Abstract

The invention discloses a clay ceramsite used for highway greening. Clay, copper mine tailings, fly ash and a paper pulp waste liquid are adopted as raw material, so the cost is greatly reduced, and wastes are recycled. A preparation method of the clay ceramsite has the advantages of simplicity, easy industrialization and wide sources of the raw materials. The water absorption rate of the clay ceramsite is greater than 93%, the unit weight is greater than 590kg / m<3>, the compressive strength is greater than 30Mpa, and the granularity is 1-10[mu]m, so the clay ceramsite is very suitable for being used in highway greening.

Description

technical field [0001] The invention belongs to a clay ceramsite used for expressway greening, in particular to a clay ceramsite used for expressway greening, which uses natural clay, fly ash, tailings, minerals and waste as raw materials, and belongs to expressway greening field. Background technique [0002] As people's requirements for greening are getting higher and higher, ceramsite has gradually become the main material for covering greening. Covering with ceramsite can keep heat, save water, promote plant growth, and improve soil ecological environment, which is an economic benefit. Very tall planting method. [0003] On the expressway, due to the large amount of vehicle exhaust, heat dissipation and weather, the soil water evaporation in the green belt is very large. The central isolation zone of the Langzhuo Expressway has been covered with ceramsite to effectively increase the soil water retention. And can improve the photosynthesis and growth of plants. However...
