Apart from strength and ductility, adequate bond between steel and concrete at the interface is important in concrete filled steel tube (CFST) columns to ensure a composite action. One way of improving the bond strength of a CFST column is introducing internal stiffeners. This paper presents an experimental investigation into the bond strength of a CFST column with tab stiffeners by conducting a push out test. Twenty-one square specimens of sides 200 mm × 200 mm, fabricated from 2 mm thick mild steel sheeting were tested in two series. The first series considered the variation in the tab spacing along the stiffeners, namely 75, 100, 150, and 300 mm, while in the second series, the concrete cube compressive strengths were 36, 40, and 50 MPa. The bond strength at the concrete–steel interface was found to increase with decreasing tab spacing. In-filling the tubes with higher strength concrete had also resulted in an increase in the bond strength by up to an average of 40%.

The temperature and concentration play an important role on rheological parameters of the gel. In this work, an experimental investigation of thermorheological properties of aqueous gel Carbopol Ultrez 20 for various concentrations and temperatures has been presented. Both controlled stress ramps and controlled stress oscillatory sweeps were performed for obtaining the rheological data to find out the effect of temperature and concentration. The hysteresis or thixotropic seemed to have negligible effect. Yield stress, consistency factor, and power law index were found to vary with temperature as well as concentration. With gel concentration, the elastic effect was found to increase whereas viscous dissipation effect was found to decrease. Further, the change in elastic properties was insignificant with temperature in higher frequency range of oscillatory stress sweeps.
