Abstract: The durability performance of reinforced concrete is influenced by those physical characteristics of concrete that controls the diffusion of gases and or liquid through its pores. These physical characteristics depend on the chemical composition and the microclimatic condition of the environment. In the present paper, properties of concrete made with Condensed Silica Fume (CSF) blended cement were characterized in terms of physical and chemical composition at early-age. In addition, the effects of inland exposure condition on the durability performance of the concrete were...........

Abstract: Today the aim of the manufacturing companies is to reduce all types of wastes which are; man, money, material and mechanical their properties through the system simplification, organizational potential by using modern techniques. To remain the market leader many types of refinements are used to make the product cheaper and system efficient. Now day, various automotive and cycle industry starts to use the plastic components instead of different costly and heavy metals. So in the chaotic scenario the natural fiber composites are widely used for this addible purpose..

Abstract: The Analytical Strip Method (ASM) for the analysis of thin isotropic cylindrical shells is presented in this paper. The system of three governing differential equations for the cylindrical shell are reduced to a single eighth order partial differential equation (PDE) in terms of a potential function. The PDE is solved as a single series form of the potential function, from which the displacement and force quantities are determined. The solution method applies to cylindrical shells with simply supported edges, clamped edges, free edges, or edges supported by isotropic beams.............

Abstract: This paper presents the testing of a Hybrid Fluid coupling system for effective and efficient Power transmission with fluids having different viscosities at various filling capacities. A specific prototype is designed and built to carry out the performance tests. The objective lies in developing an efficient fluid coupling which would transfer the mechanical power with minimum transmission losses. This fluid coupling would transfer the power from the two main sources, namely the Induction motor or any other source of power and then transmit it to the output shaft through the Fluid medium...........

Abstract: Water access in rural Kenya, and generally in Africa remains low despite the evidence of its importance for livelihood and economic development of all its nations' societies. Sustainability challenges of rural community-managed water supplies leading to high failure rates of up to 60% have been a major deterrent to closing this gap on water access. The aim of this study was to establish the sustainability of water supply cooperatives as suitable alternatives for rural community managed water supplies............

Abstract: Compression testing is most commonly used as quality control measure in concrete masonry production and construction. For checking strength we required smooth surface for uniform load distribution. We use capping material to eliminate surface imperfection and provide uniform load distribution. This project aims to study the strength variation between the capped and uncapped concrete cylinders. The capping material is selected based on the multiple criteria including compressive strength, surface bonding, thickness, Poisson's ratio and hardness. Uncapped cylinders are chosen as control method and are compared against gypsum; cement paste, neoprene pad and steel caps...........

Abstract: Acrylonitrile Butadiene Styrene (ABS) has undergone considerable industrial development because of all of these properties: good heat resistance, high impact resistance, rigidity, and its dimensional stability. The combination of the three monomers which constitute it of chemical and physical different properties, makes it possible to have a material of interest with good performances. The disordered nature of macromolecular chains makes it difficult to understand the mechanisms of deformations and damage on the microscopic scale and the resulting descriptive models are generally............

Abstract: One of the raw materials for making cement is limestone which is a non-renewable natural resource. If limestone is taken continuously then its availability will decrease significantly. Sea shells are one of the marine products in Surabaya. The utilization of sea shells is generally limited to be consumed, while the shell tends to be seldom exploited. The Shells are usually only used as a result of crafts even though shells itself contain compound CaO about 66.7%. This compound is one of the...........

Abstract: Joor Road (La 946) is an Urban 5-lane Portland cement concrete roadway withan annual daily traffic (ADT) of approximately 13,500 with 7 percent trucks and posted speed of 89 kmh. Since being opened to traffic in 2009, residents have been complaining about the high noise levels emanating from the roadway. A comprehensive experiment was developed. The experiment consisted of randomly selecting six Portland cement concrete (PCC) slabs, three north bound and three southbound, in the noisy areas plus an additional slab outside of the noisy area to use as a control............

Abstract: Often in a framed structure, the frames are infilled with stiff construction such as brick or concrete block masonry, primarily to create an enclosure and to provide safety to the users. Such masonry walls are known as Infill walls. The typical multi-storey reinforced concrete framed constructions in India comprise with brick masonry infills. Unreinforced masonry infill wall panels may not contribute towards resisting gravity loads, but contribute significantly, in terms of enhanced stiffness and strength under earthquake (or wind) induced lateral loading. However, in practice..........

Abstract: A three-dimensional study of laminar flow and heat transfer in a channel with built-in oval tube and delta winglets is carried out through the solution of the complete Nervier–Stokes and energy equations using a body-fitted grid and a finite-volume method. The geometrical configuration represents an element of a gas–liquid fin–tube cross-flow heat exchanger. The size of such heat exchangers can be reduced through enhancement of transport coefficients on the air (gas) side............
