Description
Summary:The article evaluates the possibility of using organic-mineral aggregate for strengthening sandy subsoil. As an organic component of the organic-mineral aggregate, glyoxal is used. To ensure uniform polymerization throughout the required thickness of the sandy subsoil a mineral component was admixed into the aggregate. The above component is saponite containing pulp waste produced in the industrial ore benefication tailing dump of the diamond deposit named after M.V. Lomonosov. It was found that glyoxal is a surface-active substance. The tailored content of glyoxal was identified by the OWRK method (Owens–Wendt–Rabel–Kaelble). In the paper the results of research on the strength properties of sandy subsoil modified by the organic-mineral aggregate are presented. It is shown that the tailored aggregate content allows increasing the specific cohesion of sandy subsoil by up to 50 times.
