This artificial stone was formed after hardening the ash concrete mixture with a strength of 6 to 9 MPa. Lean concrete is the mixture of aggregate, ash-slag, binder and water and other additives in optimum proportions where it is appropriate to be used .
The lean ash-slag concrete foundation is one or more layers of thick slurry of ash-slag concrete which forms the load bearing part of the pavement structure after hardening. The main raw material of lean concrete is the ash-slag mixture from the CHP plant, which is stored on a dry super-level landfill. It is characterized by its own solidifying potential and binding properties.
Properties of ash-slag mixtures depend on their pozzolanic properties - there are reactions between silicate minerals (pozzolans) and calcium compounds when mixture with the binder water is thickening.
Ashes and slags are alkaline materials associated with the content of lime compounds. In this respect they are similar to traditional binders, ie. cement and lime, so the environmental impact and health and safety considerations are the same as when using traditional building binders.
