Title | : | Experimental Studies On Concrete Utilising Red Mud As A Partial Replacement Of Cement With Hydrated Lime |
Country | : | India |
Authors | : | P.Ashok, M.P.Sureshkumar |
Abstract: The Bayer Process for the production of alumina from Bauxite ore is characterized by low energy efficiency and it results in the production of significant amounts of dust-like, high alkalinity bauxite residues known as red mud. Currently red mud is produced almost at equal mass ratio to metallurgical alumina and is disposed into sealed or unsealed artificial impoundments (landfills), leading to important environmental issues. It comprises of oxides of iron, titanium, aluminum and silica along with some other minor constituents. Presence of Alumina and Iron oxide in red mud compensates the deficiency of the same components in limestone which is the primary raw material for cement production. Presence of soda in the red mud which when used in clinker production neutralizes the sulfur content in the pet coke that is used for burning clinker enrooted cement production and adds to the cement's setting characteristics. Based on economics as well as environmental related issues, enormous efforts have been directed worldwide towards red mud management issues i.e. of utilization, storage and disposal. Different avenues of red mud utilization are more or less known but none of them have so far proved to be economically viable or commercially feasible. Experiments have been conducted under laboratory condition to assess the strength characteristics of the aluminum red mud. The project work focuses on the suitability of red mud obtained for construction. Five test groups were constituted with the replacement percentages 0%, 5%, 10%, 15%, 20% of red mud and 5% of hydrated lime with cement in each series. To achieve Pozzolanic property of red mud, hydrated lime was added. This paper points out another promising direction for the proper utilization of red mud.
Key Words: Cement mortars, Red mud, hydrated lime, monotonic load and Deflection.

Title | : | Material Requirement Planning in Aircraft Maintenance |
Country | : | India |
Authors | : | Binil John, T. Paul Robert |
Abstract: Aviation field always come across a common issue throughout the world while planning their materials in inventory. Cost of maintaining unwanted inventory can hit the revenue of the airline operations. So a near optimal solution is preferred for achieving this. Materials planning can be divided into two models i.e. stochastic and forecasted model. Most of the airlines throughout the world follow stochastic models such as Max-Min, Reorder point (ROP) method, etc. with the aid maintenance software packages widely available in market. It is found that they try to fit the same methodology in almost complex dependent demand products in aviation where demand is discrete. The appropriate method for this scenario i.e. Material Requirement Planning (MRP) is found to be not considered. MRP is nothing but a computerized inventory control and production planning system which helps in scheduling the planned order releases along with appropriate lot sizing.

Title | : | Job Shop Scheduling Problem by Using Genetic Algorithm |
Country | : | India |
Authors | : | K. Suresh, R. Jeya Girubha |
Abstract: In Scheduling is one of the most important issues in the planning and operation of manufacturing system, but the generation of consistently good schedules is more difficult. The difficulty of finding the optimal schedule depends on the shop environment, process constraints and performance indicator. One of the most difficult problems in this area is the job shop scheduling problem (JSSP), which has been proved to be a Non-deterministic Polynomial-time (NP)-complete problem. In this paper, a genetic algorithm based solution methodology has been presented and the algorithm is implemented using powerful Matrix Laboratory (MATLAB) environment to solve and to find a schedule that has lowest possible value of makes pan, where the makes pan is the time required for all jobs to be processed according to a given schedule by using Genetic algorithms.

Title | : | Production of high strength Al-Si Alloy with Various Compositions of Alloys |
Country | : | India |
Authors | : | M.Vishnukumar, M.Pradeep, K.Ramachandran |
Abstract: Within the last few years there has been a rapid increase in the utilization of aluminum-silicon alloys, particularly in the automobile industries, due to their high strength to weight ratio, high wear resistance, low density and low coefficient of thermal expansion. The advancements in the field of application make the study of their hardness and tensile behavior of utmost importance. In this present investigation, Aluminum based alloys containing 12% weight (eutectic range) of Silicon were synthesized using casting method. Compositional analysis and tensile studies of same amount of samples in different composition have shown near uniform distribution of Si in the prepared alloys. The idea behind this work was to see the effect of addition of immiscible alloys for the refinement of microstructure.

Title | : | Wear Behaviour of Coconut Shell Powder and Coir Fibre Reinforced Polyester Composites |
Country | : | India |
Authors | : | Vignesh.K, Natarajan.U, Vijayasekar.A |
Abstract: The experiments are carried out to investigate the wear performance in the coconut shell powder (CSP) and coir fibre reinforced polyester resin composites. Pin-on-disc machine is used to investigate the abrasive wear property of the polymer matrix composites against 400μm grit size abrasive paper with the velocity of 2.0 m/s and the varying load conditions are applied like 5N, 10N, 15N, 20N and 25N. The effect of the coconut shell powder and coir fibre concentration and sliding distance on the weight loss of composites has been analyzed. The result shows that the coefficient of friction increases with the increase of load in the CSP and coir fibre containing polymer matrix composites. It is observed that the wear rate is increases with the increases in the applied load. The wear rate is decreases with the addition of CSP and coir fibre. Whenever the applied load is increases, the friction at the contact surface of the material and rotating disc is also increases. The addition of the CSP and coir fibre is act as reinforcement in the polymer matrix composites. Due to this addition, the wear resistance increases.

Title | : | TRIBOLOGICAL STUDIES ON NANO-CaCO3 ADDITIVE MIXED LUBRICANT |
Country | : | India |
Authors | : | E. Prakash, R. Rajaraman, Dr.K.Sivakumar |
Abstract: CaCO3 nanoparticles with an average size of 285 nm were synthesized via the carbonation method. The tribological properties of the CaCO3 nanoparticles as an additive in lithium grease were evaluated with a four-ball tester. The results show that these CaCO3 nanoparticles exhibit good performance in anti-wear and friction-reduction, load-carrying capacity, and extreme pressure properties. The action mechanism was estimated through analysis of the worn surface with scanning electron microscope (SEM). The results indicate that a boundary film mainly composed of CaCO3, CaO, iron oxide, and other organic compounds was formed on the worn surface during the friction process.

Abstract: In the rapidly changing world the source of power production is mainly established on the conventional source of energy. But due its depletion and its impact on the environment the prevailing source of energy does not meet the energy required for the forthcoming decades. There arises a need of finding an alternate source of energy. This physical exertion focuses on cost effective method of utilizing the renewable and clean energy. Study has been done on different existing flat plate collector's behaviors and compared to reduce the cost of collector. To carry out this the ceramic coated tiles are used to diminish the cost of panel, insulation, maintenance, durability and its life considerations. The investigation presents optical and thermal properties of the collector, which are calculated by using experimentation. The cost of prepared flat collectors is economical and beneficial which is designed, fabricated and tested on the base of the locally available materials and presented in this critique.

Abstract: Globally, industrial technologies are shifting toward the development of new products that are greenhouse gas-neutral, cleaner burning, and more environmentally sustainable. This is being driven by a variety of factors including tremendous advances in science and technology, climate change policies, consumer demand for green products, the rising price of oil, and the discovery of new functionalities of petroleum replacements. In order for the growing interest in developing the replacement of the combustion engine fuel that mainly consider on physical and chemical properties of the fuel change. The combustion of fuel will mainly based on physical and chemical properties of the fuel .The fuel generally having high carbon content and carbon nanotubes also having high carbon content her our idea goes to the fuel and carbon nanotubes mix to produce alternate fuel. The changes of properties will result the fuel burning temperature increases. The fuel having higher calorific value, engine performance increases and emission of co and nox level decreases. and also the fuel will be renewable, sustainable and alternative for compression ignition engines. Combustion engine fuel instead of diesel using biofuels mixing with carbon nanotubes what are all the physical and chemical properties changes refer to the standard fuel value. .Keywords Carbon nanotubes, physical-chemical properties, performance, standard fuel value
