Abstract:
This research aimed to study concrete properties such as compressive strength, chloride migration, and water permeability of concrete made from industrial wastes. The wastes were Gground calcium carbide residue (CCR) and ground fly ash (FA) and were mixed together for use as a binder. Recycled aggregates were used in place of natural aggregates to produce concrete (CCR-FA concrete). Properties of CCR-FA concretes were evaluated and compared with the conventional concrete made from Portland cement and natural aggregates (CON concrete). The results showed that the use of CCR-FA binder in recycled aggregate concrete did not change the characteristic compressive strength of concrete. Compressive strength of CCR-FA concretes was similar to that of CON concrete. The chloride migration and water permeability of CCR-FA concretes were the same or lower than that of CON concrete. These results indicated that CCR-FA concretes could be used as a new environmental friendly concrete because these concretes can reduce environmental problems by using the industrial wastes as raw material to produce concrete.
