Experimental Study on Mechanical Properties of High Strength Concrete for M60 Grade Concrete

This paper presents about the determination of the mechanical properties (compression, split tensile and flexural tests) of the specimens (cubes, cylinders and beams). The specimens are of M60 grade high strength concrete which include fly ash as the partial replacement (in percentage) of cement and Msand as complete replacement of Fine aggregate along with the polypropylene fibers using Glenium 8233 as superplasticizer. The tests are conducted after 7, 14 and 28 days of curing period. The replacement of fly ash was done at different percentages of cement content 0 %, 10 %, 20 %, 30 %& 40 %. Finally after the tests on the specimens after the curing period it is noticed that 20 % replacement of fly ash gave the better strength for the cube and cylinder specimens and 40 % replacement of fly ash for cement for the beams.
