Problems solved by technology

And because the rainwater cannot penetrate into the ground through the road surface, the rainwater is discharged from the municipal sewage pipe network, which increases the load of the municipal drainage system
[0003] At present, my country has mainly carried out research on paving sidewalks with permeable concrete bricks, while paving roads using domestic materials and construction techniques, squares have not yet reached the level of practical application

Abstract

The invention provides a water-permeable pavement material and belongs to the technical field of building materials. The water-permeable pavement material comprises: by weight, 12 to 15% of ordinary portland cement, 10 to 12% of quartz sand, 15 to 20% of construction waste aggregate, 1 to 2% of a water reducer, 15 to 20% of coal ash, 4 to 8% of steel slag, 8 to 12% of rubber powder, 12 to 15% of glass fibers, 10 to 15% of broken stones and 5 to 9% of diatomite. The water-permeable pavement material has good water permeability and high strength, adopts waste building materials, reduces a cost, is suitable for pavements, piazzas and parks made of water-permeable concrete and can adjust urban microclimate and keep an ecological balance.

Description

technical field [0001] The invention provides a permeable pavement material, which belongs to the technical field of building materials. Background technique [0002] At present, roads and squares in cities and towns in my country are mostly paved with traditional asphalt and concrete materials. However, most of these roads are impermeable, and after the rain, the rainwater will be intercepted by the roads; in addition, due to the long-term excessive exploitation of underground water resources in various cities, the urban groundwater level has dropped significantly. The subsidence of the ground due to the drop of the groundwater table occurs from time to time. And because the rainwater cannot penetrate into the ground through the road surface, the rainwater is discharged from the municipal sewage pipe network, which increases the load of the municipal drainage system. [0003] At present, my country has mainly carried out research on paving sidewalks with permeable concret...
