Draining cement concrete for hydrotechnical, road and airport сonstruction

Abstract

The article is devoted to the selection of the composition of the cement-concrete mixture and the determination of physical and mechanical parameters of the draining cement concrete for the arrangement of the pavement of footpaths, parking lots and hydraulic structures with high drainage capacity. The object of research is the processes of composition design and ensuring the strength and capacity of draining cement concrete. The aim of the work is to select the composition and determine the physical and mechanical (compressive strength, tensile bending, deformable (modulus of elasticity), operational (abrasion), frost resistance, water permeability of draining cement concrete. Research methods - scientific and experimental. The results of the article can be used in the operation of road and airfield pavements in the culverts and foundations to improve the environmental friendliness of cities.
