    ABSTRACT: The preferred management option for coal combustion by-products (CCPs) is utilization as alternative material, rather than disposal as waste. In comparison with fly ash, which presents the ... major share of the total annual CCPs production, the properties of boiler slag are less known. This paper presents the results of laboratory and field investigations of mechanical and environmental properties of boiler slag, produced in boilers, where brown coal is used as fuel. From geotechnical point of view, it is recognized as alternative material for the use as structural fill and for embankments. The leaching behavior was first assessed by means of laboratory leaching and percolation tests. The potential environmental impact, which presents one of the most important limitations for the use of wastes as alternative material, was identified. A test embankment was constructed and a part of it was equipped with a lysimeter. It provides information on leaching trends under field conditions and serves for the long term monitoring of the quality and quantity of percolated water. Based on data obtained from the lysimeter the reliability of laboratory leaching and percolation test results was evaluated.
