Experimental Investigation of Flexural Performance of Sandwiched Engineered Cementitious Composite Concrete Slab and Analysis using ANSYS Software

Engineered cementitious composite (ECC) is an ultra-ductile cement based material reinforced with fibers. It is also called as Bendable concrete. ECC has many capabilities due to its superior properties characterized by high ductility, low permeability and high tensile strength. In this paper, the conventional concrete and engineered cementitious composite concrete are prepared of M30 grade incorporated with polypropylene fiber and sandwiched using steel mesh and the results are being compared and studied. The flexural behaviour of a sandwiched engineered cementitious composite (ECC) is studied and compared with that observed in a conventional concrete. Results of the sandwiched ECC concrete slab test indicate that brittle failures as shear failure and bond splitting failure observed in the conventional concrete slab can be prevented by using PP-ECC in place of the concrete. As a result, the sandwiched PP-ECC concrete slab indicate excellent ductile manner.
