Problems solved by technology

At present, my country's annual steel output exceeds 500 million tons, and the steel slag produced is nearly 100 million tons. However, the utilization rate of steel slag is less than 10%. In addition, the untreated steel slag has not only occupied a large amount of arable land, but also caused serious damage to the production and development of iron and steel enterprises. pressure
Moreover, it pollutes the environment, brings serious harm to the soil, water body, and atmosphere, and even affects people's health.

Abstract

The invention relates to powdered putty for an exterior wall prepared from ultrafine steel slag micropowder, belonging to the technical field of solid waste comprehensive utilization and chemical building materials. Ultrafine steel slag micropowder is used as a main raw material, and a certain amount of cement, desulphurization gypsum, talc powder, emulsion powder and water-retaining agent are added to prepare the powdered putty for the exterior wall after sufficiently and uniformly mixing. The powdered putty for the exterior wall takes industrial solid waste as the raw material, the production cost of the putty for the exterior wall is greatly reduced; the putty is in a powdered state, so that the putty is convenient to transport; the powdered putty for the exterior wall has a simple production process and is convenient to construct; and the powdered putty for the exterior wall has the characteristics of strong bonding force, no cracking, water resistance, alkali resistance and the like.

Description

technical field [0001] The invention relates to a dry powder exterior wall putty made of ultrafine steel slag powder, which belongs to the technical field of comprehensive utilization of solid waste and chemical building materials. Background technique [0002] Steel slag is industrial solid waste produced by steelmaking converters or electric furnaces. At present, my country's annual steel output exceeds 500 million tons, and the steel slag produced is nearly 100 million tons. However, the utilization rate of steel slag is less than 10%. In addition, the untreated steel slag has not only occupied a large amount of arable land, but also caused serious damage to the production and development of iron and steel enterprises. pressure. And pollute the environment, bring serious harm to soil, water body, atmosphere, even bring impact to people's health. In the process of resource utilization of steel slag, the use of steel slag in the construction industry from different aspects...
