Stabiliser

Stabiliser is the mixture of fly ash and a binder produced in the mixing facility of a power station or being the final product of the fluid way of incinerating coal, with the fly ash – produced by technological adjustment of fuel – already containing lime.

Stabiliser is supplied in moist or dry condition, ready to be applied immediately. Cement itself or cement clinker may be used as another binder put into stabiliser.

Where does the stabiliser certified and supplied by our company come from?

Our principal supplier of mixed stabiliser is the company ČEZ Energetické produkty s.r.o., namely from the power stations Mělník, Chvaletice and Počerady. We supply the „ready-made“ stabiliser from fluid incineration, produced at the power plant Tisová.

What quantities of stabiliser are we able to supply?

We are currently able to supply mixed stabiliser from the power station Počerady, Mělník and Chvaletice. We supply stabiliser generated by fluid incineration of coal from the power station Tisová. As the material is not produced on a standard basis in the power station’s facility, the options of stabiliser suppliers shall therefore be always specified in advance.

While moistening stabiliser, the material reacts with water, starting up inner hydratation processes within several minutes. The chemical process generates pozzolanic reactions similar to the cement-hardening process, creating a similar binding ability. Once hardened up, the stabiliser properties are comparable to the properties of so-called poor concrete. If using higher quantities of lime (more than 3%), the material may be considered to be impermeable (resistant to frost and water), with firmness in a pressure 5-10 MPa.

Due to its above-mentioned properties, stabiliser has a great range of utilisation predominantly at geotechnical activities.
