Comparison of Calorimetry and NMR Relaxometry Measurements of Epoxy Cure Kinetics

open access: yesJournal of Polymer Science, EarlyView.
Single‐sided NMR monitors epoxy cure in three DGEBA/diamine systems, alongside benchmark DSC measurements. Fitting both datasets to a Kamal‐Malkin kinetic model shows NMR‐derived rate constants typically exceed DSC values, revealing an offset between gelation and chemical conversion.

RC columns externally strengthened with RC jackets

Materials and Structures, 2013
In this paper the behaviour in compression of RC columns externally strengthened with concrete jacketing is analysed and a cross-section analysis of the jacketed member under axial load and bending moment is developed. The focus was to study the effect of confinement of concrete jacket on concrete core and the behaviour of compressed bars with buckling
