Shivaraj, Shreenivas Reddy Shahapur and P.D. Maneeth

Abstract

Self-compacting concrete (SCC) is known for its high workability and settles, carries and flows by its own weight without any vibration from outside sources. Achieving the good strength without bleeding and segregation of aggregates are most important and tedious process in this concrete. By developing its properties, the well conditioned concrete has been achieved along with high strength of grade M70. Adding mineral substance like fly ash, silica fume, ground granulated blast furnace slag (GGBS) with the cement by 5%, 10%, 15%, 20%, 25% and 30% the qualities of fresh concrete have been investigated. The concrete obeys the guidelines of EFNARC to fulfils the SCC requirements. Numerous mechanical characteristics have been researched, including modulus of rupture, split tensile strength, modulus of elasticity, and compressive strength. From the test results, the concrete has achieved satisfactory performance against the applied load. Also with respect to the durability, higher than normal temperatures of 200, 400, 600, 800 and 1000 (°C) in order to find the behavior of concrete under elevated temperature. Corresponding to the above temperature, the compressive strength test and moisture in the concrete have been studied. From the test results, if the temperature has been increased, the concrete loses its ductility and the surface cracks also have been increased a lot.
