摘要：It is shown in the paper that various secondary technogenic products and industrial wastes are effectively used as cheap raw materials for the production of road construction material. The hardening kinetics of the nepheline-sand mixture compacted at different initial humidity was studied, which showed that when nepheline sludge used as a binder, a relatively uniform set of strength of the samples was observed for a long time. Analysis of the aqueous extract from nepheline sludge showed there are ions of Ca++, K+, Na+, CO3 2−, HCO3 −, SO4 2−, Cl− in it. Using the method of biotesting confirmed the absence of toxic effects of the proposed technogenic materials for use in the strengthening soil of road pavement.
