Soil Reinforcement and Detoxication by Means of Mineral Binder Systems

In the paper the problem of pollution of the railway ballast by heavy metals is considered. Heavy metals migrate into the soil under the action of precipitation and acid rain. Environmental pollution caused by heavy metal ions is particularly hazardous. Unlike other pollutants in soils the heavy metal ions reserve for a long time even after removal of the pollution source. The ability of heavy metal ions to migrate to soil, into the underground, ground and surface water, to accumulate in food leads to the need of consideration of their impact on human health. Heavy metals are carcinogenic. To solve this ecological problem we offer to reinforce contaminated ballast by means of binder systems having geoecoprotective properties against heavy metal ions.
