Abstract

The invention discloses ceramsite recycled concrete, a hollow block masonry and a preparation method of the hollow block masonry. The ceramsite recycled concrete consists of the following raw materials in parts by weight: 360-440 parts of ceramsite, 660-860 parts of a recycled fine aggregate, 400-520 parts of cement and 150-200 parts of water. The ceramsite recycled concrete disclosed by the invention adopts the ceramsite as a light-weight coarse aggregate, adopts waste concrete as the recycled fine aggregate, integrates the characteristics of a lightweight aggregate and recycled aggregate concrete, and ensures that the ceramsite recycled concrete has the advantages of energy conservation, waste utilization, environmental protection, light weight, heat preservation, heat insulation and the like. A hollow block manufactured by adopting the ceramsite recycled concrete disclosed by the invention is a green wall material which has the performances of light weight, environmental protection, heat preservation and heat insulation, and has good physical, mechanical and thermotechnical performances.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a ceramsite recycled concrete and hollow block masonry and a preparation method. Background technique [0002] With the rapid development of my country's construction industry, the problem of resource shortage is becoming more and more serious. High-quality natural aggregates have been exhausted in some areas. Large-scale quarrying and large-scale discarding of construction waste have seriously damaged the natural landscape and ecological environment. , deviated from the sustainable development strategy of my country's economy and environment. Therefore, from the perspective of recycling construction waste, saving natural resources and promoting ecological environment coordination, it will be of great practical significance to study and utilize waste concrete. Aggregate made of waste concrete after cleaning, crushing, grading and mixing in a certain proportion is calle...
