Title

EXPERIMENTAL STUDY ON CONCRETE BY USING MARBLE DUST AND DISMANTLED CONCRETE AS AGGREGATES

Abstract

Concrete is a heart material for any construction in the world. Based on the usage of materials in globe the water gets first place. And the concrete gets second place. The materials used for preparation of concrete is cement, fine aggregate (Sand), coarse aggregates (HBG metal) and water. Normally fine river sand is used for fine aggregates. The scarcity of sand due to more usage in entire global. This scarcity leads to increase the cost and reduce natural sources. Therefore we should use alternative material in the replacing of natural sand. That selected alternative material should satisfy the properties of concrete and should not cause decreases the strength of concrete. Normally Hard broken granite metal is used for coarse aggregates. The scarcity of HBG metal is also occurs due to more usage in global. Out of total volume of concrete more volume occupied by coarse aggregates. Air pollution also occurs due to crushing of granite stones. Therefore the alternative selected materials should not cause environmental pollution. The present experimental study is done on concrete by using marble dust is an alternative material for fine aggregates and demolished concrete as aggregates are alternative materials for coarse aggregates. The concrete main parameters are Characteristic compressive strength, Cylindrical spilt tensile strength and Beam flexural strengths are investigated. In this work M25 grade concrete mix was designed as per IS code mix design. The dimensions of specimens are 150*150*150mm cubes are casted for checking Characteristic compressive strengt. The dimensions of cylinder 300mm length and 150mm diameter cylinders are casted for checking spilt tensile strength. The dimensions of beam 700mm length and 150*150mm cross section beams are casted for checking flexural beam strength. The concrete is prepared by partial replacement of fine sand with marble powder at various percentages are 0%,25%,50%, 75%. And Partial replacement of HBG metal with demolished concrete as aggregates at various percentages are 0%,05%,10%,15%. And evolution of strength parameters of each grade of concrete for each proportion in the form of cubes, cylinders and beams for testing at 7days,14days and 28days periods. The strength parameters of concrete increases with replacement of sand with marble powder and replacement of HBG metal with demolished concrete as aggregates up to 50% and 10% only. Otherwise decreases the strength parameters of concrete. Demolished concrete are used as aggregates which are having irregularities with hardened cement paste. The usage of these aggregates in concrete is effective in good bonding. The usage of marble dust in concrete with size between 75 to 90 microns is effective in filling the pores in concrete.
