Pervious concrete factory outlets

Pervious concrete material pervious concrete reinforcing binder pervious concrete, permeable floor, permeable pavement, coloring agents, binders, factory direct Jing Shi pervious concrete is a form of lightweight aggregate concrete, it has a certain strength and bonding resistance, can be made into a variety of desired shapes, the molding itself can also be combined with the concrete molding. Sand Concrete is an aggregate of coarse aggregate particles, each particle being approximately 1.3mm thick slurry wrapped in a thin layer. Therefore, there is a lot of internal concrete pores, pore size and grain size of coarse aggregate approximately equal, the water can flow in the pores, so no sand concrete is a good permeable material. Further, due to the larger pore size, capillary action so little water. Pervious concrete because there is no fine aggregate, the total surface area of ??the aggregate is much smaller than ordinary concrete, cement consumption for wrapping aggregate also decreased, so no sand concrete density is much smaller than ordinary concrete. Due to the low amount of cement, and no fine aggregate concrete without sand itself is relatively low cost. In addition, no sand concrete coarse aggregate can be used gravel, ceramic can also be used slag and other industrial waste, construction waste and even higher strength, such as broken bricks, broken concrete blocks, etc., and after the old broken concrete without sand , and it is a good coarse aggregate. Thus, not only the cost of pervious concrete can be reduced and the use of local materials, old building demolition waste, etc. after the problems can be more satisfactory solution. Because less fine particulate material, simplifying the transport and site management program. And when there is no sand concrete pouring, blanking can be molded by gravity, without plug pound, very convenient technical level of workers demanding construction.
