Abstract

This paper evaluates the impacts of the addition of STEEL FIBERs with two different percentage by weight, on flow ability parameters and HARDENED PROPERTIES of self-compacted lightweight concrete containing lightweight aggregate of SCORIA. For this purpose, was used from the STEEL FIBERs with a length of 50mm the amount 20& 40 kg/m3.With a good mix design, fresh and HARDENED PROPERTIES of each plans was evaluated. FRESH PROPERTIES such as slump flow, V-funnel, and L-box and physical properties such as, density measurements, compressive strength, splitting tensile strength, flexural strength, ultrasonic pulse velocity (UPV), flexural toughness, and dry unit weight were determined in hardened conditions. The samples were stored in water until the age 7, 14, 28, 42 and 90 days.From the result, it is clear that fibers decrease flow ability of fresh concrete, however mixes were in the acceptable range of EFNARC. The results of hardened concrete indicate, all mixes are in the range of structural lightweight concrete too. Moreover, the addition of fibers significantly increases tensile strength, flexural strength and flexural toughness.
