Laboratory analysis of slag

You wish to have your slag analyzed by a laboratory?

What is clinker?

Bottom ash is a solid residue resulting from the combustion of materials and is composed of incombustible materials (e.g.: glass, metals, silica, alumina, limestone, lime and unburned materials…).

There are two types of bottom ash:

  • the first is the residue of the incineration of coal, or coke, in industrial furnaces
  • the second one comes from the incineration of household waste in non-hazardous waste incineration units (UIDND)

Bottom ash has certain advantages, notably its abundance and its excellent geotechnical characteristics. These characteristics make it a material that can be used for many construction applications.

Thus, it can be found in the form of solid breeze blocks of any size, load-bearing walls made of clinker concrete but also in road construction.

Why is it necessary to analyze the slag?

The bottom ash resulting from waste treatment is more or less polluted and must be recycled with care. By its very nature, bottom ash can contain high levels of dioxins and many pollutants such as heavy metals and hydrocarbons. 

In order to protect the environment and to avoid any risk, the legislation requires leaching tests on many substances. Thus, the following elements As, Ba, Cd, Cr Total, Cu, Hg, Mo, Ni, Pb, Sb, Se, Zn, Fluorides, Chlorides, Sulfates must be analyzed. It also specifies the conditions of use out of the floodable zones, near the water courses and the points of catchments of drinking water…
