This document summarizes research on the relationship between asphalt mixture material characteristics and highway noise. A tire-pavement noise simulator was used to measure sound pressure levels of various asphalt mixtures in the laboratory. Multivariate regression analysis found the best predictive model for sound pressure level includes variables for complex modulus, voids filled with asphalt, copper content, and lead content. Testing was performed on different mix designs, including superpave, open graded friction course, and stone matrix asphalt containing various modifiers. Correlations were explored between sound pressure level and material properties.

Compatibility study of slag cement with PCE based admixturesAbdulRazakBH
Abstract - Admixture-Cement interaction in concrete is a complex blend of chemical and physical mechanism that are independent. Every admixture at optimum dosage gives better results when used with cement. The proposed research work is aimed at testing compatibility of slag cement at different dosages with PCE based admixtures. It was found that The Combination 80% Cement With 20% GGBS Are More Compatible Compared To All The Optimum Dosage Combinations.

Numerical modeling and experimental evaluation of drying shrinkage of concret...Mohamed Moafak
In order to handle complex nonlinear relationships between various inputs and outputs, soft computing techniques are used. The aim of the study is to derive mathematical models obtained from neural network and genetic programming. For this, experimental data were utilized from the available test results presented in the previous studies. The prediction parameters were selected from mixture constituents of concrete and drying period.
Second stage of the thesis is to evaluate the model by experimental validation
Investigation of Significant Process Parameter in Manganese Phosphating of Pi...IJERA Editor
The aim of this study is to determine the most significant parameter such as phosphating bath temperature,
phosphating time,accelerator level on the fatigue life of piston pin material such as 40NiCr4Mo3 by analysis of
variance (ANOVA).The selected three imput parameters were studied at three different level by conducting nine
experiments based on L9 orthogonal array of Taguchi’s methodology.Phosphating bath temperature has
significant effect on fatigue strength followed by phosphating time and accelerator level.

Diffuser in Steam Vent Silencer By Using Computational Fluid DynamicsIJERA Editor
Recently, research on new techniques for noise reduction of steam vent silencer has been addressed. However,
research work on shape optimization of steam vent silencer along with work on pressure drop has been sorely
neglected. Therefore, a numerical simulation has been investigated on the pressure drop using steam vent
silencer is introduced in this research work. This emphasizes the variation of pressure drop with the influence of
holes with various geometries like circular holes, square holes and square extrusion in pressurized inlet diffuser.
The sensitivity of pressure drop is less in square extrusion, compared to all other geometry. So it can conclude
that shape optimization of pressurized inlet diffuser in steam vent silencer is obtained with the application of
square extrusion.
Experimental Study on the Properties of Rice Husk Ash with A.A.A Portland Cementijtsrd
In the last decades, the use of residue in civil construction, especially in addition to concrete, has been subject of many researches due to reduce the environmental pollution factors, it may lead several improvements of the concrete properties. Myanmar is one of the largest rice producing countries and per capita rice consumption is higher than that in any other countries. Considering that 20 of the grain is husk, and 20 of the husk after combustion is converted into ash. In this study, the chemical composition and physical properties of A.A.A Portland cement are tested. The rice husk ash RHA is obtained from Shwebo. And then, the ingredients of mortar and concrete such as sand and aggregate are tested. In this study, Ayeyarwaddy rivers sand is used. According to the silica content, the replacement percentage of RHA is considered as 0 , 5 , 10 , 15 and 20 by weight of cement. Finally, the compressive and tensile strength of mortar, and compressive strength of concrete are tested with various percentages of RHA. The results were compared to control sample and the viability of adding RHA to concrete is verified.
