Novel preparation method of red mud light-weight wall material

Abstract

The invention discloses a novel preparation method of red mud light-weight wall material, comprising the steps of mixing and grinding 1-10 wt% of waste glass powder, 1-10 wt% of rock wool waste, 1-10 wt% of fly ash, 1-20 wt% of gangue, 1-10 wt% of polished tile waste, 1-10 wt% of waste ceramic tile powder, 94-30 wt% of red mud and 5-10 wt% of additional pulverized coal, and then obtaining uniformmixed powder; baking the mixed powder for 1-4h at 600-1200 degrees centigrade; and cutting to obtain the red mud light-weight wall material. The aperture size of the prepared light-weight wall material is 0.1-3mm; the inner holes and outer holes are distributed uniformly and are closed holes; the heat preservation and shock resistance is far higher than those of aerated concrete block; used raw materials are all industrial wastes, so that the production cost is low and the environment pollution is reduced; and the prepared light-weight wall material has characteristics such as light weight, porous performance, heat insulation, no toxicity, no microbes, tasteless performance and so on, and is convenient to construct and is economic and environment-friendly. Most importantly, the effective solution to the world problem of pollution of industrial waste red mud is found.

Description

technical field [0001] The invention relates to a novel preparation method of red mud lightweight wall material, which belongs to the technical field of porous ceramic preparation technology. Background technique [0002] At present, clay bricks, clay hollow bricks, cement mortar lattice bricks, aerated concrete blocks, etc. are mainly used as wall materials. Due to the high weight, high water absorption rate and high thermal conductivity of the above materials, the building has heavy load bearing, poor thermal insulation performance and earthquake resistance. The performance is poor, and it consumes a large amount of natural resources such as clay, which does not meet the performance requirements of modern building materials for shock resistance, heat preservation, and energy saving. Contents of the invention [0003] The purpose of this invention is to provide a kind of novel preparation method that can overcome above-mentioned defective, low-cost lightweight wall materi...
