The property that influences the binding properties of slag is its hydraulicity. The term ?hydraulicity? is now used internationally to describe cements and other binders that set and harden as a result of chemical reactions with water and continue to harden even if subsequently placed under water. There are a few exceptions but these chemical reactions generally involve calcium, silica, and aluminum constituents that react with water to form a whole family of calcium silicate and calcium aluminate hydrates. The chemical composition in itself is only a limited guide to the hydraulic properties; the key is in the way the components are combined into the various silicates and aluminates. Next factors influencing the hydraulicity are the phase composition, granulometry and the cooling rate. Hydraulicity is the property that is typical for materials used in civil engineering and because the building industry uses a lot of waste materials from metallurgy first of all slags, it was very important to know the hydraulicity of metallurgical slags. The main goal of the realized experiments was to determine the influence of chemical composition and on compressive strength of metallurgical slags.
