Regions with a developed metallurgical industry, whose waste in the form of slag dumps are a source of environmental pollution. One of the directions of utilization of slag dumps is the use of slag for road paving. In the article the issues of application of low-maroon binder on the basis of steel-smelting slag for strengthening the bases of highways are considered. Chemically stabilized Al2(SO4)3.18H2O was used as a β-C2S activator to create reactive minerals in the slag. Сalcium hydrosulfoaluminate formed in the hardening system acts as a crystal seed for crystallization of calcium hydrosilicates. The effect of the amount of activator-additive Al2(SO4)3.18H2O on the strength of slag binder-based samples was studied. As a result of the study conducted the optimum dosage of activator making it possible to obtain the highest physical and mechanical characteristics of samples based on slag-mineral mixtures has been established.
