Anti-bioerosion wear-resistant recycled aggregate pervious concrete and preparation method thereof

Abstract

The invention provides anti-bioerosion wear-resistant recycled aggregate pervious concrete and a preparation method thereof, and the pervious concrete comprises the following components in parts by weight: 1350 parts of recycled aggregate, 285-360 parts of cement, 25-45 parts of superfine slag powder, 25-45 parts of copper tailing slag, 90-125 parts of water, 0.16-0.22 part of a water reducing agent, 12-25 parts of redispersible latex powder, 0.15-0.25 part of cellulose ether, 0.5-4 parts of magnesium fluosilicate, 1-5 parts of sodium silicate and 0.5-3 parts of copper sulfate. Compared with common pervious concrete, the concrete has more excellent wear resistance by adding the copper tailing slag and utilizing the wear resistance of the slag, and in a humid environment, growth of moss in an outdoor semi-shady humid environment can be effectively inhibited by virtue of a copper ion slow release effect of copper sulfate in cement slurry with strong alkalinity and a compact structure; and the concrete has a certain sterilizing effect, can reduce underground water pollution, is good in working performance, low in cost and environment-friendly, saves resources, and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of urban road construction, in particular to an anti-biological erosion wear-resistant recycled aggregate permeable concrete and a preparation method thereof. Background technique [0002] The total amount of construction waste generated by the development of the construction and transportation industries in my country is huge every year, and most of them are stacked in the open air or landfilled. The utilization rate is extremely low, causing a serious waste of resources. The production and utilization of recycled aggregate from construction waste is of great significance for saving resources, protecting the environment and realizing the sustainable development of the construction industry. [0003] In recent years, urban waterlogging and heat island effect have seriously affected people's transportation. In order to promote the process of the sponge city, large areas of permeable concrete are laid in park...

Problems solved by technology

[0005] In view of this, the present invention aims to propose an anti-biological erosion and wear-resistant recycled aggregate permeable concrete, which uses copper slag as the main raw material, can turn solid waste into resources, and make full use of its wear-resistant properties to produce wear-resistant permeable concrete. In addition, adding an appropriate amount of copper sulfate, under the premise of no harm to the environment, using its slow-release effect of copper ions in concrete, can not only sterilize to reduce water pollution, but also effectively inhibit the growth of moss vegetation, which can effectively solve the problem of existing bone regeneration. The permeable concrete is not resistant to biological erosion and poor wear resistance
