The Effect of Scrap Tires Recycled Steel Fibers on Some Hardened Properties of Green SCC

The purpose of this study is to investigate some hardened properties green self-compacting concrete (GSCC) with 15% volumetric replacements crushed clay brick waste as coarse aggregate and reinforced scrap tires recycled steel fibers (STRSF) 0, 0.25, 0.5and 0.75%volume fraction 40 an aspect ratio. Also, a combination two STRSF ratios 60 was used in GSCC hybrid fiber reinforcement (0.25 0.25%, 0.5 0.25 0.5% 65, respectively). Scrap had been improve the containing aggregate. Dry density, water absorption, compressive strength, splitting tensile flexural Ultrasonic Pulse Velocity (UPV) were among SCC that investigated. To achieve study, seven mixes prepared.SCC UPV are all increased increase content self-compacted concrete. Including different volume fractions tire strength between 2.54% 23%. about 5.6% 13.9%, from 1.6% 14.8%. All show good performance according classification limits high so these applicable for weather conditions construction projects.
