Reduction of negative impact on the geoenvironment using silica sol in road construction

Abstract

Consumption and pollution of natural resources must be constantly compensated by their conservation, saving and restoration to create a balance in the ecosystem between man and nature. To solve this problem any construction process must be accompanied by geoecoprotective measures. The authors of the article suggest to use silica sol in the soils stabilization and reinforcement technology. Silica sol is a pure mineral product that has binding properties and neutralizing properties against some pollutants. This makes it suitable for soils reinforcement and also soils neutralization from pollutants such as heavy metals ions. The stabilization technology using technogenic soils and silica sol will conserve natural resources, improves the soil strength properties and neutralize them from pollutants.
