Problems solved by technology

In 2007, the production of steel slag in my country has reached 65.46 million tons, and it is still increasing every year, while the utilization rate is only 10%. Most of the steel slag is still discarded, which not only occupies farmland, but also pollutes the environment
[0004] At present, the main reason for the low utilization rate of steel slag is that the stability of steel slag is not good, which affects its normal use in engineering construction.

Abstract

The invention provides a smelting waste slag light composite artificial stone which comprises a main body material prepared from structural slurry. The structural slurry comprises a base material, a cementing agent, water, a polymeric additive, an alkaline excitant and a foamer aqueous solution or a foam material. A production method of the smelting waste slag light composite artificial stone comprises the following steps: by pre-treating the smelting waste slag which is used as part of cementing agent and base material, introducing the foamer aqueous solution or the foam material; stirring the components; and casting and carrying out vibration molding in a die. The stone provided by the invention is scientific in formula and reasonable in process and has ecological environmental protection property, high mechanical strength, low cost and excellent operating performance. The self weight of the smelting waste slag light composite artificial stone is reduced, and the heat preserving and insulating properties and the soundproof, fireproof and saltpetering-preventing properties of the smelting waste slag light composite artificial stone are improved. The stone has extremely strong durability and color stability in various severe conditions.

Description

technical field [0001] The invention relates to a lightweight composite artificial stone made of smelting waste residue and a production method thereof. Background technique [0002] Smelting waste light-weight composite artificial stone is manufactured through material pretreatment, adding functional additives, and adopting special technology. Artificial stone with thermal properties. [0003] Among the smelting waste slag, steel smelting slag has the largest proportion. Steel slag is a by-product produced in the steelmaking process, about 0.1-0.14 tons of steel slag is produced per 1 ton of steel. In 2007, the production of steel slag in my country has reached 65.46 million tons, and it is still increasing every year, while the utilization rate is only 10%. Most of the steel slag is still discarded, which not only occupies farmland, but also pollutes the environment. The main way out for large-scale resource utilization of steel slag is as cement raw material and concre...
