ABSTRACT

Present paper focuses on the construction and testing of concrete filled steel tubular section. Concrete in filled Steel tubular section has gained the advantage of composite member. Generally, composite members are constructed using two or more different materials to obtain different engineering properties. Use of steel as an external mould neglects the use of shuttering panels, increases the mechanical properties of the section and neglects the water bath of the section which is often done in curing period. Water bath in one of the important method of curing for vertical structural elements. To reduce such instant, this study investigates the role of PEG400 as a self-curing agent, the percentage of PEG400 by weight of cement is 2% as the dosage of internal curing. The test results were studied for three mixes that is for M20, M25 and M30 mixes. Concrete mixes prepared using internal curing compound PEG400 with specified target strength values calculated during design mix for M20, M25, and M30 grade of concretes.
