The basic level flatness strong grassroots strength C35 acid excellent resistance to abrasion and strong punching pencil hardness good color choice of specifications according to customer requirements price negotiable specimens can provide high-quality appearance Square colored concrete pavement permeable floor raw Manufacturer: Shanghai Hope stone Price: negotiable color: choose specimens: Available Delivery time: 5 days curing period: 1--2-year, color permeable floor Introduction colored permeable porous concrete floor, also known from the rubble, cement, binder, pigment and water mixing made of a porous lightweight concrete, it does not contain fine aggregate, coarse aggregate surface coated with a thin layer of cement slurry from sticking to each other uniformly distributed honeycomb cavities structure, it has a breathable, permeable and light weight, reducing environmental impact as concrete, pervious concrete research and development of more and more attention. Second, the color permeable floor / 1 pervious concrete, material composition: pervious concrete ------ special binder consisting essentially enhancer, flowing agents, stabilizers and fibers and other ingredients. It combines with the aggregate, cement, paint, etc. After mixing can greatly improve the strength of pervious concrete. While enhancing the stability and liquidity of pervious concrete, so that water permeability is better. (1) Gravel: Gravel is one of the main material pervious concrete, its quality must be controlled better. (2) Water: ordinary tap water can be used. Generally cloudy unfiltered groundwater or used unclean water can not be used (3) Cement: Portland cement to 42.5. (4) Pigment: High-quality inorganic pigments. Third, the pervious concrete road base in claim 1, pervious concrete pavement thickness: From the above reasons pervious concrete strength of color, mostly applied to sidewalks, squares, parks, gardens trail, residential roads and other places. Depending on the thickness of the surface layer different applications pavement on sidewalks, bike paths and other light load floor, generally pervious concrete thickness of not less than 8 cm; for car parks, squares and other ground in load floor, permeable concrete thickness of not less than 10 cm. 2, in order to ensure pavement structure layer has sufficient overall strength and permeability, lower surface layer of permeable base and the need for better water retention mat. Substrate requirement: compacted soil layer on the plain, equipped with the base material, the outer strength should be adequate, must have good permeability, using graded gravel or graded gravel and so on. When using graded gravel, gravel maximum particle size should be less than 0.7 times the base thickness and not more than 50mm. Cushion generally use natural gravel, particle size less than 10mm, commonly known as melon seeds, and covered with 15cm ~ 30cm thickness, laying need uniform formation. Fourth, the construction of a color pervious concrete, construction: the preparatory work on the basis of full, personnel and equipment before entering the construction. (1) for pervious concrete mixture the consistency of grout in large and small quantity, in order to ensure a uniform grout wrapped in aggregate, should adopt compulsory mixer, mixing time is longer than conventional concrete, as Pervious concrete mix relatively dry and hard before casting, roadbed must be wet with water, due to limited permeability of the concrete mixing water, if roadbed material mixing absorb some of the water, it will accelerate cement setting, reduce the use of pouring in the road, vibration, compaction and seam time, and quickly aggregate loss will weaken the bond strength between. (2) The porous concrete is dry concrete material, its initial setting quickly, usually based on the climatic conditions of the mixture control transit time, transport is generally controlled within 15 minutes, during transport, do not stop, the trolley must be stable. (3) the case of pervious concrete paving casted concrete dry material, its initial setting quickly, paving must be timely. For pavement surface, large-scale construction using sub-positions paving the way, the song spread factor of 1.1. The mixture evenly on the work surface paving, identify the flatness and control certain degree pan of water, and finally with a spatula smooth, wipe together can not have clear water with scraping feet. Similarly (4) maintenance pervious concrete and cement concrete properties, the construction of water conservation to be completed the next day, if the weather is hot and dry in 8 hours after pouring sprinkler maintenance, at least twice a day, curing time of less than three days. But direct shower water spray water of the concrete surface should be directed from the top down pressure water spray should not be used. 3, brushing transparent brightener: concrete surface to be molded and dried in about 3 days, brushing or spraying transparent brightener, enhanced durability and aesthetics. It takes too long to prevent the pores of porous concrete so that contamination and clogging. Construction process is as follows: Materials prepared by stirring transport unloading paving screed compaction received light curing cutting seam brushing brightener five, quality assurance and maintenance services company so construction floor implement 1--2 years of free maintenance (anthropogenic except for destruction). After over maintenance period, the company will charge for the cost of labor, materials and manufacturers for long-term service.
