The cements contain, apart from Portland clinker, other non-clinker mineral components, mainly industrial refuse. The source of chemical pollution of the cement binders may originate from materials and substitute fuel (e.g. industrial and domestic refuse).The main goal of the research project was evaluating the influence of cement-ground road foundations on the roadside ecotone zones in the fresh mixed broad-leaved forest. The research focused on five types of cements, which contained different percentage of fly ashes and furnace slag. The process of chemical compounds leaching from cement-ground mixtures was described at two levels i.e. laboratory tests and field investigations. The reaction of both sand eluates and hardened cement-ground mixtures was analyzed to describe the influence of cement-ground mixtures on forming the reaction of ecotone zones soils. Additionally, the reactions of duff and soil samples taken at three depths were described. Trees assimilatory organs, as well as ground cover were also monitored. Samples of soils for chemical and bio-indication investigations were collected from two transects, parallel to the axis of each of the five experimental sections, as well as the experimental one. It was found out on the basis of the carried out experiments that the reaction of the eluates of all ...
