Cavernous garden waste concrete

Abstract

The invention discloses a concrete and a preparation method thereof. The concrete comprises cement, sand, stone, and garden wastes. Preferably, the garden wastes are fragmented garden wastes after grinding. The concrete is prepared by evenly mixing cement, sand, stone, fragmented garden wastes and water according to a weight ratio of 100:90-150:190-250:5-40:45-60. The garden wastes generated during the city construction process are recycled, and the wastes are converted into valuable resource. The concrete has the advantages of good water absorbing performance, water permeability, breathability, and high strength, and can be applied to parts that do not have high requirements on strength. Moreover, the raw materials are easily available, the preparation method is simple, and the preparation cost is low.

Description

technical field [0001] The invention relates to the field of building materials, in particular to concrete, in particular to spongy garden waste concrete. Background technique [0002] With the continuous prosperity and development of the world economy, the earth has gradually changed its original appearance. Urban construction is changing with each passing day and developing rapidly. The construction of public buildings, houses, and roads hardens 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, forming a "heat island" effect". This "heat island effect" makes the city hotter and hotter in summer, and the dust in the atmosphere increases, making people's life more and more uncomfortable, threatening human health, and the hardening of the ground makes it almost impossible for rainwater to replenis...

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 has been destroyed, the area of ​​wetlands has decreased, rivers have hardened, etc., resulting in changes in water ecology, and 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

For example, Chinese invention patent CN101190833A discloses a kind of permeable concrete and its production method. In this method, cement is used as the cementitious material, and natural stones or slag waste are used as aggregates. The production cost is high, and the protection of the ecological environment is limited
