Confining effect by hot rolled steel and cold formed steel on coconut shell concrete with quarry dust
Properties of concrete using quarry dust as fine aggregate and coconut shell as coarse aggregate were examined. Hot rolled and cold formed steel were used as an external confinement on both conventional concrete and coconut shell concrete mixes. Workability, density of concrete, compressive, flexural and impact resistance were considered and evaluated. Uses of quarry dust in place of sand reduce workability and increase density of concretes. In case of without confinement, the compressive strength variation between cubes strength and cylinders strengths are traditional and it is not if it is confined. Flexural specimen with confinement does not fail and stands enough without any sign of failure in case of hot rolled steel. However, in case of cold formed steel, flexural specimen with confinement enhances approximately nine times of the flexural specimen without confinement and stands enough with ductile manner. Hot rolled and cold formed steel confinement effect is not allowing the impact specimen to form crack and in turn not allows failing the specimen. This study proves that the use of quarry dust in place of sand augmented the mechanical properties of both coconut shells concrete and conventional concrete as well. Confinement effect improves promptly the mechanical properties of concretes.
