Fly-ash has become an important raw material for preparation of sustainable concrete. Several investigations have proved fly ash concrete to be superior than ordinary concrete, in ambient temperature, in terms of strength as well as on durability. Performances of fly ash concrete in different aggressive environment, though, are yet to be investigated. Present experimental study has been made to see the performances of such concrete at fire conditions. A newer approach of mix design of concrete has been adopted here by substituting a part of cement by fly ash weighing twice that of cement, without addition of any chemical admixture. This has made it unique from earlier works done with equal fly ash substitution for cement replaced. The book has been prepared with a brief introduction, brief description of rheology of fly ash concrete, review of literatures available on behavior of concrete at high temperatures, experimental programme, results, discussion along with a concluding remarks. The book will be helpful for the students and researchers working on properties of concrete. As well as it will help graduate students and professionals working with fly ash concrete in construction.

Abstract: While a lot of research has been conducted under on sustainable building materials towards exploring the mechanical and physical properties of fly ash as a recycled material that replaces ordinary portland cement in concrete, little has been directed towards testing its fire resistance properties. Due to the growing need to use fly ash based concrete and the severity of fire, the third most reason for casualties in building inhabitants, this research is directed into exploring the fire resistance properties of fly ash based concrete. After conducting the literature review, the following hypothesis was formulated: not only does fly ash affect the behavior of the concrete, but also other test variables like the oven temperature, the curing period and several others. Therefore, an experimental program was formulated based on the literature findings in order to validate this hypothesis. Four hundred and eighty specimens were prepared to see whether the change in fly ash percentage, oven temperature, coarse aggregate size, curing time, curing method and steel reinforcement affects the fire resistance of concrete. Within the limitations of the experimental testing program, the following main findings can be stated; a) Concrete fire resistance property could be measured by a strength reduction index (Beta) that measures the decrease in compressive strength before and after being exposed to elevated temperatures, b) 30% FA samples has 20-25% higher Beta values than OPC Concrete in the early curing days (3 and 7), c) 30% FA samples has 10% higher Beta values on average in all tested oven temperatures, and d) concrete cured manually has higher Beta values than the ones in the curing room at 200 and 800 degrees.

When used as an addition and binder component, fly ash has become an indispensable construction material for many concrete applications. The conditions produced in power stations when firing fine pulverized coal result in the formation of a reactive, flour-fine, pozzolanic mineral material from the accompanying rock in the coal. Owing to its specific characteristics it has a positive impact on the properties of fresh and hardened concrete and facilitates cost-effective production of high-grade, durable concretes. The authors of this handbook have combined the latest discoveries from the field of research with practical experience of the use and effects of fly ash in concrete. This handbook provides the necessary information and makes interesting suggestions for selective use of fly ash in concrete.
