Effect of recycled aggregate on behaviour of tied reinforced fibrous rectangular short columns
This study focuses on studying the behaviour of fibrous rectangular short columns (tied reinforced) using recycled coarse aggregate (f’c, ft, Ec, fr) is found by using recycled aggregates with comparison to normal aggregates with and without using steel fibres. For this purpose, five (5) tied short...

| description | This study focuses on studying the behaviour of fibrous rectangular short columns (tied reinforced) using recycled coarse aggregate (f’c, ft, Ec, fr) is found by using recycled aggregates with comparison to normal aggregates with and without using steel fibres. For this purpose, five (5) tied short columns were cast (150 mm length x 150 mm width x 600mm height) with different percentage of recycled coarse aggregate (0%, 50%, 100%) and different percentage of steel fibre (0%, 0.5% and 1%). The study resulted that when adding the 50% normal aggregates with 50% recycled aggregates, a decrease of (10%, 18%, 30% and 22%) (compressive strength, splitting tensile strength, flexural strength and elasticity module) respectively was observed, when replacing the100% normal aggregates with 100% recycled aggregates, a decrease of (30%, 35%, 58% and 63%) (Compressive strength f’c, splitting tensile strength ft, flexural strength fr and elasticity module Ec) respectively was observed. The changes in the compressive strength by adding steel fibres to the RAC by a proportion (0.5%, 1 %) resulted in a significant increase of about (14 %, 35 %), respectively. |
