Method for preparing foamed concrete by using coal gangue
The invention provides a method for preparing foamed concrete by using coal gangue. The method comprises the following steps: I, crushing the coal gangue by adopting a jaw crusher, and then carrying out ball milling on the crushed coal gangue in a ball mill to obtain coal gangue powder; II, activating the coal gangue powder in a muffle furnace; III, mixing and stirring bean powder and deionized water to obtain a foaming agent; and IV, uniformly mixing the coal gangue powder, cement, sand, broken stone and a water reducing agent to obtain a mixture, then uniformly mixing the mixture and water to obtain slurry, adding the foaming agent into the slurry, uniformly mixing, pouring and forming, demolding and maintaining to obtain the foamed concrete. The coal gangue is adopted as a raw material, the coal gangue is activated and then is mixed with the foaming agent to prepare the foamed concrete, and a product has the characteristics of light weight and good sound insulation and heat insulation effect. The coal gangue is used for preparing the foamed concrete, so that not only is the additional value of the coal gangue sufficiently realized, but also the environmental pollution caused by the coal gangue can be reduced.
