Concrete wall based on solid waste residues in iron and steel industry and preparation method of concrete wall

Abstract

The invention discloses a concrete wall based on solid waste residues in iron and steel industry and a preparation method of the concrete wall. The concrete wall comprises a bearing layer and a heat preservation layer, and the bearing layer is prepared from, by mass, cement, fly ash, a thickening agent, expanded slag, a water reducing agent, water and reinforced fiber. The heat preservation layer is prepared from the following raw materials in parts by mass: cement, fly ash, a thickening agent, expanded slag, a water reducing agent, water, an expanding agent, reinforced fibers and slag wool. In the application process, under the condition that the expanded slag replaces aggregate in traditional concrete raw materials and mineral wool is added into the heat preservation layer, the expanded slag is made of blast furnace slag, and the mineral wool is made of blast furnace slag, so that indirect treatment and utilization of the blast furnace slag in the solid waste residues in the steel industry are achieved, in the application process, the requirements of wall heat preservation, water seepage prevention and sound insulation in building construction can be met, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of iron and steel industry solid waste utilization, in particular to a concrete wall based on the iron and steel industry solid waste and a preparation method thereof. Background technique [0002] Iron and steel industry solid waste refers to the solid waste generated in the process of iron and steel smelting, including blast furnace slag. Although the products of the existing blast furnace slag can be used in the construction field, combined with the development of modern construction technology, especially It is the field of templated building concrete prefabricated walls, and there is no good way to use it. [0003] Furthermore, modern architectural concrete prefabricated walls need to be covered with thermal insulation and anti-seepage materials on the outer surface after construction. This way of covering thermal insulation and sound insulation materials twice will increase the construction difficulty ...

[0002] Iron and steel industry solid waste refers to the solid waste generated in the process of iron and steel smelting, including blast furnace slag. Although the products of the existing blast furnace slag can be used in the construction field, combined with the development of modern construction technology, especially It is the field of templated building concrete prefabricated walls, and there is no good way to use it

[0003] Furthermore, modern architectural concrete prefabricated walls need to be covered with thermal insulation and anti-seepage materials on the outer surface after construction. This way of covering thermal insulation and sound insulation materials twice will increase the construction difficulty of the building construction. The thermal insulation and anti-seepage materials on the wall surface also have the risk of falling off; along with the falling off, repairs are required, which increases the cost of maintenance and repairs
