Abstract: This experimental study demonstrates that metakaolin (MK) & Micro Silica(MS) can be successfully used as an admixture in the preparation of self-compacting concrete (HSSCC). In order to prepare suitable mix proportions for different grades of MK based HSSCC, investigations were undertaken replacing cement with 0%, 10%, 20%, 30%, 40% of MK As per the European guidelines for Self-compacting concrete, slump flow test, V-funnel test and L-box test have been carried out on fresh properties of MK based HSSCC. The compressive strength, split tensile strength and flexural strength of the specimens have been analyzed for 7-days and 28 days curing...........

Abstract: Jute geotextile has become a promising and challenging field of interest for the Civil Engineers in the recent years. Use of jute geotextile as an alternative of synthetic geotextile is increasing by a great extent in present days because of its availability and effectiveness in the countries like Bangladesh and India. Use of Jute geotextile instead of synthetic geotextile is cost effective. So a major project is undertaken jointly by India and Bangladesh for the promotion of Jute Geotextile.The effectiveness of Jute Geotextile depends on several properties of jute sample.

Abstract: Magnesium (Mg) and its alloy are potential material for biodegradable implants which makes promising due its mechanical properties. However, corrosion of these metals alloys is too quickly results in losing mechanical integrity. The problem had risen in scientific committee to solve/reduce the corrosion rate and enhance the biocompatibility of the Mg-alloy. In order to reduce the corrosion, surface was modified with the hydroxyapatite (HAp) coating. The synthesis of HAp on Mg-alloy substrate was carried out by an electrodeposition method i.e., chemical deposition............

Abstract: Typically, in order to prevent the rainwater flooding of populated areas and limit the large water circulation in pumps for power plants, flooding of farmland, the propeller pumps used primarily introduced for drainage and sewage treatment are consist of large suction casing, impeller, discharge casing, and motor. When the main shaft and the impeller rotate and driven by an electric motor, the fluid sucked through the suction casing has the principle to be sent to the outside through the impeller and the guide vane. At this time most of the propeller pump that have T shape, severe vibration and vortex the drop of efficiency of the pump. Therefore, in this paper, we increased the mechanical efficiency through the change of the design and through the numerical methods for the impact and efficiency on the lift flow characteristics, the Reynolds number was derived and the feasibility of reducing turbulence and vibration was analyzed.............
