Water permeable concrete and manufacturing method thereof

Abstract

The invention discloses a pervious concrete and is characterized in that the pervious concrete is made by mixing cement, aggregate, water, water reducer agent and adhesive evenly; and the cement, the aggregate, the water, the water reducer agent and the adhesive are mixed in different weight proportions of 1-1.2 to 5.5-8.5 to 0.2-0.5 to 0.01-0.2 to 0.01-0.2. The invention can solve the natural ecology problems of hardened ground in cities, atmospheric circulation as well as soil and water moisture retention, thereby forming a high-quality natural ecology environment and maintaining urban ecological balance. The pervious concrete consists of two pervious surface courses and two macadam bases in different particles so as to provide a water storage structure which can store the water until the water penetrates into the soil; meanwhile, the invention can be made into building block, which can be provided with different decorative patterns and colors on the surface, and has the advantages of artistic quality, water permeability, good water retention, skid resistance, high strength, cold resistance and weather resistance, etc.

Description

Technical field: [0001] The invention relates to the technical field of buildings, in particular to a method for making permeable concrete. Background technique: [0002] With the continuous prosperity and development of the world economy, the human earth is also in the process of development, changing its original appearance. The rapid development of urban construction, public buildings, residential buildings, and road construction harden the surface environment, which almost completely changes the ecological environment of the construction site. The atmospheric evaporation cycle is affected, resulting in lower air humidity and higher temperature in the urban area. This "heat island effect" is causing changes in the natural environment and vegetation. In summer, the city is more sultry, and it is easy to form a "heat island effect" to increase the dust in the atmosphere. People feel more and more uncomfortable in life, threatening human health. The hardening of the ground ...

AI Technical Summary

Problems solved by technology

[0003] 1. Sewage is directly discharged into urban rivers and lakes, causing a large amount of clean surface water to become sewage and lose its use value;

[0004] 2. The natural environment of urban surface water is destroyed, the wetland area is reduced, and the river course is hardened, etc., which changes the water ecology and the water loses its self-purification function;

[0006] 4. Excessive exploitation of groundwater by industry and residential groups leads to a drop in groundwater levels and ground subsidence, threatening urban buildings;

[0007] 5. The hardening of the road surface prevents rainwater from penetrating into the ground, and the accumulation of water on the ground affects urban sanitation and traffic, or after a heavy rain, the amount of water flowing into the sewer increases greatly, which adds a huge processing burden to urban drainage pipes and sewage treatment plants

On the traditional hardened road surface, because a large amount of rainwater cannot penetrate into the ground in time, a large amount of rainwater flows into the river through the city, increasing the flow of the river, thereby increasing the possibility of river flooding. On the one hand, the overflow of ...
