Abstract

The invention discloses a graphene enhanced water permeable brick which comprises two parts, namely, a bottom layer and a surface layer. The graphene enhanced water permeable brick is characterized in that the bottom layer at least comprises the following components in parts by weight: 16-18 parts of cement, 18-22 parts of fine sand, 50-60 parts of rock ballast and 5-6.5 parts of water; the surface layer at least comprises the following components in parts by weight: 65-80 parts of quartz sand, 15-20 parts of cement and 5-6.5 parts of water; graphene carbon materials are doped in both bottom layer and surface layer; and graphene and graphene oxide are used as the graphene carbon materials. According to the invention, the graphene is treated and then is used as a novel additive to be introduced into a water permeable brick, the graphene can be uniformly dispersed in a binding material system following water, the graphene slices have ultrahigh specific surface area and rigidity, and the Van der Waals force between the slices and the interaction between the slices and the cement grains can excellently stabilize the binding material system, can reduce the phenomena, such as, cracking and falling, and can enhance the binding effect of the binding material system, so that the overall strength of the water permeable brick can be promoted.

Description

technical field [0001] The invention relates to a permeable brick and a preparation method thereof, in particular to a graphene-enhanced permeable brick and a preparation method thereof. Background technique [0002] Permeable bricks originated in the Netherlands. With the increase of urban population, groundwater resources are becoming increasingly scarce, and some areas have subsided and caused seawater backflow. In order to make rainwater replenish groundwater in time, the Dutch made a small pavement brick of 100mm×200mm×60mm. On the street pavement, a 2mm gap is reserved between the bricks so that when it rains, the rainwater will seep into the ground from the gaps between the bricks. This is the famous Dutch brick. Time has entered the 21st century, and the domestic urbanization process is accelerating, and many cities are facing the risk of groundwater depletion. In order to realize the coordinated development of urbanization and natural resources and environment, pro...
