Abstract

This paper intends to study the possibility of producing fiber recycled self-compacting concrete (FRSCC) using demolitions concrete as a coarse aggregate. Polypropylene fibers (P.P.F) were used in recycled self-compacting concrete (RSCC) with different percentages of coarse recycled concrete aggregate. Nine concrete mixtures were set up to accomplish the objective proposed at this paper. Polypropylene fibers fraction changed from 0% to 0.15% by the volume of concrete and the ratio replacement of recycled coarse aggregate with natural aggregate was 25%, 50%, 75%, and 100%. The fresh properties of (FRSCC) and (RSCC) were assessed utilizing V-funnel, L-box and slump flow tests. Flexural strength, compression strength, and tensile strength tests were performed with a specific end goal to examine mechanical properties. The results indicate that the optimum volume fraction of polypropylene fibers was (0.1%) for the mixes contained recycled coarse aggregate (75%), for optimum content of (P.P.F), the compression strength, flexural strength, and splitting tensile strength; improved by (34%), (14%), and (8.1%), respectively with consideration to control mix. Also the flexural strength and the tensile strength for the mixes were improved with increasing the fibers ratio compared with control mix
