USE OF FLY ASH FOR PRODUCTION OF CONCRETE AS AN ELEMENT
OF SUSTAINABLE CONSTRUCTION

In the article the results of laboratory research on influence of addition of mineral siliceous fly ash on concrete’s properties were presented. Fly ash has been used as a substitute of cement binder in concrete compounds because of it’s Pozzolanic properties. For research 5 cement compounds were designed: in one control concrete without the addition of fly ash, in the rest the k factor (fly ash/cement) stood at: 0,05; 0,11; 0,18; 0,25. As a cement binder, Portland cement CEM I 42,5 R was used. The results of the laboratory tests have shown the usefulness of fly ash as a substitute for cement in concrete mixes.
