Abstract: The utilization of supplementary cementation materials is well accepted, since it leads to several possible improvements in the concrete composites, as well as the overall economy. The present paper is an effort to quantify the strength of ground granulated blast furnace slag (GGBS) at various replacement levels and evaluate its efficiencies in concrete. Cement with GGBS replacement has emerged as a major alternative to conventional concrete and has rapidly drawn the concrete industry attention due to its cement savings, energy savings, cost savings, environmental and socio-economic benefits. Today's construction industry, use of concrete is going on increasing rapidly............

Abstract: Materials management is a critical component of the construction industry. As such, organizations need to understand the effects of proper materials management techniques on the effectiveness of project execution. A properly implemented materials management program can achieve the timely flow of materials and equipment to the jobsite, and thus facilitate improved work face planning, increased labor productivity, better schedules, and lower project costs. Materials management is an important function in order to improve productivity in construction projects.:...........

Abstract: The main aim of the study was to analyze the NACA0012 wind turbine airfoil at various angles of attack, keeping the Reynolds number constant. The efficiency of the aerodynamic wind turbine is greatly influenced by the aerodynamic efficiency of the airfoil. In the present study NACA0012 airfoil is considered as a suitable wind turbine blade. The geometry and analysis was done using Ansys-Fluent. Calculations were done for constant air velocity altering only the angle of attack.:...........

Abstract: This paper discusses the control of magnetic flux density in active magnetic bearings. The rotor is laminated in which the magnetically active part of the rotor is built with stacks of disk consisting of shaped layers of ferromagnetic sheets which are electrically insulated from each other. The use of different applications of control measures depending on its application, linearity, measuring range, resolution, sensitivity as well as its frequency range causes the output signal of its sensors to change according to its physical effect as a function of the measured quantity during the process of measurements..:...........

Abstract: This article is concerned with the effect of mass and partial slip on boundary layer flow of a nanofluid over a porous plate embedded in a porous medium. By taking suitable similarity variables, the governing partial differential equations are made dimensionless and then reduce to ordinary differential equations with the associated boundary conditions. The equations are then solved numerically using fourth order Runge-Kutta method.:...........

Abstract: Hydroxyapatite Ca10(PO4)6.OH2 (HAp), known for bioactive fixation with the surrounding bone tissues, is one of the most studied and used material for implants. The brittle behavior of HAp due to lower fracture toughness under mechanical loads is improved by addition of a ceramic second phase such as Al2O3, SiC, ZrO2, etc. There is a need to focus on the microstructure of such reinforced biomaterials to understand the relationship between their established mechanical behavior and the microstructure.:...........

The effect of fuel injection pressure on diesel engine performance using B20 blend in comparison with that using neat diesel fuel is studied. Preliminary experiments regarding the analysis of fuel properties indicate that oils are heated up to the temperature of 50–60 °C during process of transesterification. This is necessary to reduce high viscosity of oils as compared with that of neat diesel fuel..:...........

However there are no studies of quality of concrete plant wastewater. and the activities in which water can be used. This paper aim to evaluate the quality of concrete plant wastewater and to propose guidelines for its treatment for non potable application. The type of water used for the mixing did not affect the concrete slump and density. However setting time were found to increase with water quality deteriorating. Because of scarcity of potable water it is very important to use this treated waste water in concrete in our industry...:...........

Abstract: An approach for interactive bi-criteria smoothing of experimental data is proposed using the system (S-G) filter of Salvitzky-Golay. An optimization problem is formulated with the controversial criteria: "total absolute error" and "integral smoothness". For the choice of adjusting parameters of the filter – the degree of the approximation of polynomial and the number of the supporting points is used. A Pareto-optimal solution set is determined for this problem. Then subsets of Pareto-optimal solutions are found by employing the -selection method, which are aranged by their extended efficiency..:...........

Abstract: Rural water supply systems that cover more than one village are becoming increasingly common in India. Multi-village water supply schemes have the potential to capture economies of scale and to facilitate higher levels of service, and they appear to offer a feasible and long-term solution to the acute water scarcity faced by many regions in India. The challenges of providing sustainable access to rural water services in developing countries often go far beyond that of the technology itself. Aghai rural regional water supply scheme includes 24 habitations of Bhiwandi and SahapurTakula............
