ABSTRACT
Recycling of the binder and fine aggregate is possible after the thermal treatment of fine fraction, produced during the manufacture of coarse aggregates, from waste concrete. Recovered material is sintered in furnace at temperatures of about 700oC and then ground in a ball mill to a fineness of cement. Depending on the type of initial waste concrete a binder with the compressive strength of the paste from 10 MPa to 30 MPa, can be obtained. The paper presents the results of such binders production, from different class waste concrete.
