Abstract

The effect of recycled materials as a recycled aggregate (crushed red brick and crushed ceramic)
on the fresh and hardened properties of Recycled Self-Compacting Concrete (RSCC) was
investigated. Recycled materials were used to replace coarse aggregate at different ratios of 25%,
50%, 75% and 100% to produce RSCC mixes. Twenty one concrete mixes were cast and test to
fulfill the aim of this paper. This paper aimed at studying the properties of RSCC mixes and
evaluating the behavior of RSCC beams under flexural loads. Nine tested loading simply
supported concrete beams were tested in flexure. The fresh properties of RSCC were evaluated
using slump flow, J-ring and V-funnel tests. Compressive strength, splitting tensile strength and
flexural strength were performed in order to investigate mechanical properties. The density for
different mixes was evaluated. The behavior of the tested beams was investigated with special
attention to the deflection under different stages of loadings, initial cracking, cracking pattern, and
ultimate load. The average of the compressive strength decreased by 34% and 26% for the mixes
with crushed red break and ceramics, respectively compared to that of control mix was observed.
In addition, the density for the mixes with crushed red brick decreased by 14 % compared to that
of control mix. The obtained results presented the properties of this concrete were expected from a
structure point of view, and that the recycled coarse aggregates can successfully be used for
making of SCC.
