Influence of GGBFS on the Mechanical Properties of the Water Cured Fly Ash Aggregate-Based Geopolymer Concrete
Abstract: Abstract Conventional concrete consists of cement, sand as fine aggregate and gravel, limestone or granite in various sizes and shapes as coarse aggregate including with water. In the present work, the feasibility of using industrial inorganic polymeric residues wastes as a total (100%) replacement to the traditionally used normal conventional concrete materials is examined in the preparation of the geopolymer concrete (GPC). In this GPC, the cement is totally replaced …

Re-Characterization of Strength Properties of Asphalt Concrete Mixtures Using Non Bituminous Modifier – Candle Wax
Abstract: Improving the performance of asphalt concrete mixtures synonymous with flexible pavement has been a major concern in highway engineering. However, design of flexible pavement begins with proper material characterization to ensure that designs are appropriate. It is also pertinent to say that sometimes if not most times the properties of the individual materials that make up the pavement structure falls short of desired expectations. This has led to exploring techniques …

Review Study on re-strengthening of reinforced concrete circular column using steel strips
Abstract: This technique fixes thin steel plates i.e. steel encasement or tie plates i.e. steel cage around the column with steel angles at each corner, clamped to the concrete and welded together. Adequate tightening of the jackets can be ensured by means of heat tensioning. The use of steel jackets can enhance the shear strength of columns considerably. However, due to their low flexural stiffness they typically have poor confinement efficiency …

A parametric study for the behaviour of steel plate-anchor assembly embedded in concrete under cyclic loading
Abstract: Steel plate-anchor assembly embedded in concrete is a common type of connection system used for connecting structural steel members to concrete members. These assemblies are subjected to different loading cases depending on their use. Since the behaviour of such assemblies is quite complex and depends on a number of factors associated with different components, it was decided to adopt finite-element technique to obtain a reasonably accurate analytical solution for the …

Object Reconstruction Using Phone and Compact Camera
Abstract: Previously, a 3D model can be produced by using high resolution and metric camera in close range photogrammetry technique. In this study, there were two types of camera used; the compact camera (Nikon COOLPIX L120) and phone camera (Samsung Galaxy Note1). Two objects were selected; i.e., a biscuit container as for simulation and water tank as the real object. 3D models for both objects were validated by using a measuring …

Composting of Municipal Solid Waste to Enhance the Fertility of Soil
Abstract: Composting has been used as a method of utilisation organic matter into the soil to boost soil structure and fertility. The composting method has received abundant attention in recent years due to pollution issues and also the seek for environmentally sound strategies for treating waste. Waste volumes still rise, that ends up in loss of resources and inflated environmental risks. Open selling and landfill could be a major technique for …

Predicting the Influence of Permeability’s on Settlement of Shallow Foundation
Abstract: Foundation settlement rose as soil permeability increased, excess pore pressure increased with depth, and decreased as shear modulus increased. The expanding soil cycle (shrinkage and expansion) that is principally responsible for foundation settlement is strongly related to water content. The application of modeling and simulation was used to monitor the effect of various soil properties on foundation settlement. But the focus of this study is on Permeability including other soil …

FINITE ELEMENT ANALYSIS OF BI ANGLE SHAPED SQUARE FOOTING UNDER TWO WAY ECCENTRIC LOADING
Abstract: Footing subjected to eccentric loading along two mutually perpendicular axes is quite a common field problem. Due to this bearing capacity is reduced considerably as the effective size is drastically reduced. A footing may be subjected to two-way eccentricity due to many reasons. In the case of footing subjected to one-way eccentricity the common practice is to match the centre of gravity of column loads to centre of gravity of …
