Properties of concrete made from industrial wastes containing calcium carbide residue palm oil fuel ash rice husk-bark ash and recycled aggregates
Type Of : Academic Manuscript
Type : Civil Engineering
This concrete was made by using several industrial wastes in both binder and aggregates. Calcium carbide residue (CCR) mixed separately with palm oil fuel ash (PA) and rice husk-bark ash (RA), and was used as a binder instead of Portland cement in the concrete mixture. Furthermore, recycled aggregates were fully replaced natural aggregates in order to cast concrete specimens (CCR-PA and CCR-RA concretes). Concrete properties namely compressive strength, chloride migration, and water permeability of CCR-PA and CCR-RA concretes were evaluated and compared with the conventional concrete (CON concrete). The results indicated that CCR-PA and CCR-RA binders could be used as a new cementitious material in recycled aggregate concrete, even though the CCR-PA and CCR-RA binders contained no Portland cement. The characteristic compressive strength of CCR-PA and CCR-RA concretes developed similar to CON concrete. Moreover, CCR-PA and CCR-RA binders in the mixtures were effectively improving the chloride migration and water permeability of recycled aggregate concretes. These results also suggested that CCR-PA and CCR-RA concretes can be used as a new environmental friendly concrete because of these concretes can reduce as much as CO2 emissions and environmental problems.
