Corrosion Behaviour of Red Mud particulate reinforced Aluminium 6013 composites by Potentiodynamic Polarization[ ]


Metal matrix composites containing Aluminum 6013as matrix are getting considerable applications in the automotive, aerospace and other related areas. Ceramic particulates as reinforcement particles in Al-based Metal matrix composites will have a great influence on corrosion resistance. This research work gives the details of corrosion behavior of Red Mud particulate reinforced Aluminium 6013 composites in neutral medium by potentiodynamic polarization (PDP) techniques using electrochemical work station. Composites are manufactured by stir casting method. Composites of Aluminium 6013 containing red mud particulates with different weight percentage were manufactured. Aluminium 6013 alloy was also casted for comparison. Corrosion rates of composite materials were found to be decreased when compared with that of matrix alloy. Therefore composite materials are more suitable for application in marine engineering than matrix alloy.

Peculiarities of Road Projects' Cost Overruns[ ]


Road projects contribute immensely to the development of an economy, yet they do not come without their own share of challenges; among which are cost overruns. Various scholars have carried out studies on cost overruns, including a few on road projects but the peculiarities of road projects cost overruns are yet to be identified. Do these road projects cost overruns have any similarity across the studies? The identification of the peculiarities could aid in developing specific cost management methods by taking into consideration the nature of road constructions. This study therefore aims at finding the peculiarities of road projects cost overruns from the review of literature. The findings reveal that road projects are prone to cost overruns, they have very large magnitude of cost overruns and the causes of cost overruns vary for all road projects.
