Information Assessment of Natural Geosystem Preservation in Geoconstruction by Improving the Quality of Concrete

The research area is natural geosystem preservation during the geoconstruction operations. The problem is connected with the cold region because of low temperature influence on the quality of the geoconstruction. The aim of the research is: firstly, by improving concrete properties, to improve the quality of concrete articles in geoconstruction, their durability and, therefore, to reduce the consumption of natural substances; secondly, to assess the achieved quality by introducing a new summative assessment called quality index. The methods of the research are physical-mechanical and experimental ones for evaluation of the concrete properties, and rating method of quality assessment which has been developed and presented to testing. The improvement of concrete properties was achieved by using sol adsorption technology. By using quality index, the quality assessment showed 37% increase. The achieved results make it possible to reduce the consumption of natural sand and, consequently, preserve natural geosystems in geoconstruction.
