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

replacement of cement with red mud and replacement of fine aggregate with quarry dust

ABSTRACT

The Bayer Process for the production of alumina from Bauxite ore is characterized by low energy efficiency and it results in the production of significant amounts of dust-like, high alkalinity bauxite residues known as red mud. Currently red mud is produced almost at equal mass ratio to metallurgical alumina and is disposed into sealed or unsealed artificial impoundments (landfills), leading to important environmental issues. It comprises of oxides ....etc

Abstract

This study presents an experimental study on self-compacting concrete (SCC) with two cement content. The work involves three types of mixes, the first consisted of different percentages of fly ash (FA), the second uses different percentages of silica fume (SF), and the third uses a mixture of FA and SF. After each mix preparation, nine cylinder specimens are cast and cured. Three specimens are cured in water for 28 days, three specimens are cured in water for 7 days, and three specimens are left in air for 28 days. The slump and V-fun ....etc

partial replacement of cement with egg shell powder literature

Abstract

This paper reports the results of experiments evaluating the use of egg shell powder from egg production industry as partial replacement for ordinary Portland cement in cement mortar. The chemical composition of the egg shell powder and com-pressive strength of the cement mortar was determined. The ce-ment mortar of mix proportion 1:3 in which cement is partially replaced with egg shell powder as 5%, 10%, 15%, 20%, 25%, 30% by weight of cement. The compressive strength wa ....etc
