Concrete is one of the most useful materials used in construction industry ascribable to good advantages of strength to cost ratio by comparing of other construction materials such as steel, composites and wood products. A durable concrete need to be both strong and ductile performance but due to disadvantages of brittle behavior and low tensile strength in structural application, fibers have been turned into considerable solution to strengthen the concrete matrix. As the times change, advanced technologies are improving rapidly and also many types of fibers are emerged into commercial market [1]. Attribute to the superior performance on the interruption of micro crack propagation and the improvement of mechanical, durability and serviceability properties, hooked-end (5D) steel fibers play as a refinement-materials in strengthening of concrete [2]. Recycling of construction waste prevails nowadays in economic and preservation of environment from sustainability point of view [3]. Demolition of existing buildings produce brick and concrete waste to be treated for structural and non-structural applications before disposal. The proper size of aggregates is extracted by crushing in jaw machine and sieved by mechanical sieves [4].
