Year: 2017, Volume:4, Issue : 1
Pages: 36 - 40
Nowadays, most of the automobiles use roller type ball bearing made up of steel. These bearings tend to produce more stress and arcing. When steel rollers are replaced with ceramic rollers they run with an advantage of no requirement for lubrication. But, it also ends up with high thermal stresses on the rollers confining its usage to lesser load capacity. So, carbon nano tube is reinforced with ceramic to avoid arcing and increase load bearing capacity and the structural analysis are done through ANSYS and the comparison is presented.

Pages: 41 - 46
The concrete elements such as beams, columns, slabs etc., prone to sudden fire break out of fire are subjected to extreme temperatures. Their performance and assessment after exposed to fire becomes necessary to decide upon its fitness and required measures for the repair of different elements. Therefore, it is necessary to understand the changes in the concrete properties due to its exposure to extreme temperatures. It is very essential to know the effect of elevated temperature on the properties of concrete. This paper investigates the effect of sustained elevated temperature on the properties of ordinary concretes of three different grades i.e., M30, M35 and M40 grades, containing 53 grade of cement. The specimens were heated to 1500C, 2500C and 3000C at 1 hour, 2hours and 3hours duration in muffle furnace. They were tested for compressive and split tensile strengths after air cooling to the room temperature. The variables considered in the study include type of cementing material, and temperature. The compressive and tensile strengths of concrete decreased with increasing temperature. And also recron 3s fiber material is used for increasing the strength of the concrete at various temperatures. In this experimental study Recron 3s fiber has been added to concrete in order to enhance the strength characteristics of the concrete in percentages of 0.10%, 0.15%, 0.20%, 0.25%, 0.30%, 0.35% and 0.40% to the weight of concrete and the optimum fiber content for Compressive and Tensile strengths were obtained and it can be used for further study for determining the Compressive and Tensile strengths of the conventional concrete without using recron 3s fiber and concrete with recron 3s fiber material at various elevated temperatures and were observed at 1hour, 2hours and 3hours duration for the age of 7 days to 56 days.

Pages: 50 - 55
It is a substantial fact that specific disposal standard for laundry effluent have not been prescribed by Gujarat pollution Control Board (GPCB). Laundry waste uses soap, soda, detergents and other chemicals for removal of stains, oil, grease and dirt from the soil clothing. The laundry waste is originated in the residential zone on account of manual cleaning, cleaning by domestic washing machines as well as large amount of effluents are generated by commercial washing including dry-cleaning. An attempt has been made in the present investigation to generalize the characteristics of laundry effluent generated by various sources in Vadodara (Gujarat). It has been found during the laboratory studies, that SS, BOD and COD of laundry waste are high. Treatability studies were carried out in the environmental engineering laboratory of B.V.M. Engineering College, V.V.Nagar for removal of these contaminants. The coagulation-flocculation followed by dual media filtration was found to be most suitable sequence of the treatment.
