Jondhle College of Engineering and Technology, Asangaon Abstract- This paper presents the study of concrete mix design using marble powder. The disposal of marble powder from the marble industry is one of the environmental problems today. The places where marble is used for various purposes, the use of marble powder can be included for construction purpose Marble powder is produced from processing plant during the sawing and polishing of marble blocks and about 20 25% of the processed marble is turned into powder form. Disposal of the marble powder material from the marble industry is one of the environmental problems worldwide today. The replacement is done partially in various proportions and its effect on properties of concrete is studied. The optimum percentage for replacement of marble powder to attain the maximum strength is 50% replacement where as in tensile strength the optimum strength is achieved by 10% replacement by cement. As the percentage replacement of marble powder increases the workability reduces. The use of marble powder reduces the cost of construction as it used in mixing with concrete for building of floors and other structures and it also reduces the proportion of water cement ratio. Index Words: Marble powder, compressive strength, tensile strength, w/c ratio I. INTRODUCTION: Civil engineering is a professional engineering discipline that deals with the design, construction and maintenance of the physical and naturally built environment, including works like roads, dams, parks and recreation, bridges etc. It is broken into several subdisciplines including environmental engineering, geotechnical engineering, infrastructure and construction techniques and many more. Development of city is governed by its infrastructure. This project deals with the advanced construction technique by concrete technology replaced by different waste materials. Concrete is an essential building material that is widely used in the construction of infrastructure such as buildings, bridges, highways, dams and many other facilities. The production of ordinary Portland cement produces 7% approximately of the total greenhouse gas emitted to the atmosp here. Waste marble powder is generated as a byproduct during cutting of marble. The waste is approximately in the range of 20% of the total marble handled. The waste generated every year is in tones, which is dumped in open space. This leads to serious environmental and dust pollution. This may also lead to contamination of underground water reserves [2].The environmental problems attributed by waste marble powder imposes threat to ecosystem, physical, chemical and biological components of environment. It is therefore very important to reuse the waste marble powder which shall solve most of the problem. This report describes the feasibility of using the waste marble powder as a partial replacement of cement. II. SCOPE AND OBJECTIVE To find economical solution for high cost construction material. To study the effect of use by partial replacement of cement by marble powder. To compare the compressive and tensile strength along with variation in w/c ratio. III. LITERATURE REVIEW: Aalok D et al., 2014 studied on Experimental study on use of marble dust in concrete and concluded that for M 25 grade concrete the compressive strength of cubes is increased when 50% of marble powder is added and further any addition of waste marble powder the strength gradually decreases. The split tensile strength of cylinders are increased with addition of waste marble powder up to 25% and decreases on further addition. The flexural strength is obtained at 50% of marble powder mix. Rakesh Gupta et al., 2014 studied on Partial replacement of cement with marble powder and concluded that for M 20 grade concrete the compressive strength of cubes are increased with addition of waste marble powder up to 10% replace by weight of cement and further any addition of waste marble powder the compressive strength decreases. The split tensile strength of cylinders are increased with addition of waste marble powder up to 10% replace by weight of cement and further any addition of waste marble powder the split tensile strength decreases. Abdullah Anwar et al., 2014 studied on Study of compressive Strength of concrete by partial replacement of cement with marble dust powder and concluded that marble dust powder has a potential to provide an alternative to cement and helps in maintaining the 102

2 surroundings every bit well as economical balance. The compressive strength properties of concrete containing marble dust powder at 0%, 5%, 10%, 15%, 20% and 25% of Portland cement. The investigation was primarily to determine a resolution to the disposal problem of marble dust by making usage of it in concrete production for sustainable construction development. The result obtained for 28 day compressive strength confirms that the optimal percentage for replacement of cement with marble dust powder is about 10%. This will post less on the production of carbon dioxide and solving the environmental pollution by cement production, thereby enhances the urban surroundings. Jashandeepsingh et al., 2015studied on Partial replacement of cement with waste marble powder with M 25 grade and concluded that up to 12% replacement of cement with waste marble there is an increase in all mechanical properties. The replacement of 12% of cement with waste marble powder attains maximu m compressive and tensile strength. The optimum percentage for replacement of marble powder with cement is almost 12% cement for both cubes and cylinders. To minimize the costs for construction with usage of marble powder that is freely or cheaply available. To realm of saving the environmental pollution by cement production being our main objective. Pooja J. Chavhan et al., 2014 studied on To study the behaviour of marble powder as supplementary cementitious material in concrete and concluded that compressive strength increases with increase of marble powder. The maximu m 28 days spilt tensile strength was obtained with 45% marble powder replaced with fine aggregate where as in case of compressive strength the strength was gained by replacement of 30% along with replacement of sand by 45-50%. The marble slurry utilization in black cotton soil is one of the best ways to improve soil properties and to protect the environment up to some extent from the harmful effects of disposal of marble slurry in land and water. Veena G. Pathan et al.,2014 studied on Feasibility and need of use of waste marble powder in concrete production and concluded that the investigation revealed that replacing of cement with marble waste powder up to 20% reduces the slump of concrete mixes, whereas replacement of sand by marble waste powder up to 20% enhances the slump of the concrete mixes. In concrete production replacement of 5% cement by marble waste powder gives comparable compressive and flexural strength as of marble waste free concrete specimens, but increasing the replacement range beyond 5% results in strength reduction. In concrete production, replacing of sand up to 20% by marble waste powder gives similar strength as of concrete mixes with 100% sand both at early and latter ages. On the basis of the earlier experimen t al studies the unit weight of the concrete increased due to the high specific gravity of WMD and also filler effect of marble dust because it has finer particles than fine sand aggregate. As a matter of fact marble dust had a filler effect and played a noticeable role in the hydration process. Cement being kept constant it is an expected outcome that an enhancement in the mechanical and physical properties has taken place by virtue of the marble dust s contribution to the hydration process. The porosity of the concrete decreased and UPV increased with increasing percentage of marble dust addition. IV Comparative charts on strength of concrete: The compressive & tensile strength is checked by varying the percentage of partial replacement of cement with marble powder with respect to different water cement ratio.

CONCLUSION: Based on the study the following conclusions are drawn: The compressive strength is increases at 0.4 w/c ratio, but decreases the tensile strength. The partial replacement of cement by marble powder is used up to M25 grade concrete. The strength decreases beyond the use of M 25 grade, but shall be improved on the addition of super plasticizer. As per the comparative study on use of super plasticizer the strength is increased by 2% for M30 in 28 days, whereas by using only marble powder the strength increases by 9% for M25 with 0.4 w/c ratio in both the cases. Use of super plasticizer with marble powder as a partial replacement of cement in higher grades shall be useful for high rise structure to reduce the economy. REFERENCES [1] Aalok D. Sakalkale, G.D.
