The study is aimed at revealing the correlation between the critical coefficient of stress intensity and slag alkaline cement-free concrete structure and strength. Based on the fracture mechanics methods, the comparative assessment of crack formation in concrete of transport structures based on traditional and cement-free slag alkaline binder is performed. The comparison of criteria of crack resistance of high strength slag alkaline concrete and portland-cement concrete has shown that the first one has the stress intensity coefficient 1.5 times higher, fracture energy value 2.4 times higher, a bigger crack size at the same level of loading. Thus, it is concluded that slag alkaline concrete is a perspective and durable material for road and transport structures.
