Mechanical properties of concrete mixed with reused ceramic tiles reinforced with steel fiber from milling processed

Abstract

This research, study the mechanical properties of concrete mixed with reused ceramic tiles reinforced with steel fiber from milling processed. The compressive strength of all concretes were designed at 300 ksc at 28 days, and control slump in the range of 10 ? 2.5 cm. The steel fiber from milling processed was reinforced at 0.50, 1.00 and 1.50 by the weight of cement content. The compressive strength, Flexural, and tensile splitting for all concrete samples were tested compare with control concrete which it as concrete mixed with reused ceramic tiles not reinforced with steel fiber. The results shown that, the reinforcing with steel fiber from milling process at 0.5 and 1.0% was affect to the higher compressive strength than control concrete of 2 and 7%, but increasing steel fiber at 1.5% was affect to lower compressive strength than control concrete of 6%. Concrete mixed with steel fiber from milling processed at 1.0% have higher splitting tensile strength than control concrete of 16%, while concrete mixed with steel fiber at 0.5 and 1.5% have splitting tensile strength equal with control concrete. The flexural strength of these concretes have higher more than control concrete about 9, 17 and 11% for reinforcing with steel fiber at 0.50, 1.00 and 1.50, respectively. In addition, the water permeability of concretes were increased when the steel fiber were reinforced increases too.
