If you are looking for customized and cheap brick to paving in the park made in China from a brick to paving in the park factory, Zibo Qunhui Refractory Co.,Ltd is always at your service.Description  This brick lowers the surface temperature of the ground by a retaining water effect with an water retentivity brick.This brick cools down in midsummer.Feature  1)Water retentivity : High moisture retaining efficiency as 17L/m2 and keeping the condition in a long duration.  2)Water absorbability : 100% watar absorbing efficiency and keeping the condition in a long duration.  3)Water infiltration ability : Water infiltrating through efficiency is as the same as soil and there remain little puddles after scattering water on it.  4)Ecology : 100% recycle product used industrial waste.Lower heat-island phenomenon  1)Moisture retainability makes sprinkle water effect more efficiency , and then hastens the heat of vaporization to turn down the temperature rising up caused by heat-island phenomenon.  2)Water absorbability is useful to absorb water from the ground, therefore it keeps the moisture retaining condition in a long duration even under sunny weather.  3)The surfacetemperature is 15-20°C lower than asphalt on the midsummer day.Data of the performanceItemsMOISTPAVEStandard of JapanWater retenntivity0.30g/cm3over 0.15/cm3oWater absorbability100%over 70%oWater infiltrationability10-4cm/s-oAnti-bending strength5.6N/mm2over 3N/mm2 (P)oover 5N/mm2 (R)oAnti-slip resistance80BPNover 40BPN (P)oover 60BPN (C)oAnti-abrasion resistance5.6N/mm2over 5N/mm2oCompressing strength25.0N/mm2over 17N/mm2 (P)oover 32N/mm2 (R)x*Remark : P=Pavement  : R=Road  : C=Car parking*The quality and safety of products are according to the standard of Japan.
