Abstract

The invention discloses novel ecological permeable concrete. According to the permeable concrete, industrial by-products such as industrial by-product gypsum, steel slag, building waste and gravel made from tailing serve as main raw materials, the defect that traditional permeable concrete is high in production energy consumption can be overcome, the novel ecological permeable concrete is high in strength, low in cost and simple in preparing process, and does not need to be subjected to high-temperature calcination, the materials are easy to get, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to a novel ecological permeable concrete and a preparation method thereof, belonging to the field of building materials and solid waste utilization. Background technique [0002] Ordinary concrete road pavement is simple and low in cost, which brings great convenience to people's travel. However, compared with natural soil, ordinary concrete pavement lacks the ability of breathing and rainwater penetration, which also brings problems such as the drop of groundwater level to the ecological environment of the city. , land subsidence, heat island effect, urban waterlogging and a series of environmental problems. In response to the above problems, permeable concrete came into being. [0003] Permeable concrete, also known as porous concrete, is essentially a building material mixed with aggregate, cementitious material, water and additives. Its strength mainly depends on the hardened cementitious material wrapped on the surface of th...
