Problems solved by technology

[0002] At present, the waste concrete discharged from the demolition of buildings is the largest waste in the construction industry. The discharge of waste concrete is increasing every year, causing serious environmental problems and causing secondary pollution to the environment.
However, sand and gravel aggregates, which are the most used in the production of concrete in the construction industry, have been exhausted and in short supply in a few areas. and natural landscape

Embodiment Construction

[0009] The preparation method of the novel building material of the present invention is realized in this way, and is described in detail below.

[0010] The method of producing green recycled building materials, the construction waste after the building is demolished, and the regenerated sand in the state of fine sand is mechanically crushed, and its technical index: bulk density 1180kg / m 3 , mud content 5.0%, mud block content 1.5%, water absorption (natural water content) 7%; use recycled sand to prepare concrete and mortar, add: triethanol 15%, ferric oxide 25%, fly ash 60 % composition of additives, recycled sand: additive = 95:5, so that the performance of the concrete mixture can reach: strength grade: C20, water-cement ratio: 0.60-0.62, slump cm: 5.0.

[0011] The preparation method of the new building material of the present invention uses green recycled building materials to prepare concrete and mortar in the test, and the mix ratio design is designed and prepared ac...

Abstract

The invention relates to a preparation method of a novel building material. The novel building material preparation method is characterized in comprising the following steps: (1) construction waste obtained after building demolition is mechanically crushed into reclaimed sand with a state of fine sand, wherein the technical specifications for the reclaimed sand are as the follows: a bulk density is 1180kg / m<3>, a clay content is 5.0%, a clay lump content is 1.5%, and a water absorption rate is 7%; (2) the reclaimed sand is used for preparing concrete and mortar. An additive composed of 15% of triethanolamine, 25% of ferric oxide and 60% of fly ash is added, and the ratio of the reclaimed sand to the additive is 97:3, such that the performance of an obtained concrete mixture can reach the following specifications: the strength level is C20, the water-cement ratio is 0.60-0.62, and the slump by cm is 5.0. With the novel building material preparation method, environment pollution caused by waste discharged during building demolition is effectively solved, and a problem of natural sand resource constraints is solved.

Description

technical field [0001] The invention relates to a green recycled building material produced by using waste discharged from demolished buildings, in particular to a preparation method of a new type of building material. Background technique [0002] At present, the waste concrete discharged from the demolition of buildings is the largest waste in the construction industry. The discharge of waste concrete is increasing every year, causing serious environmental problems and causing secondary pollution to the environment. However, sand and gravel aggregates, which are the most used in the production of concrete in the construction industry, have been exhausted and in short supply in a few areas. and natural landscape. Contents of the invention [0003] The present invention overcomes the above-mentioned defects, and aims to provide a method for preparing a new type of building material for solving the problem of using waste discharged from demolished buildings. [0004] Brie...
