The paper describes the characteristics of belite sludge - a large-tonnage waste of alumina production. The influence of negative temperatures on the technological properties of the sludge was investigated. The regularities of sludge cooling during its excavation, long-term storage and in the technological process of structural layers’ construction in winter conditions have been studied. Recommendations have been developed for the construction of foundations (coatings) from sludge and sludge-mineral materials at temperatures below minus 20°C. The implementation of research results helps to prolong the construction season, reduce material consumption and increase durability during construction, reconstruction and repair of transport infrastructure objects.
