“…Main advantages of CFST columns are no reinforced cage and no formwork as the steel tube can extremely be used as formwork and they are fire resistant. Based on the various research works carried out, it can be said that circular columns should be preferred over squareshaped CFSTs [4,5], in order to further enhance structural performance and meet various design requirements, the focus of tubular columns [6,7], concrete-filled double-skin tubular columns [8], stub columns with carbon fiber reinforcement polymer (CFRP) wrap material [9][10][11][12], and concrete-filled aluminium columns [13,14]. Such experiments were mainly aimed at using new alloys or modifying standard CFSTcolumn configurations to enhance the structural efficiency of composite columns.…”

Recycling or utilization of industrial waste is becoming more popular as people become more environmentally conscious. Silica fume is a by-product of the smelting process in the silicon and ferrosilicon industries. This study examines the mechanical behavior of steel tubular composite column filled with conventional concrete and silica fume concrete experimentally under axial compressive loading. For the study, variability in steel tube thickness and column height with a constant diameter are considered. To explore the influence of silica fume in concrete, microstructural analyses are carried out by SEM, XRD, and FTIR. The experimental results reveal that the use of silica fume as a replacement of cement is feasible; the silica fume concrete-filled steel tubular (SCFST) column has marginal enhancement strength capacity compared to CFST column as thickness increases.

“…This was manifested in many researches 42,60,64–67 . The expansion process in EPS and exfoliation in EV results in porous nature, thereby resulting in a lesser dense and lower strength aggregates 68 . Nonuniform distribution of the EPS aggregates and petrographic characteristics of EV aggregates in the concrete mix may also have resulted in the lower compressive strength of the resultant concrete.…”

Investigation of mechanical properties and thermal behavior of expanded polystyrene concrete (EPS) and exfoliated vermiculite (EV) concrete has been accomplished in this research. It includes how EPS concrete is prepared by substituting the coarse aggregate with 0, 10, 15, and 20% with EPS aggregates. Similarly, EV concrete is prepared by replacing the fine aggregates with 0, 15, 45, and 60% with EV aggregates. The influence of EPS and EV proportion on mechanical and thermal properties was detected. Thermal properties were studied with an adiabatic box technique. Clear improvement in thermal behavior was observed in comparison with normal concrete and reduction in compressive strength was observed for an appreciable increase in the amount of EPS and EV. Also, the properties like split tensile strength, load–deflection curves, and durability properties of the EPS and EV concretes were experimented.

“…In this regard, several researchers have worked on the use of materials such as rice husk, sugar cane buggas & fiberglass, etc. On addition of a new fiberglass to standard concrete, you should keep in mind the short & long term interaction [3]. Ingredient with other elements, the effect on compression strength, flexural strength, performance, durability, permeability, tensile strength, bonding and uniformity [4].…”

Conventional concrete i.e. the concrete generally has low tensile strength with limited ductility and low resistance towards cracking. The micro cracks that are developed internally are inherent among concrete and can be explained with the help of propagation of that micro cracks due to its inferior tensile strength. Different fibers, added at a certain percentage of concrete known to improve the deformation properties of concrete along with the plasticity against crack resistance, such as flexural strength. Mainly concrete & ferroconcrete research has been moved to steel fibers, and glass fibers have recently become more available, with no corrosion problems associated with glass fibers. This article describes an experimental study of the usage of glass fibers in the structural concrete. High-dispersion CEM-FILL fiberglass of 14 μm diameter with an aspect ratio of 857 was used at a dosage of 0.33% to 1% by weight in concrete and its mechanical properties such as compressive strength, flexural strength and modulus of elasticity.
