ABSTRACT
In most civil constrictions, concrete members need to gain some ductility to resist the dynamic loads which it suffered. For sustainability and economical reasons, scrapped tires rubbers are the most cheap material able to achieves this goal. The bad manner in such replacement is that, the high replacing percentages cause a large drop in concrete mechanical properties till becomes unstructural. This paper offers six structural rubcrete mixes and discuss its properties after replacement. Slump, density, water absorption, compressive strength for cubes and cylinders, impact resistance, flexural strength, splitting, ultrasonic and stress versus strain curves were tested and discussed. It can be concluded that, the sustainable rubcrete mixes still structural in spite of the dropping in strength due to the replacing process. Concrete tensile, compressive and flexural strength minimized for every incrementing in rubber amounts due to the loss of bond between mortar and the rubbers.
