一、疑问时刻据悉世博园区使用的道路地砖犹如人体“呼吸”器官——皮肤一样,雨天可以“吸收”雨水,热天可以“排汗”。这是什么地砖呢?二、世博会探秘这是运用了一种新型行道砖,它可以渗水,下雨天,地面上的雨水可以“钻”过地砖直接渗透人土壤,避免了地面积水的顽疾。它不积水,路面也不会反光,还能防滑,行走更加安全。三、大科学一般的混凝土与沥青等路面材料不透水、不透气。而世博会使用的可“呼吸”的地砖的主要成分是TOPCRETE(特可力),它是一种混凝土密封固化剂的顶级材料。它具有特殊处理过的沙石层,多空隙的结构使得路面上的水能迅速下渗入地下泥土。除了 First, the doubt moment It is learned that the road floor tiles used in the Expo Park are just like the human body “breathing” organ - skin, rainy days can “absorb ” rainwater, hot days can “perspiration ”. What is this brick? Second, the Expo explores this is the use of a new type of brick, it can seepage, the rainy day, the rain on the ground “drilling ” through the soil directly through the brick, to avoid the surface water Illness. It is not water, the road will not be reflective, but also non-slip, safer walking. Third, the general science of concrete and asphalt pavement material impermeable, airtight. The main component of the expansive “breathable” floor tiles used at the EXPO is TOPCRETE, the top material for concrete sealer. It has a special treatment of sand layer, multi-gap structure makes the water on the road quickly infiltrate the underground soil. apart from
