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 finish ....etc

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 compositio ....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 dat ....etc

Introduction
Cement-treated or cement-stabilized soils have been used in pavement
base, subbase, and subgrade construction since 1915 because
cement has been effective in improving the engineering
properties of a wide variety of soils, including granular materials,
silts, and clays
PCA 1992. Usually, cement-treated soils are
mixed with low cement dosages with or without a targeted
strength, depending on their functions, whereas the cementstabilized
soils are mixed with high cement dosages with a targeted
