An experimental research on the polypropylene fiber concrete using ceramic tile waste as partial replacement for coarse aggregate

Abstract

This experimental study describe the combined effect of polypropylene fiber and ceramic tile waste on different strength properties of M40 grade concrete. Conventional concrete have different problems as cracks, voids, bleeding and plastic shrinkage that occurs in concrete specimen. Recent studies shows that polypropylene fiber reduces the effects bleeding and plastic shrinkage and increases the homogeneity of concrete mix. Present investigation is focused on the replacement of natural coarse aggregates with ceramic tile waste at various percentages (10%,15%,20%,25%). Polypropylene fiber is added at proportions of 1% by weight of cement to concrete mix. A number of beams, cubes and cylinders are casted to conducted the compressive strength, flexural strength, split tensile strength test at 7,14 and 28 days. Two non-destructive tests also carried out as rebound hammer and ultra pulse velocity test on cubes. For concrete mix, ordinary portland cement grade 43 and water cementitious ratio has taken 0.4. After the result analysis,the optimum value obtained at 20% replacement of coarse aggregate with ceramic tile waste. Ultra pulse velocity test also reveal that the homogeneity of the design concrete mix is higher than conventional concrete. It makes the concrete more versatile in the construction industry.
