Abstract. The article considers the problem of the useful use of manmade sands. It has been shown that the silicate component of such wastes allows them to be used in strengthening soils to increase load capacity, for example, in the construction of railways and highways. When implementing the technological solution of soil strengthening, it is proposed to introduce a highly movable foam mixture into the earthen web by injection, in which part of the natural sand is replaced with man-made sand. The article provides data on the strength of cement runts obtained using man-made sand.
Key words: silicate-containing wastes, manmade sand, cement runt.
