Sažetak
The number of studies on the possible utilization of waste materials or industrial by-products from certain building technologies is continuously increasing, although it started many years ago. There are numerous reasons for this. One aspect is to rationalize consumption of good quality natural resources and the other is to minimize large disposal of waste material and industrial by-products. Out of a wide range of alternative materials used in road construction, a special place is given to fly ash. An advantage of this product is that it can be used in its original form, without any reprocessing or content change. The benefits of this material, the fact that it is primarily waste material with changeable content should be considered. The decision to utilize fly ash should be based on the evaluation of possible impacts on soil and underground water. Namely, properties of fly ash depend on the type of coal used in power plants, this reflecting on the chemical and mineral characteristics of ash as well as metal concentration. This paper describes the present understanding of fly ash impact on the environment, emphasizing Croatian research and application experience.
