Abstract

The invention relates to a crack-resistant construction waste recycled concrete wallboard, which includes a wallboard assembly, the wallboard assembly includes a wallboard body, the wallboard body includes a fireproof layer and a concrete layer, and the concrete layer consists of the following parts Made of raw materials: 22-34 parts of recycled coarse aggregate, 33-43 parts of recycled fine aggregate, 46-72 parts of crack-resistant cement, 1-13 parts of steel fiber, 1-3 parts of water reducing agent, 1 part of reinforcing agent ~4 parts, mineral powder 5~9 parts, nano silicon dioxide 5~8 parts, water 120~230 parts. The invention can greatly increase the crack resistance of the concrete layer; improve the fluidity of the concrete mixture and have strong economic benefits; can improve the durability and wear resistance of the concrete surface; and can realize the installation limit of the wallboard function, easy to install.

Description

technical field [0001] The invention relates to the technical field of concrete wallboards, in particular to a crack-resistant construction waste recycled concrete wallboard. Background technique [0002] With the continuous advancement of urbanization, most of the old buildings in urban areas are being demolished and rebuilt. During the construction process, a large amount of construction waste is inevitably generated, and valuable construction waste is widely used and can be separated into single The components can be used or mixed; among them, waste construction waste can be used for recycled concrete, and recycled concrete refers to the waste concrete blocks that are crushed, cleaned and graded, mixed with grading in a certain proportion, and partially or completely replaced by sand Natural aggregates such as stones (mainly coarse aggregates), and then cement, water, etc. are added to the new concrete. [0003] In the prior art, since most of the surface of recycled agg...
