Permeable floor color eco-permeable permeable floor floor construction diagram: material preparation → mixing → Transport → Uninstall → paver leveling → → → Maintenance → light compaction closing kerf → brushing color brightener permeable floor permeable floor eco-permeable floor physical and mechanical performance parameters are as follows: Porosity: about 20% relative density: about 2.0 permeability coefficient: more than 2MM / sec 28 days flexural strength: more than 4.5MPa 28-day compressive strength: more than 25MPa mixing ratio: Every 50 kg permeable floor material plus 2.2 kg of water permeable floor color eco-permeable floor permeable floor of technical indicators into mixture has hardened concrete targets and indicators. (1) mixing thereof: slump (5mm ~ 50mm); setting time (initial setting less than 2h); slurry level package (package evenly hand gripping into the group, with a metallic sheen). (2) Curing Concrete: Strength (C15 ~ C30); permeability (no less than 1mm / s); porosity (10% to 20%). (3) freeze-thaw cycles: generally not less than D100. Color permeable floor is a new environmentally-friendly materials, through the rational ratio, finished construction of the finished product has a porosity of about 20%, rain (snow) water can quickly add urban groundwater resources, due to surface roughness, can absorb noise vehicles can reduce ground reflected sunlight and heat, reduces surface temperature, reduce the "heat island" effect, increasing walking comfort and safety.
