Beam-column joints made of self-compacting concrete containing recycled coarse aggregates and nano-silica
This research focuses on the analysis of beam-column joints prepared using self-compacting concrete (SCC) incorporated with nano-silica (NS) and recycled coarse aggregates (RCA). For this purpose, beam-column joint behaviour of normal concrete, SCC incorporating RCA and NS was examined under static loading condition. Analysis of the experimental results indicates that the performance of the joints made with RCA is comparable with that of normal concrete in terms of cracking and ultimate load-carrying capacity. This study also depicts that compressive strength (CS) of SCC made with 100% RCA is somewhat higher than that of SCC made with normal aggregates. Moreover, enhancement in CS can be obtained with the introduction of NS in SCC containing 100% RCA.
