Problems solved by technology
Through years of research and development, a series of building material products have come out, but these used solid wastes are estimated to only account for 30-50% of the total waste, and the remaining waste has brought great harm to the environment and society. harm, and at the same time, some useful resources in these wastes cannot be rationally utilized, resulting in a great waste of resources

Embodiment Construction
[0034] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0035] In order to fully illustrate a kind of muck concrete and its preparation method, the required muck curing agent is made according to figure 1 Produced by the method shown.
[0036] from figure 1 It can be seen that the slag soil curing agent is processed by a mill into fine powder and solid waste such as fly ash, desulfurization ash or waste gypsum powder, or ceramic ash. After fully mixing and stirring, add an active stimulating admixture to mix production;
[0037] The production process of ballast concrete is as follows: figure 2 As shown, it is made by adding muck solidifying agent to muck and silt, adding water, stirring and mixing, forming and curing. According to the required strength of muck concrete, it is necessary to prope...

Abstract
The invention discloses a slag concrete and a preparation method thereof. The aggregate of the slag concrete is composed of slag, silt, steel slag, gravels and sand; the binding materials of the slagconcrete are slag curing agent processed from multiple industrially discharged solid wastes by mixing exciting additives into the solid wastes such as superfine slag powder, coal ash, desulfurized ash, waste gypsum, ceramic ash or cement; the uniaxial compressive strength of the slag concrete is 0.5-30 MPa. The slag concrete can be common slag concrete, heavy state slag concrete and fiber slag concrete. Application of a variety of the slag concrete fills in the gap of large amount of application of low-strength concrete materials in construction foundation treatment, slope strengthen, rive andsea bank protection and temporary facility construction, and achieves the social values of energy saving, emission reduction, green and environmental protection and economic benefits of reducing building costs.
Description
technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for processing construction dregs and utilizing industrial solid waste. Background technique [0002] In the field of civil engineering, concrete materials have reached a large number and wide application. As we all know, concrete materials are building materials formed by mixing cement, coarse aggregate (stone), fine aggregate (sand), water and admixtures. The uniaxial compressive strength grade distribution of concrete materials is C10~C100. For concrete materials, the aggregate requirements are relatively strict, such as strict control of mud content and particle size distribution, or gradation requirements. For low-strength concrete, the requirements for its aggregate are relatively loose, but according to the current specifications, even if the preparation of low-strength concrete is made, the gradation of the aggregate and its mud content still have some...
