Experimental Analysis of Strength and Durability Properties of Self Compacting Concrete with Steel Fibre – Comparision

Abstract

Self-compacting concrete (SCC) is a flowing concrete that greatly improves flow ease and rate by using super plasticizers and stabilizers. Without separating the coarse aggregate, it compacts into every portion of the mold or formwork with just its own weight.The current study focuses on the durability SCC of two phases. SCC mixes with and without steel fibers for the various grades (M20, M30, M40 and M60) are created in the first phase.Initial Surface Absorption Test (ISAT) and Chemical Resistance were used to assess the Steel Fiber Reinforced Self Compacting Concrete (SFRSCC) blends durability performance in addition to their compressive strength. The mechanical properties like compressive strength of the different grades were studied.It can be seen that the 28 days compressive strength of plain SCC mixes like M20, M30, M40 and M60 are 26.8 MPa, 38.8 MPa, 51.1 MPa and 66.8 MPa. When Steel fibers are added, the strength observed is 29.6 MPa, 42.4 MPa, 53.6 MPa and 68.4 MPa that are, an increase of 10.44%, 9.27%, 4.89% and 2.39%.
