A Study on Self‐Consolidate Concrete in Experimental Reinforced‐Concrete Beam Column Structures with Alccofine and Steel Fiber

This paper discusses the concept of self‐consolidating concrete mix with Alccofine‐1203, superplasticizer, viscosity modification agent, crimped steel fiber on the RC beam column joint. Totally, eight reinforced‐concrete (RC) column joints with M25 grade concrete were considered in this study. Out of eight RC beam column joints, two beam column joints served as Alccofine, two beam column joint specimens served as Alccofine 5%, two beam column joint specimens served as Alccofine‐10%, and two beam column joint specimens served as Alccofine‐15%. All the RC beam column joint specimens were tested under the compression until failure in the loading frame of 2000 kN capacity. The test results of Alccofine‐10% showed the higher loading capacity than that of Alccofine‐5% and Alccofine‐15% in self‐consolidating concrete RC beam column joints. The percentage of superplasticizer, viscosity modification agent, and crimped steel fiber is maintained. Nonlinear finite element analysis (FEA) to analyse the beam column joint through nonlinear finite element modelling (NLFEM) and the modelling results were compared from the experimental results. The results obtained through ANSYS modelling show good agreement with the experimented results. The deflection ductility of experimental results shows 1.57, and the predicted deflection ductility shows 1.59 in beam column joint with Alccofine‐10%. ANSYS software is validated as appropriate software to predict the study parameters of self‐consolidation concrete in beam column joints.
