01-May16  Fabrication & Characterization Of Pr0.7Ba0.3-xKxMnO3 (0≤x≤0.1)

AUTHORS – Dr. Kirti Vishwakrma , Er.K.C.Priydarshi

ABSTRACT : Material science and engineering is at the core of the wide variety of specialized technologies that have been developing over several decades. Development of better and smaller material is the requirement of current computer age for memories, sensor, data storage, processing and probing. Depending on the origin, uses or morphology materials can be divided into various categories. The number of applications and properties and combination of these seems almost unlimited. One prime example of a small but diverse group of material is the perovskite family. Physicists, Chemists and material scientists have shown a wide interest in these materials, because of properties such as high temperature, colossal magneto-resistance and Ferro electricity. Manganite perovskite has attracted considerable attention worldwide due to their peculiar physical properties and potential application. Complete spin polarization due to their half metallic character can be a significant utility factor in the spin based electronic industry. Advances in atomic – and nano-scale growth and characterization techniques have led to the production of modern magnetic materials which reveal a range of fascinating phenomena [1]. These phenomena driven from the fact that electron have spin as well as charge, giving an extra level of complexity to the physics, and an extra degree of freedom in design.

03-May16  LABORATORY ANALYSIS OF CEMENT CONCRETE PREPARED WITH EGG SHELL ASH

AUTHORS : Mr. Praveen Kumar , Mr. Amit Viswakarma  , Mr. Kapil Soni

ABSTRACT : The Infrastructural development is increasing day by day, so the need of concrete is also increasing. In this developing world, many countries are going to urbanization due to population growth. Since India is one of developing countries, the construction will grow in the future. The carbon dioxide produced by cement industries causes environmental pollution and global warming. In 1000Kg of cement manufacturing processes approximately 900Kg of CO2 is emitted. In order to reduce the impact of cement production on atmosphere, waste by products is used as admixture in this study, so that environmental pollution and natural resources consumption can be reduced. Chicken egg is one of the waste materials which generated from the industry and it is contributed to the environmental and disposal problem due to eggshell is increasing continuously in recent years. Therefore, reuse eggshell as an additive in concrete is a better solution to reduce the environmental problem. These eggshells must be grinded into fine powder and then burnt in muffle furnace to form egg shell ash. In the present study, this egg shell ash as a waste is used as a partial replacement of cement and properties like workability and compressive strength were determined. The experiments were carried out into six proportions which are 0% as a control, 5%, 10%, 15%. 20%, 25% and 30% with replacement with cement by weight. The objective of the experiment is to determine the performance of eggshell powder ash in term of its engineering properties. The findings suggested that the suitability of eggshell powder with different proportions is applicable in the structural design of the buildings.

04-May16 STATUS AND FEASIBILITY OF USING RECLAIMED ASPHALT PAVEMENT (RAP) FOR CONSTRUCTION OF NEW ROADS IN INDIA

AUTHORS : Er. Dhananjay Kumar Singh, Prof. Rajesh Joshi

ABSTRACT
Roads play an important role in overall development of any country. A good road network is a key for rapid growth of economy of a country. Road network in India aggregates to about 4.2 million kilometers. This extensive road network, the second largest in the world only after US, caters to about 65 per cent of the freight traffic and 87 per cent of the passenger traffic. National Highways (NH) constitute about 70,934 kilometers which is only 2 percent of the total network. However, it caters to nearly 40% of the total road traffic. State Highways (SH) and Major District Roads (MDR) together constitute the secondary system of road transportation which contributes significantly to the development of the rural economy and industrial growth of the country. In India, milling of distressed pavements or recycling of pavements is rarely practiced and are generally land filled if it is executed at the least in some projects. Reclaimed asphalt pavement (RAP) is a degenerated bituminous pavement that has been recovered, usually by milling top few centimeters of distressed flexible pavements. By using RAP, we can reduce waste production and resource consumption. Reclaimed Asphalt Pavement (RAP) is an innovating technique in India, and the use of RAP is gradually increasing popularity. Using RAP does not only help in minimizing the budget of project but also ensures proper utilization of material. The use of recycled materials like RAP is a key component of sustainable practices in the pavement industry. The objective of this study is to understand the vitality of using RAP for the construction of bituminous pavements. This paper discusses the methods available for milling, status and advantages of utilizing the reclaimed materials in Indian roads.
