Problems solved by technology

However, there are still several problems in the development and application of ceramsite that need to be resolved urgently: First, the production process is still dominated by the traditional sintering method, which produces a large amount of carbon emissions
Second, clay ceramsite and shale ceramsite are still the dominant products, which consume a lot of land resources and mineral resources

Abstract

The invention discloses a light furnace slag particle cladded non-fired ceramsite and a preparation method thereof. The light furnace slag particle cladded non-fired ceramsite comprises a light furnace slag particle ceramsite kernel (1), a cladding power layer (2) cladding the periphery of the ceramsite kernel (1) and a reinforced and anti-carbonization fabric layer (3) cladding the periphery of the cladding power layer (2), wherein the light furnace slag particle ceramsite kernel (1) is a light furnace slag particle with the particle size of 3-15 mm. Industrial solid waste such as coal fired furnace slag, pulverized fuel ash and blast furnace slag is fully utilized as main raw materials and is turned into wealth, a non-fired sintering process replaces an original sintering process to produce the ceramsite, land and mine resources can be saved, the industrial waste is comprehensively utilized, carbon emission is reduced, and the light furnace slag particle cladded non-fired ceramsite has the important significance. The prepared light furnace slag particle cladded non-fired ceramsite is light in volume weight, high in strength, good in heat preservation and sound insulation performance, good in anti-seismic property, low in cost and good in practicability.

Description

technical field [0001] The invention relates to a building material, in particular to a slag light particle shell-coated non-fired ceramsite with light weight, heat preservation and sound insulation, safety, reliability, low cost, easy construction and wide application range and a preparation method thereof. Background technique [0002] With the development of the construction industry, the demand for the main building materials: concrete and concrete products is increasing. Ordinary concrete and products use sand and gravel as aggregates, so a large amount of sand and gravel is mined, causing environmental problems. At the same time, the height of modern buildings is getting higher and higher, the space span is getting larger and larger, and the requirements for durability are becoming more and more stringent. Therefore, in addition to large-scale mining, waste of land resources, and ecological damage to traditional sand and gravel aggregates, their own application defects...
