How to use Incineration slag

Incineration slag refers to the solid waste generated in the process of urban Incineration, usually a mixture of ash and dregs. In the process of Incineration, most organic substances are burned, but the slag still contains a certain amount of heavy metals and harmful substances. If left untreated, these harmful substances can cause pollution to the environment.

Then, how to use Incineration slag? This article will introduce several common ways of utilization.

1. Production of building materials

Incineration slag can be used to make building materials, such as bricks, concrete and pavement materials. The treated slag can replace a portion of cement, thereby reducing the use of cement and reducing the cost of building materials. In addition, slag can also improve the strength and durability of building materials.

2、 Used for landfill cover layer

Incineration slag can be used to make landfill overburden. The landfill cover layer is a material used to cover the surface of a landfill, which can reduce the odor of the landfill and prevent garbage leakage. Slag can replace a portion of soil, thereby reducing soil usage and improving the strength and durability of landfill cover.

3、 Used for road construction

Incineration slag can be used as subgrade and pavement materials in road construction. Slag can replace a portion of crushed stone and sand, thereby reducing the use of these natural resources and improving the strength and durability of roads. In addition, slag can also reduce the cost of road construction.

IV. Used in cement manufacturing

Incineration slag can be used for clinker batching in cement manufacturing. The slag contains a certain amount of components such as silica, alumina, and iron oxide, which can replace some of the raw materials, thereby reducing the use of raw materials and improving the strength and durability of cement.

The above are several common utilization methods of Incineration slag. It should be noted that in the process of using Incineration slag, the slag needs to be treated and screened to remove harmful substances and impurities. At the same time, the use of Incineration slag also needs to comply with relevant environmental regulations and standards to ensure that the impact on the environment is minimized.

In short, Incineration slag is a valuable resource, its utilization can reduce the waste of resources, reduce environmental pollution, and also can bring economic benefits to society.
