INTRODUCTION Concrete is a mixture of cement, coarse aggregate, N Sellakkannu1, Roshini P fine aggregate and water. Concrete is good in The production of cement results in emission of many compression and weak in tension. The major greenhouse gases in atmosphere, which are responding disadvantages of concrete are brittleness and crack properties for global warming. The waste material formation which decreases the strength and durability having cementing properties which can be added in of structure. cement concrete as partial replacement of cement, The different types of concrete are lime concrete, without compromising on its strength and durability, asphalt concrete, gypsum concrete, polymer concrete, which will results in decrease of cement production high performance concrete and nano concrete etc., lime thus reduction in emission in greenhouse gases. The ground granulated blast furnace slag (GGBS) is a waste product from the iron manufacturing industry, which Volume IX Issue V MAY 2020 Page No : 376 Science, Technology and Development ISSN : 0950-0707 may be used as partial replacement of cement in waste material has been emphasized. Partial concrete due to its inherent cementing properties. In replacement of cement by varying percentage of marble this study Ground Granulated Blast Furnace Slag dust Powder powder reveals that increased waste (GGBS) was partially replaced as 0%, 10%, 20%, 30%, marble dust powder ratio result in increased and 40% in place of cement in concrete. Concrete are workability and compressive strengths of the concrete made for M -30 mix and the cubes, cylinders and Marble Dust Powder is settled by sedimentation and prisms are casted for 7, 14 & 28 days of age in order to then dumped away, which results in environmental find out the optimum percentage of replacement of contamination, in addition to forming dust in summer GGBS in concrete. and threatening both agriculture and public wellness.. In this research work, Marble Dust Powder has Chaithra H, Pramod K, Dr.Chandrashekara replaced the (OPC & PPC) cement accordingly in the Concrete is the most widely used construction material reach of 0%, 5%, 10%, 15% 20%, & 25% by weight of in civil engineering industry because of its high M-20 grade concrete. Concrete mixtures were structural strength and stability. The concrete industry developed, tested and compared in terms of is constantly looking for supplementary cementitious compressive strength to the conventional concrete. The material with the objective of reducing the solid waste purpose of the investigation is to analyze the behavior disposal problem. Ground granulated blast furnace slag of concrete while replacing the Marble Dust Powder (GGBS) and Quarry sand (QS) are among the solid with Different proportions in concrete. wastes generated by industry. The global consumption of natural sand is too high due to its extensive use in Ranjan Kumar, Shyam Kishor Kumar concrete. The demand for natural sand is quite high in The waste generated from the industries cause developing countries owing to rapid infrastructural environmental problems. Hence the reuse of this waste growth which results supply scarcity. This paper material can be emphasized. Marble Dust Powder describes the feasibility of using waste in concrete (MDP) is a developing composite material that will production as a partial replacement of cement and sand. allow the concrète industry to optimise materiel use, The cement has been replaced by GGBS in the range of generate economic benefits and build structures that 30%, 40% and 50% by weight of cement, quarry sand will strong, durable and sensitive to environnement. in the range of 40%, 50% and 60% by weight of cement MDP is by-product obtained during the quarrying for M40 grade mix. Slump test was carried on fresh process from the parent marble rock; which contains concrete while compressive strength, split tensile high calcium oxide content of more than 50%. The strength and flexural strength were carried on hardened potential use of MDP can be an ideal choice for concrete. The cube, beams and cylinders are tested for substituting in a cementitious binder as the reactivity compressive, Flexural and tensile strengths. It is found efficiency increases due to the presence of lime. In this that by the partial replacement of cement with GGBS research work, the waste MDP passing through 90 and sand with Quarry sand helped in improving the microns, has used for investigating of hardened strength of the concrete substantially compared to concrete properties. Furthermore, the effect of different normal mix concrete. These tests are carried out to percentage replacement of MDP on the compressive determine the mechanical properties of concrete up to strength, splitting tensile strength (Indirect tensile 7, 28, 56, 90 days for compressive strength, 28 days for strength) & flexural strength has been observed.
