Absorptive Properties of Hydrate Silicate Building Materials and Products for Quality and Geoecoprotection Improvement


Background: Two directions of absorption of silica sol usage for construction are shown. The first direction is the usage of silica sol by means of absorption silica sol solution process and the second is obtaining silica sol according to reaction between clay mineral (Al2O3•4SiO2•2H2O) and H3PO4 solution. Methods: Thermodynamically-based method of research is used to study silica soil properties. In addition, experiments were held to illustrate quality and geoprotection improvement due to absorptive properties of hydrate silicate building materials and products. Findings: First, processes can improve the technical properties of the concrete and, second, can strengthen and detoxicate soil (ground) at the same time. The possibility of silica sol absorption by means of capillary porosity of concrete structure and the change of technical properties of absorbed concrete have been shown. Sand and clayish soil strengthening and detoxication by means of silica soil saturation and obtaining silica soil during the reaction have being revealed as well. The reactions between clay and phosphoric acid have productive silica sol. If there are heavy metal ions in the soil, so it is possible to obtain phosphates and silicates with very low solubility product. Silica sol formation in the soil is very important for lithosphere detoxication not only from heavy metal ions but from oil pollutions as well. Improvements: Such a way is possible due to artificial stone formation to improve technical properties of concrete and to prevent lithosphere toxication.
