Behaviour of self compacting concrete columns with recycled brick aggregates

Abstract

— Recycled brick aggregates are preferable alternatives to natural aggregates for minimizing exploitation of natural resources. In this investigation, experimental and analytical works are performed to investigate the behaviour of SCC columns constructed using partial replacement of natural aggregates by RBA and reinforced with steel fibres. The parameters considered for this study is proportion of RBA in SCC mixture and the amount of fibres used. The results of this study reveal that the use of RBA in the place of natural aggregates slightly reduces the strength properties, but this reduction compensated by adding mineral admixtures and steel fibres. The analytical results agreed with the experimental results for SCC columns behaviour.
