Abstract

The invention discloses environment-friendly pervious concrete. The environment-friendly pervious concrete is characterized in that the environment-friendly pervious concrete comprises the following components in parts by weight: 20-30 parts of cement, 0.5 to 1.5 parts of aluminum oxide nanotubes, 2 to 5 parts of N-(trimethoxysilyl propyl) ethylenediamine triacetic acid ammonium salt modified nanoaluminum powder, 60 to 70 parts of rough aggregate, 0.5 to 1.5 parts of nano porous hollow cage-shaped titanium oxide, 1 to 2 parts of porous polysaccharide microspheres, 0.1 to 0.4 part of sodium sulfonate-based hyperbranched poly (amine-ester) and 20 to 30 parts of water. The invention further discloses a preparation method of the environment-friendly pervious concrete. The environment-friendlypervious concrete disclosed by the invention is excellent in mechanical property, good in fatigue resistance and water permeability, good in comprehensive performance, wear resistance and durability,and safe and environment-friendly to use.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly permeable concrete and a preparation method thereof. Background technique [0002] With the rapid development of our country's economy and the continuous acceleration of the pace of modern urban construction, the urban ground has gradually been covered by buildings and concrete pavement, rainwater cannot be infiltrated and collected, the land cannot breathe, and environmental problems are becoming more and more prominent. , has brought environmental impacts such as heat island effect and groundwater level drop to the city. Due to the impermeability of urban roads and the lack of drainage system functions, the phenomenon of urban waterlogging is increasing day by day. In severe cases, traffic paralysis is caused, and the safety of life and property is threatened. There are many cases of urban cars and people being flooded by heavy rain every summ...
