Popis:	This chapter treats composition and properties of the burnt rocks of mine dumps and ash-slag waste. Beginning with formation sampling, physical and chemical properties and granulometric and mineralogical compositions of samples from different Russian mines are studied by physico-mechanical methods. Then hydraulic activity of ash and burnt rocks of mine dumps, allowing one to use these wastes as active mineral additives, is studied. Kinetics of the involvement of additives in the reaction with calcium hydroxide are discussed. Changes in the specific surface of the additive composition and in the adsorption activity of a mixture of fly ash and burnt rocks are considered.
