Abstract: The difference in the construction cost of concrete and bituminous roads has narrowed down considerably on account of sudden rise of cost of bitumen. Now a day's cement concrete Roads are more preferred than bituminous roads in urban cities in India. Concrete roads are potential users of Cement. The behavior of concrete, whether fresh or hardened, depends basically on the behavior of its components and the relationship between them, therefore, obtaining a concrete with certain properties depends fundamentally on the concrete mix design.

Abstract: Now a days latest manufacturing sectors facing difficulty with two different categories of processing of parts like semi-finished jobs and finished jobs. In literature it is assumed that, for machine scheduling models, either there is infinite number of handling or carrier systems for the job to reach desired location or jobs are distributed on the spot from one workstation to other without travel time involved. Further it is observed that simultaneous scheduling of machines and AGVs in the FMS environments involves certain exceptional difficulties as they are treated as NP hard problems...............

Abstract: The main purpose of this paper is the development of low cost housing structures, in rural as well as in urban areas. In present scenario, the cost of construction of houses is going to be high, so it is difficult to make their homes at low cost especially for rural population. The clay bricks are generally high in cost and create pollution during burning process in kiln. So, in this paper, the reuse of fly ash and foundry sand is done as replacement of major amount of clay which will reduce the cost as well as pollution. No burning is required while making of this brick. For economic construction...............

Abstract: Limiting lateral displacement is a very important factor in the design and construction of high-rise buildings. This movement is limited by stresses induced in the structure and by the comfort of inhabitants at upper floors. Traditionally, structural bracing through the addition of shear walls and other lateral load resisting elements, in addition to many other methods such as Tuned Mass Dampers (TMD), have been used to reduce lateral displacements. Based on the elastic characteristics of an oscillating spring, this work evaluates the use of high stiffness springs implanted at various locations in a structure and analyzed to check their influence on lateral displacement reduction.................

Abstract: The duplex steels are widely used in the area of oil exploration, both in structure and equipment. These steels provide excellent mechanical properties combined with excellent corrosion resistance. The welding of this material takes into account the loss of alloying elements, which are directly linked to the excellent properties of this material, this loss being compensated by the addition of metal during welding. In an autogenous weld, this addition of material to balance the loss is eliminated, and under these conditions, a study subjecting the duplex UNS S31803 steel to this process, a relationship between the microstructure of the weld region and an electrochemical characterization, will be shown that this loss does not interfere with the quality of the weld and the resistance of the material to corrosion.

Abstract: As construction industries are increasing at faster rate consumption of naturally available sand is more now-a-days. The fine aggregate which we use for construction is available from natural rivers and streams use of large amount of fine aggregate affects the environment. This present study had been carried out to investigate the possibility of utilizing a broad range of concrete raw materials as partial replacement for fine aggregate in the production of concrete. In this study replacement of fine aggregate with steel slag, M-sand and bottom ash with 10%, 20%, 30%, 40%and 50% for grade of concrete M30are............

Abstract: Pervious concrete is a special high porosity concrete used for roads carrying light traffic, allows the water from precipitation and thereby reducing the runoff from a road surface and hence recharging ground water levels. Objective of this research is to find mechanical properties i.e. compressive strength, split tensile strength and flexural strength of the pervious concrete. The main problem of pervious concrete pavement is the strength itself. The conventional and pervious concrete is tested for 28 days of curing period with fresh water & salt water. For conventional concrete the mix proportion is considered...........
