The project aims in the utilization of fly ash in concrete with addition of mineral admixture, aiming for the improvement of the different characteristics of concrete and in order to increase the concrete performances and to maximize the economic and environmental benefits. The main objectives of this paper is to utilize fly ash concrete with mineral admixture, investigating the possibility of increasing the performance of concrete and improve the cohesiveness and workability of the concrete, resulting in the reduction of thermal cracking and maximizing the environmental and economical benefits. In this study different tests will be carried out such as, slump test, compression test and carbonation test to test the character of the concrete mixed with fly ash and admixture.
The Project is about an Experimental study on the utilization of fly ash in concrete with mineral admixture, aiming for the improvement of different types of concrete and to increase the concrete performances and to maximize the economic and environmental benefits.
History of fly ash
The use of Fly Ash in concrete was first carried out by Davis and his associates in University of California in 19374. Though extensive research was carried out throughout the world to encourage the use of Fly Ash in construction industry, only a few milestones could be accomplished till 1960 and that too in industrialized countries only. As far as Oman is concerned, the first ever study on use of fly ash in concrete was carried out in 1955 by CBRI, Roorkee5, in the form of a review of American and Australian research work on Fly ash. Later, Fly ash was used in small proportions in mass concreting for dams and other hydraulic structures.
The methodology used in this project is an experimental based study where the tests carried out are:
Slump Test: for the means of checking that the correct amount of water has been added to the mix which basically means...
