    Potential Applications of Marble Dust in Industrial Use by Characterization Techniques – A Review
    (International Journal of Advanced Structures and Geotechnical Engineering, 2016) Srivastava, Anshuman; Bhunia, Dipendu
    Marble is a very common building material. In India, Rajasthan caters almost 85 % of the total demand of marble. It is normally a rich source of calcium carbonate which has various applications. Quarrying, processing and polishing of marble generates large amount of waste. This waste is dumped and left unattended thus creating hazardous problems. It is required to use this waste material in development of some value added products and reducing the impact on environment. Thus it is necessary to know the chemical properties of the waste left behind and how it reacts or helps in the hydration process. It is required to study the current uses of this waste marble dust in various industrial and construction practices. This paper describes various chemical properties of marble dust using characterization techniques like X-Ray Diffraction (XRD), X-Ray fluorescence (XRF), Thermo gravimetric Analysis (TGA) and Scanning Electron Microscope (SEM). Also the practical application of these characterization techniques in studying the chemical reactions taking place in mortars and concrete is reviewed. Suggestions for further studies and utilization in various fields for building a sustainable environment are also incorporated. It would encourage bulk utilization of waste marble dust as an alternative construction material which is otherwise a waste.

    A study on environmental and economic impacts of using waste marble powder in concrete
    (Elsevier, 2017-09) Srivastava, Anshuman; Sangwan, Kuldip Singh; Bhunia, Dipendu
    Gainful utilization of waste marble powder in various construction practices has become a topic of interest in research areas. An overview of works reported regarding the use as partial replacement of sand and cement by marble powder in concrete is presented in the paper. Gaps in the studies to date have been pointed out. An environmental impact comparison of normal concrete with the use of marble powder as partial replacement of cement and sand is carried out using the UMBERTO NXT life cycle analysis software with ReCipe midpoint and endpoint methods. Finally, a detailed cost analysis study has been performed to justify the use of marble powder in concrete which has exhibited encouraging results in terms of strength and quality. It has also been found that the use of marble slurry in concrete reduces its environmental impact and is economically beneficial.

    Analytical and Experimental Investigations on Using Waste Marble Powder in Concrete
    (ASCE, 2019-04) Srivastava, Anshuman; Bhunia, Dipendu
    Research using marble powder as a partial replacement of cement in concrete has gained a lot of attention recently. In this paper,the effect of dried marble powder on particle packing of concrete has been demonstrated. Experimental investigations have been conducted onthe effect of marble powder on hydration reaction, strength activity index, and possible reasons for the gain in strength. In addition, statisticalmethods were used to develop two mathematical models for marble powder incorporated in concrete using experimental values. In the firstmodel, the ratios of 28-day compressive strength between concrete with cement partially replaced by marble powder and control concretehave been related to marble powder replacement percentage. In the second model proposed, modified and simplified relationships for thewater-cement law when cement is partially replaced by marble powder have been provided. The first model was validated for both standardcubes and cylinders used for testing by researchers and the predictions showed only 7.15% error as compared with the experimental values.The second model might serve as a useful tool for mix proportioning of concrete mixes incorporating marble powder in concrete. Finally,based on a review of the literature and experimental results, a set of guidelines has been proposed for the use of marble powder as a partialreplacement of cement in concrete
