road concrete

This article examines the effects of the simultaneous action of sodium chloride and cyclic freezing and thawing on the strength of monolithic road concrete of varying strength classes. There are two methods for protecting concrete and ensuring its durability. Primary concrete protection involves the proper selection of materials and ensuring their optimal ratio. Secondary protection involves treating concrete with special impregnating compounds based on organomineral compounds.

This article presents the results of research crack resistance concrete after exposure to water saturation-drying cycles on the criteria of fracture mechanics. Presented values of power and energy characteristics of crack and deformation diagrams of concrete after water saturation-drying for 100, 180 and 360 cycles.
