Copper slag concrete admixed with polypropylene fibres

Projektiranje održivog betona postao je glavni zahtjev u današnjoj industriji betona. U ovom radu je prikazan i analiziran dio opsežnog istraživačkog projekta koji je usmjeren na istraživanje mogućnosti korištenja bakrene zgure (eng. copper slag - CS) i polipropilenskih (PP) vlakana (eng. polypropylene fibre). Ispitivanja su provedena s ciljem utvrđivanja obradljivosti, gustoće, tlačne čvrstoće, vlačne čvrstoće i svojstava mikrostrukture betona te granične nosivosti armiranobetonskih greda izrađenih od takvog betona.A sustainable concrete design has become an imperative requirement for the present-day concrete industry. A part of an extensive research project aimed at studying possibilities for using copper slag (CS) and polypropylene (PP) fibres in concrete is presented and analysed. Measurements were conducted to investigate the workability, density, compressive strength, tensile strength, and micro-structural properties of concrete, as well as the ultimate load carrying capacity of reinforced-concrete beams made of this type of concrete
