IMPROVEMENT OF CONCRETE DURABILITY BY COMPLEX MINERAL SUPER-FINE POWDER



Introduction
Coal gangue is a rock included in the coal bed and a waste discharged during coal
mining and transportation as well as the most industrial waste discharged in China. It
is estimated , that the amount of gangue calculated as 15% of the coal output,
there would be 100 million ton increment annually. Most of the coal gangue is a clay
rock; its main mineral composition consists of clay min ....etc

IMPROVEMENT OF MECHANICAL PROPERTIES OF RIGID PAVEMENTS

INTRODUCTION
Transportation-basic infrastructure-development

Rigid and flexible

Basic neccesity-stable against loads

Rigid offers more strength load

But change in temp. warping up and warping down

To relieve stress-joint

Joint from the weaker plane and most of defects occur there

Increase the mechanical properties such as load carrying capacity and cracking resistance

Methods for improvement


Rigid Pavement
Consist of sub ....etc

STUDY ON DURABILITY OF FLYASH CONCRETE



INTRODUCTION

Fly ash is a byproduct of coal burning power plants - the ash that flies up their
smokestacks and gets captured in giant filters. It can be used to produce stronger, more
durable and more environmentally friendly concrete. When used in concrete, fly ash acts like
cement, and actually replaces a percentage of the Portland cement normally used. Concrete
with high percentages of fly ash looks and finishes the same as regular c ....etc

Abstract
This study aims to determine the influence of the content of water and cement, water binder ratio, and
the replacement of fly ash and silica fume on the durability of high performance concrete (HPC) by using
artificial neural networks (ANNs). To achieve this, an ANNs model is developed to predict the durability of
high performance concrete which is expressed in terms of chloride ions permeability in accordance with
ASTM C1202-97 or AASHTO T277. The model is developed, trained and tested by using 86 data ....etc

ABSTRACT

The dictionary has many definitions for quality. A short definition, that is widely accepted is Quality is customer satisfaction. Quality is a relative term generally used with reference to the end use of the product. According to Edward Deming Quality should aim at customer need both present and future. The increasing need for quality resulted in formation of quality management systems (QMS) .When international organizations of standards (ISO) which comprises of National standard bodies of 95 countries put forward some qua ....etc

Abstract::
The demand for wireless mobile communications services is growing at an explosive rate, with the anticipation that communication to a mobile device anywhere on the globe at all times will be available in the near future.
An array of antennas mounted on vehicles, ships, aircraft, satellites, and base stations is expected to play an important role in fulfilling the increased demand of channel requirement for these services, as well as for the realization of the dream that a portable commun ....etc
