Abstract: This paper investigates the effect of polypropylene fibers on slump flow of self-compacting lightweight concrete. The water/binder ratio that was used in concrete mixes was set to 0.4. four mixes with different proportions of Polypropylene fibers were prepared and adjusted by inserting micro-silica and fly ash as supplementary cementitious materials. The percentages of micro-silica and fly ash were fixed to have the values of 5% and 20%, respectively. The replacement ratios of Polypropylene Fibers were from 0% up to 0.4%. The graduation, specific gravity, water absorption, and fineness modulus have been testified for two types of local fine aggregates, in addition to, the graduation, specific gravity, water absorption, particle shape, and surface texture of lightweight scoria coarse aggregate. the relationships between the proportions of fibers and slump flow of fresh concrete have been identified as well.
