This book draws together a large quantity of research that has been carried out on pulverised fuel ash (PFA) over the past 30 years. Fuel ash and fly ash are produced as waste from burining coal (or waste materials) and have many uses within the construction industry such as in concrete land reclamation, treating oil and sewage wastes, bricks and blocks and grouting voids in the ground. In addition to covering the potential uses of PFA it provides an overview of the benefits of use.
