Method for preparing MU5 regenerated solid brick by building waste

Abstract

The invention discloses a formulation and a preparation technology of an MU5 solid brick prepared from building waste; the MU5 solid brick comprises the components of powder which is formed by crushing and screening construction waste crushed bricks and has the particle size of less than 4.75mm, natural sand with the particle size of less than 4.75mm, 32.5R ordinary portland cement, lime powder and tap water. The composition of the MU5 solid brick only contains fine aggregate, and lime powder is adopted as an additive, so that the weight of the single regenerated brick is greatly lightened, and the regenerated brick prepared by using the method disclosed by the invention not only has the strength grade reaching the requirement, but also has the advantage of being light in weight. Furthermore, the formulation and the preparation technology of the MU5 solid brick prepared from the building waste have very high economic benefits, social benefits and ecological benefits, thus being capable of being used for environmental engineering, a resources engineering and an energy engineering which benefits to the nation and people.

Description

technical field [0001] The invention relates to a method for preparing MU5 regenerated solid bricks by using construction waste. Background technique [0002] With the development of my country's urbanization and the advancement of industrialization, a large amount of construction waste and industrial waste residues have been produced. The disposal of these construction wastes requires a large amount of land to be piled up and landfilled, which will not only cause waste of land resources, but also accompany with All kinds of environmental pollution and social public hazards. At the same time, our country is also facing a series of problems such as the rapid growth of the demand for construction resources and the increasing shortage of construction materials. [0003] At present, more than 70% of the building materials in civil buildings in my country are used for walls, and most of the wall materials are ordinary fired clay bricks; preparing these clay bricks consumes a lot ...
