STUDIES ON STRENGTH OF CONCRETE BY PARTIAL REPLACEMENT OF SAND WITH SAWDUST

IJAERS/Vol. IV/Issue III/April-June, 2015/01-03

Authors: *K.Ambiga, P.Meenakshi

ABSTRACT
This project work on the use of sawdust in production of solid concrete cubes was carried out in order to investigate a possible solution. The project work understudies the weight vis-a-vis compressive strength. Production of solid concrete cubes was made by partial replacement of sand with a varying proportion (10%, 20%, 30%) of sawdust. The strength of each block was determined to ascertain conformity with the minimum acceptable standards. Equally, the weights were checked and compared with blocks devoid of sawdust. The tests were carried out on the 7 and 28 days after production. From data gathered, recommendations were given which will be beneficial to the construction industry and general populace in respect of low cost and light weight concrete cubes.

REMOVAL OF HEAVY METAL FROM INDUSTRIAL WASTE WATER

IJAERS/Vol. IV/Issue III/April-June, 2015/04-08

ABSTRACT
Heavy metals, when in abundance, can be very toxic to the medium in which it is dissolved. Adsorption has been used as a suitable water treatment process to remove heavy metals. For this research, sweet lime and Lemon skin were used as the adsorbent to remove, Chromium wastewater. Batch test &the fixed bed column experiments were then followed, as they simulate the filtration process which is the most commonly used in treatment plants for adsorption. The studies on adsorption were conducted by varying various parameters such as contact time, pH, amount of adsorbent, particle size, concentration of adsorbate and temperature. The adsorption capacity was found to be pH dependent. Results have used Freundlich and Langmuir equations to fit the experimental data so that kinetics of the process can be obtained.

THE EFFECT OF MORALITY ON GEOPOLYMER CONCRETE

IJAERS/Vol. IV/Issue III/April-June, 2015/09-12

ABSTRACT
The major problem that we are facing is environmental pollution and depletion of our non-renewable resources. The concrete is widely used material all around the world and for making the concrete the cement is required and in the manufacture of cement the large amount of carbon dioxide is emitted due to the burning of fossil fuels thus creating the pollution. So for sustainable development we have to replace the cement with the material which is eco-friendly. In this project fly ash, sodium hydroxide, sodium silicate, coarse sand and coarse aggregate are used as the ingredient. The fly ash react with sodium hydroxide and sodium silicate to form sodium alumino silicate. Thus sodium alumino silicate act as binder and bind the coarse sand and coarse aggregate. The polymerization reaction does not start at room temperature so it is necessary to keep the cube in oven.

NUMERICAL AND EXPERIMENTAL INVESTIGATION OF REPLACING VEHICLE SHEET METAL ROOF BY COMPOSITE FOR WEIGHT AND COST REDUCTION

ABSTRACT
The research and development of ecological technologies for cars is becoming increasingly important for the automotive industry. It is seen as one of the greatest trends of this century to conserve natural resources and minimize air pollution. One of the ways of achieving this is by reducing the weight of vehicles and therefore lowering the rate of fuel consumption so that it will reduce the emissions and cost. By reducing the mass of the vehicle, the inertial forces that the engine has to overcome are less, and the power required to move the vehicle is thus lowered.
The economic advantage of weight reduction of vehicles by substituting plastic or composite for steel is considered. As demonstrated, each of proposed lightening route, by plastic and composite combined with recycling at the end of product life, would result in significant economic benefits for the customer by complete returning of the investment in lightening.
During a crash event, a number of structural components must sustain abnormal loadings in order to meet stringent integrity requirements. At the same time other components must dissipate impact energy in a controlled manner that limits the deceleration of a vehicle to a required safety limit.
Real roof crush tests, quasi-static or dynamic, have been widely used to evaluate the safety integration of vehicle structure, especially in the USA, where there are specified standard such as FMVSS 216and IIHS standards.
Model predictions are validated on component level by comparing model behavior by using three-point bending tests. Further modification of the design may be necessary to improve the response beyond the peak quasi-static test force.

PERFORMANCE ANALYSIS OF A HANDLE BAR USING FINITE ELEMENT METHODS TO ENHANCE THE STRENGTH

ABSTRACT
Majority of Indian population depends on a two wheeler for their transportation due to economic reasons. Because of improper design of vehicle and bad road conditions, people in the age group of 30 to 45 years have pains developed in their body. The percentages of people having musculoskeletal pain problems are found to be 13.33%. Designing the handle bar assembly of a two wheeler holds many challenges together with valuation of the structural strength of the mating components. While the handle bar is subjected to buckling, the housing and the other frame experiences tensile, compressive and shear stress. The situations during braking and the forces generated due to road bumps and pot holes can increases the problem. FEA and experimental tests are good methods for novel product development. FEA methodology can be used to decrease design cycle time, quantity of prototypes and more importantly testing time and its related charges. The Aim of this seminar is to improve a design and a prototype for a handle bar assembly of two wheeler which come across strength requirement. The handle bar vibrations can be contained within the prescribed limits using computational methodology for problem solving. CAE software such as HyperMesh as a pre-processor, MSC Nastran or Radioss as a solver and HyperView as a post-processor are considered for this dissertation work. Using this methodology, nature, amplitude, and frequency of the vibrations can be predicted during the design phase. Material properties, thickness for the handle bar and the associated boundary conditions with the adjacent parts are fed into the computing interface while input and output conditions are assigned in the appropriate dialogue box of the software interface. Mathematical modeling shall provide as a preliminary tool for investigation. Physical experimentation shall offer as a source for validation being used as an alternative methodology for finding solution. The physical setup for the existing case shall be used for experimental investigation and validation. .
