Shenzhen, Hainan, Guangxi and Yunnan color permeable flooring, glue permeable stone floor price of Guangxi color permeable floor, Shenzhen permeable flooring, flooring permeable Yunnan, Hainan and permeable flooring, color permeable floor price, pervious concrete, permeable rock viscose floor price, the manufacturers hope stone wholesale special! A color permeable concrete floor (also known as permeable floor) is a new type of environmentally friendly flooring, permeable ground with approximately 20% of the pore, when it rains can quickly add urban groundwater resources and to absorb vehicle noise, pervious concrete pavement surface reflecting sunlight to reduce heat, reduce surface temperature, reduce the "heat island effect." Color permeable floor also provides filtering effect and avoid automotive and industrial emissions of heavy metals, such as tire wear and industrial dust directly into the river. Permeable flooring, color permeable flooring, eco-permeable flooring, eco-permeable concrete, pervious concrete, permeable concrete floors, colored pervious concrete, stone manufacturers supply Shanghai hope! Shanghai hope to provide permeable stone floor price, the price of pervious concrete, ecological permeable floor price; throughout the country to undertake permeable floor construction, pervious concrete, permeable colored floor construction; construction technology skills, create professional-quality Chinese permeable flooring industry first a brand! 15901786543 Miss Lee, welcome your advice! Second, pervious concrete advantages:? When concentrated rainfall can alleviate the burden of urban drainage facilities to prevent river flooding and water pollution. l ?? allow rainwater into the ground quickly, restore groundwater to maintain soil moisture. l ?? prevent surface water, not reflective at night to increase road traffic safety and comfort. l ?? adjust the temperature and humidity of urban space, improve urban heat circulation, relieve the heat island effect. l ?? large porosity can reduce road noise when driving the vehicle, creating a comfortable traffic environment. l ?? cities can absorb a lot of voids contaminants (such as dust) and reduce dust pollution. l ?? easy to maintain, the gap will not be damaged, easy to plug. l ?? designs as needed, to fully combine with the surrounding environment. l Third, the mechanical properties of pervious concrete physical: ??? ?? ??? permeable concrete compressive strength (MPa) ?? 20 ~ 45 ??? flexural strength (MPa) ?? 2.0 ~ 5.0 ??? relative density of 1.95 to 2.05 ??? ?? porosity (%) 15 to 30 ??? ?? permeability coefficient (mm / s) ?? 1.5 ~ 15.0? CONCLUSIONS ??? (1) the strength of pervious concrete without sand and cement content and water-cement ratio related to the same particle size of aggregate concrete mixing and no sand, there is an optimal amount of cement and water-cement ratio. ??? (2) for different size aggregates, in the same amount of cement, aggregate size is not small, concrete strength. ??? (3) non-sand concrete porosity, permeability decreases with increasing the amount of cement and large diameter slightly smaller than the diameter. No sand concrete permeability and porosity have better connectivity correspondence. ??? (4) the use of unilateral amount of cement, gravel and 300kg respectively, the amount of 1400kg, stone size of 5mm ~ 8mm, add a certain proportion of binder and antifreeze can be obtained by compressive strength 20MPa, flexural strength 3.1 MPa, 15% porosity, permeability coefficient permeable concrete 1.9mm / s, and successfully applied in municipal engineering, and achieved good social benefits, the construction unit of praise.
