Micro-Structural Characterization of the bond strength capacity of adhesive material in the alternative of cold-formed steel frame system

Abstract

The introduction of adhesive material in the structural connection of cold-formed steel (CFS) as alternative connection material has a great deal on the strength capacity of bonded joints. This paper evaluates the microstructural characterisation on CFS connection. Two different types of adhesive material, A-SK, and A-3M are taken. The experiment is made to get mechanical properties and is followed by classifying incidence x-ray diffraction (XRD) and scanning electron microscopy (SEM) to study the behaviour inside the adherence. The specimen was penetrated to classify layer surfaces, to present the structural component and to get their morphology. The result is that both materials have similar bonded joints strength capacity which meets the required standard. Quartz and calcite on A-SK are mainly located on the innermost surface separately, while A-3M mostly mixed close to the base steel. In that matter, they have been beneficial for knowing the wide variety of structural characterisation by their elemental composition phases.
