Useless waste materials are often stored in urban areas taking valuable land and polluting the environment. There has been undertaken research which aim was to test the applicability of the ashes from multi-year heaps as a partial substitute for sand. In the ash-cement composites 10%, 20% and 30% weight of sand was replaced by an ash. Composites sand-ash-cement was modified by an addition of hydrated lime. Introduction of new materials environmentally friendly, using industrial waste is desirable when by using waste materials there is a possibility to obtain materials with desired, assumed technical characteristics and durability. The 30-day trials were subjected to corrosion in 6% solution of sodium chloride and magnesium sulfate. After the corrosion designated the compressive strength of each series, which compared with strengths of series in the same age and not subjected to corrosion. Generally, all composites with the ashes scored higher compressive strength in the control series - without ash. The presence of ash in composites significantly reduced the effects of corrosion. These results suggest the possibility of using these composites in road construction.
