Abstract
Abstract: Concrete is the world’s most versatile, durable and reliable construction material. Next to water, concrete is the most used material, which required large quantities of Portland Cement. Ordinary Portland Cement production is the major generator of carbon di oxide, which polluted the atmosphere. In addition to that large amount energy was also consumed for the cement production. Hence, it is essential to find an alternative material to the existing most expensive, most resource consuming Portland Cement.The study describes experimental investigation on flexural behavior of reinforced GPC. A total of eighteen beams were tested. From this, nine were of M20 mix, i.e., conventional concrete beams while nine were of geopolymer concrete,from this nine beams, three beams with the ratio of binder i.e., flyash:GGBS ratio as 75:25, other three with 70:30 while remaining three beams with 65:35. Also, 12 cubes & 12 cylinders were also casted and tested for compressive strength and split tensile strength respectively. From them, three were of conventional concrete while other nine of GPC with three different ratios as mentioned above. The reinforcement was designed considering a balanced section for the expected characteristic strength. All the beam specimens were tested under two point static loading. The studies demonstrated, the study of conventional and geopolymer concrete beams related to deflection, first load at which crack appeared and their crack patterns.
