An Experimental Study on Strength Properties of Hybrid Fiber Reinforced Self Compacting Concrete
Authors(2) :-Sachin S, Raghavendra D
In early days normal concrete is difficult to place and compaction is required, after using the self-compacting concrete gained popularity due to its higher workability and flowability which reduces compaction. In this study focuses on strength properties of hybrid fiber reinforced self-compacting concrete (combination of crimped steel fiber and polypropylene fiber), combination of these fibers have been tried which effects strength and other properties in different ways. Total fiber content of 0.5%( with steel fiber dosage of 0.3% and polypropylene fiber dosage of 0.2%) was kept constant which results in increasing compressive strength and improvement in flexural and tensile strength which results durability aspects such as shrinkage, bleeding, segregation and the corresponding properties of normal concrete were studied. The age at loading of concrete 7 and 28 days curing for cubes, cylinders and prism. To achieve better work ability and flow ability Super plasticizer of Master Glenium Sky 8630 of 1% for normal concrete and 1.5% for hybrid concrete. Cement has partially replaced by 30% of fly ash, 30% of GGBFS and 10% of micro cement. Workability was reduced when polypropylene fiber used. Addition of increasing super plasticizer dosage from 1% to 1.5% gives work ability and flowability. The study is done for a M40 grade of concrete was designed by using Nan su with w/c of 0.40. Some of the tests conducted on slump flow, L and U box and V funnel to determine the parameters for self compactability of mixtures.
