Abstract

The invention relates to recycled concrete produced from construction wastes and a production method thereof. The recycled concrete is prepared by mixing and stirring recycled coarse aggregates, recycled fine aggregates, binding materials and water and is C10-C20 in strength grade, wherein each cubic meter of the recycled concrete contains the following components: 650-770kg / m<3> of recycled coarse aggregates, 576-764kg / m<3> of recycled fine aggregates, 267-400kg / m<3> of binding materials and 255-345kg / m<3> of water; the recycled concrete is used for preparing wallboard components or walls having not high requirement on strength. The recycled concrete is produced from waste bricks which serve as recycled coarse aggregates and waste concrete functioning as recycled fine aggregates through reasonable proportions, so that the recycled concrete meets a requirement of constructing walls and wallboards, thus solving problems in recycling waste bricks and waste concrete in the construction wastes and solving preparation technical problems.

Description

Technical field:

[0001] The invention belongs to the technical field of building wall materials, and in particular relates to recycled concrete produced by using construction waste as a raw material for wall construction and a production method thereof. Background technique:

[0002] After investigation and research, a large number of old buildings in urban and rural areas in my country adopt masonry structures or mixed structures with traditional sintered clay bricks as the main material, resulting in the main components of construction waste generated during urban construction and old city renovation. Clay bricks, waste concrete components and test blocks. At present, the traditional treatment methods for construction waste are mainly landfill and open-air stacking, and the rate of resource reuse is very low. At the same time, on the one hand, this treatment method invades and destroys the land, aggravating the tension and waste of land resources; on the other hand, it pol...
