1. EFFECT OF MIXING WATER QUALITY ON COMPRESSIVE STRENGTH OF CONCRETE
B.A. OLAWUMI and T. ABIOYE
Abstract
Mixing water serves as a binding agent between cement and aggregates. Its addition to concrete ingredient results in plasticity of concrete at fresh stage. This paper presents an assessment on the effect of quality of mixing water on compressive strength of concrete using three different types of mixing water such as; drainage water, tap water and well water. A concrete of nominal mix 1:2:4 using w/c ratio of 0.6 was employed to produce concrete cubes of 150mmx150mmx150mm. Three sets of concrete were cast due to three mixing waters adopted. For each mixing water used in the concrete production, 9 cube samples were produced and three curing (hydration) periods were also adopted. These are 14, 21 and 28 days respectively. At each hydration period, three cubes were produced. However, a total of 27 cube samples were cast and tested for mechanical properties (i.e. compressive strength). Thus, at each stipulated curing period, the cube samples were removed from curing tanks and subjected to compressive strength test. The results of compressive strengths of concrete mixed with drainage water (CMD), concrete mixed with tap water (CMT) and concrete mixed with well water (CMW) from this study are 22.44N/mm2, 27.07N/mm2 and 23.64 N/mm2 at 28 days. All the three results are within what is specified in BS 8110 (1997) (i.e. 20-40 N/mm2). This indicated that the three mixing waters can be used from concrete mixes, but tap water which produced concrete with highest compressive strength is the most suitable mixing water. It was also revealed from this study that the densities of concrete in three categories of mixing water at 28 days concurred with Neville (1996) (i.e.2200-2600kg/m3).

P. CHANDRA SEKHAR, M. MAHENDRA BABU
Abstract
The life time of any work piece depends up on its surface properties. Because it is in direct contact with atmosphere. In today‟s manufacturing industries quality is one of the significant factors, the only component to influence the customer to a level of satisfaction. In every industrial sector surface quality is detected by the surface roughness of the component. The demand for high quality aluminium alloys with good surface finish increasing day by day because of newer applications in various fields like aerospace, automobile, die and mould manufacturing and thus manufacturers are required to increase productivity by improving surface quality by avoiding stress concentrators on the surfaces. Some of the parameters which effect the work piece at the time of machining are namely cutting speed, depth of cut, feed and nose radius, cutting environment(dry or wet), etc. The experiment will be carried on three machining parameters, viz., speed, feed and depth of cut as independent variables and the surface roughness parameter as response variable. The experimentation plan is designed by using design of experiment (DOE).This experiment is machined on CNC Turning Machine and the process will be carried on the AL-ALLOY ADC12 Material the measurement of surface roughness will be carried out by using stylus-profilometer. The optimum cutting condition was determined by using the TAGUCHI is one of the optimization techniques for optimizing the cutting parameters. By using TAGUCHI optimizing the cutting parameters for the considered DOE.

P.Sai Naresh Babu, K.Venkata Rao, Ch. Lakshmikanth, P. GoplaKrshnaiah
Abstract
Researchers worked on natural fiber reinforced composites to enhance the material performance. As these natural fibers offer a number of advantages over traditional synthetic fibers. The most attractive advantage is high strength to weight ratio. Glass fiber has been widely known as an engineering material that exhibits high specific performance to cost ratio which accounts for its current dominant role in serving as the major reinforcement material for the global composite market. While, hemp is a commonly used term for high-growing industrial varieties of the Cannabisplant and its products, which include fiber, oil, and seed. In this project the mechanical properties of glass and hemp fiber reinforced hybrid composites were studied. These composites were prepared by using Hand-layup technique while varying weight fractions from 0.4g, to 2g.The specimens are prepared according to the ASTM standards and experiments are carried out by using tensometer for tensile and flexural tests and charpy impact testing machine for impact test. From experimental results it is observed that glass and hemp fiber reinforced composites have higher tensile strength, flexural strength and impact strength compared to the matrix material.

11. DESIGN AND FINITE ELEMENT ANALYSIS OF DIFFIRENTIAL GEARBOX FOR DIFFERENT MATERIAL WITH VARYING LOADS
V.Sunil Kumar, P.W.D.S.Milton
Abstract
Differential is used when a vehicle takes a turn, the outer wheel on a longer radius than the inner wheel. The outer wheel turns faster than the inner wheel that is when there is a relative movement between the two rear wheels. If the two rear wheels are rigidly fixed to a rear axle the inner wheel will slip which cause rapid tire wear, steering difficulties and poor load holding. Differential is a part of inner axle housing assembly, which includes the differential rear axles, wheels and bearings. The differential consists of a system of gears arranged in such a way that connects the propeller shaft with the rear axles. In the present work all the parts of differential are designed under static condition and modeled. The required data is taken from journal paper. Modeling and assembly is done in CATIA. The detailed drawings of all parts are to be furnished. The main aim of the project is to focus on the mechanical design and contact analysis on assembly of gears in gear box when they transmit power at different speeds at 2500 rpm; Analysis is also conducted by varying the materials for gears, Cast Iron, And Cast Steel. The analysis is conducted to verify the best material for the gears in the gear box at higher speeds by analyzing stress, displacement and also by considering weight reduction. The analysis is done in Ansys Workbench.
