A Study on the Behaviour of Flexural Element of Reinforced with Bamboo Strips for Pure Bending Effect

In this research work, investigations have been carried out to find the effect of waste foundry sand in high strength self-consolidated Concrete Filled Steel Tubular (CFST) stub columns. A total of 14 stub columns were tested under monotonic compression load to identify the optimum percentage of waste foundry sand which is an industrial waste. Among 14 specimens, eight specimens with circular cross-section of diameter 100mm and length 300mm and another eight specimens with square cross-sections of sides 100mm and length 300mm.Each seven specimens can be classified into three categories: two hollow steel tubular sections, two plain SCC columns, and ten SCC filled steel tubular sections. The experimental investigations indicate that the utilization of waste foundry sand has a impact on the strength and ductility of the steel tubular sections. Also the steel tubular sections act as external reinforcement which reduces the local buckling and increases lateral stability. When compared with the square columns, the circular columns save 30% of steel. SCC mixes are prepared by varying the cement content with replacement of foundry waste sand. In this work CFST were prepared with 0%, 5%, 10%, 15% and 20% of foundry waste sand replaced with the actual cement content .From the investigation it is noted that the ultimate load of steel tubular stub columns with foundry waste sand is higher when compared to conventional concrete and saves 10% of construction cost. The work proposes the solution for effective industrial waste management which reduces the environmental hazard and make an eco-friendly environment.
