Burlaka A. Increasing of strength and waterproof of horous concrete drainage pipes

The thesis is devoted to experimental and theoretical basis of preparation of porous concrete drainage pipes of high quality hydraulic and urban construction. A theoretical model of the interaction of porous concrete, sand backfill, and water filters. Determined by the configuration of a set of particles for which there is no mudding far. Studied surface area settings macroporous concrete and developed ways to increase its tensile strength using intensive methods of injection molding and microfiller. A method of reducing the cost of materials in the construction of drainage pipe, which in actual standards at the conclusion of clay soils and supesi needs and sprinkled pidsypky layers of sand. A method of providing a flexible and sealed jointing pipes and porous concrete measures to ensure the reduction of the cost of building drainage is developed.
