The article shows the comparative analysis of two compositions of cement concrete to use in road construction. In order to compare quality characteristics of the materials the method of Y.M. Butt was used that was implemented to test Portland cement samples made at Magnitogorsk cement refractory plant and cement rock on the basis of lime slag binding agent that was developed based on blast-furnace granulated slag together with Magnitogorsk Metallurguc Plant, PJSC. Computational and full-scale experiments were conducted to forecast the time changes of qualitative parameters of road surfaces with slag. It was established that its endurance to the first and second type of corrosion is higher. It was proved that lime slag concrete can be used in the production of road fine grain concrete instead of Portland cement, the presented binding agent also proved to be more economically feasible.
