agents are widely used as coatings.


Construction method for parking lot floor paint

The utility model relates to an epoxy floor, especially a parking lot floor paint construction. Epoxy floor is a kind of high strength, wear-resistant, beautiful floor, has the advantages of seamless, solid texture, good chemical resistance, anti-corrosion and dustproof, convenient maintenance, low maintenance cost and so on. Epoxy floor is widely used, parking lot floor often use epoxy floor.


Construction method and process of anti-skid parking lot floor paint

The invention relates to the technical field of construction, in particular to a construction method for anti-skid parking lot floor paint. In order to improve travel safety, some parking lots, toilets, steps, and ramps are equipped with non-slip floors to increase the friction between the soles or tires and the ground to prevent pedestrians from slipping or vehicles from slipping. However, the existing non-slip floor is expensive, and the comfort of pedestrians or vehicles is poor. Especially in rainy and foggy weather or water conditions, the anti-skid effect is poor. In addition, in the use environment of the garage, due to the weight and frequency of use of the car, cracks or peeling will appear on the surface of the floor paint, which destroys the overall beauty of the ground, and the later maintenance cost is high and there is safety.


Construction technology of parking lot floor paint

With the rapid development of real estate, more and more real estate enterprises began to attach importance to the planning and construction of underground garage, underground garage is no longer the original cement concrete. Because the construction of the underground garage is related to the image of the real estate enterprise, they all attach great importance to the beautiful and practical construction of the garage ground. For the parking lot floor paint is currently popular construction technology. The construction technology of floor paint for underground parking lot is introduced. The construction steps of the parking lot epoxy floor paint include basic treatment in the coating surface coating curing. So, epoxy floor paint primer, paint, paint how to construction?
