The experimental investigation was carried out to study and investigate the behaviour of hollow, Plain Cement Concrete (PCC) and Silica; Quartz replaced concrete in-filled medium light gauge columns subjected to axial loads. The cold formed sheets were continuously welded at the middle along its length. The basic study for the in-fill materials were carried out initially. For PCC in-fill M40 grade concrete was chosen. A total of 4 columns of 1.50m length were tested, without in-fill, with plain concrete in-fill and with Quartz and Silica in-fill having a cross section of 100 × 50 × 2 mm. All the specimens were tested to failure. Ultimate load, Load-Axial shortening and Load-Strain for all the specimens tested were plotted. With the comparison of hollow columns the Quartz concrete in-filled columns take around 50% more ultimate loads when loaded axially. The in-filled column with Quartz withstands the maximum load; this is due to the fineness modulus property of the material. The Euro Code 4 predicted the ultimate loads closer to that of the experimental loads. Thus Quartz sand can be used as an alternate filler material.
