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 …

Nano based Phase Change Materials for Thermal Storage Applications: A Review
Abstract: Conventional thermal energy storage systems have low energy storage densities and are incapable of undergoing isothermal storage process. Phase Change Materials (PCMs) are gaining attention as potential materials for thermal energy storage from intermittent renewable energy sources. Latent heat storage materials (LHS) called PCMs can release or absorb heat energy when a change in physical state occurs. Although PCMs have high energy storage density, their poor thermal conductivity remains a …

Physico-mechanical, and Biodegradation Properties of Polyethylene/Food Polysaccharide Blends
Abstract: Hydrophilic/polar and hydrophobic/non-polar materials do not blend well, which causes issues in the production of biodegradable plastic. Plasticizer (glycerol) was one of the components added to the mixture to increase compatibility between the two materials; this also made the film less brittle. The purpose of this study is to look at how different food polysaccharide contents affect the physico-mechanical, and biodegradation characteristics of novel polymeric-based bio-composite films made from low-density …

Fabrication and characterization of Aluminum-Granite-Graphite Metal Matrix Composite
Abstract: Moving machine elements are constantly subjected to wear and tear. Machine life can be improved by using hard and wear resistant materials. Most of machine elements are made of metals or alloys. These materials alone cannot meet the requirements of design of long-life machines. Naturally occurring hard materials lack the strength to withstand the machine loads. Composite materials provide the solution to such requirements. Based on requirement, a composite material …

Effect of Coupling Agent on Organoclay Dispersion in Polyethylene/Organoclay Nanocomposites for Packaging Industry
Abstract: Low-density polyethylene (LDPE) is one of the most widely used polymers in various fields, but due to the hydrophobic nature of LDPE, it is hard to prepare an LDPE/clay nanocomposite. In this article, an LDPE/organoclay nanocomposite, which can be used in the packaging industry, was prepared by melt-blending organoclay with a polymer matrix (LDPE) and compatibilizer, low molecular weight oxidized polyethylene. The influences of organoclay, and compatibilizer during melt mixing …

Predictive Model on Constant Pressure Drop Variable: Area Fluid Flow System in a Pipe
Abstract: The effect of density, pressure drop, and orifice area was examined in this research. The basic equation developed to represent steady-state fluid flow is the Bernoulli equation which assumes that the total mechanical energy is conserved for steady incompressible, in viscid, isotherm flow with no heat transfer or work done. These restrictive conditions can actually be representative of many physical systems. The Bernoulli’s principle was applied in explaining the design …
