Application of brick-concrete recycled fine aggregate in lightweight aggregate concrete and mixing method

Abstract

The invention provides application of brick-concrete recycled fine aggregate in lightweight aggregate concrete, and belongs to the field of civil engineering materials.The application of the brick-concrete recycled fine aggregate in the lightweight aggregate concrete comprises a mixing station, and the mixing station is composed of a vibration soil removal feeding machine, a jaw crusher, an impact crusher, an iron remover, a cone crusher and vibrating screen equipment; the method comprises the following steps: selecting brick-concrete waste for pretreatment, manually screening out reinforcing steel bars and wood, feeding into a mixing station to produce brick-concrete recycled fine aggregate, conveying the brick-concrete recycled fine aggregate to a stock bin for storage by a conveying belt, and producing and processing the lightweight aggregate concrete with the grade of LC10 or below. The lightweight aggregate concrete is prepared by strengthening and adjusting the brick-concrete recycled aggregate and matching with a specific external agent, so that the functionality of the lightweight aggregate concrete is improved, and the application range is wide; building solid waste is treated, waste is turned into wealth, secondary value is created, and the environment-friendly and energy-saving effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering materials, and in particular relates to the application and mixing method of brick-mixed recycled fine aggregate in lightweight aggregate concrete. Background technique [0002] With the orderly development of large-scale urbanization, many buildings that have reached the service life or obeyed the demolition design and planning have been renovated or demolished, resulting in more and more construction solid waste. If many construction solid wastes are used for landfill treatment, it will cause a lot of waste of space resources and waste of human, material and financial resources, which is not in line with the concept of sustainable development. [0003] With the country's increasing requirements for building energy conservation and building functionality, the research and application of high-performance lightweight aggregate concrete is also in urgent need of development.

Problems solved by technology

[0008] The present invention aims to solve the problem of brick-concrete building solid waste treatment. Through the refined treatment process of crushing and reprocessing, the application of brick-concrete regenerated fine aggregate in light-weight aggregate concrete with a label below LC10 is fully referenced. Under the premise of technical data, provide a kind of application and mixing method of brick-concrete recycled fine aggregate in light-weight aggregate concrete, and make full use of the fine-grained recycled fine aggregate for brick-concrete recycled fine aggregate below LC10. Concrete is used for construction; wherein the present invention provides the application of brick-mixed recycled fine aggregate in lightweight aggregate concrete, including a mixing station, wherein the mixing station is composed of a vibrating soil removal feeder, a jaw crusher, an impact crusher, Composed of iron remover, cone crusher and vibrating screen equipment, select brick-concrete waste for pretreatment, manually sieve to remove steel bars and wood, send it to the mixing station to produce brick-concrete recycled fine aggregate, and brick-concrete recycled fine aggregate is conveyed by the conveyor belt Transport to the silo for storage, and produce and process a kind of lightweight aggregate concrete with a label below LC10
