Konnov M. Modified Bituminous Emulsive Pastes and Mastics for Water Proofing of Reinforce-Concrete Structures

The dissertation is devoted to the development of formulations and technology of production of energy saving modified bitumen emulsion paste and mastics for fabrication of durable hydro proofing layers on the surface of concrete and reinforced concrete structures on the base of determination of structure formation and properties of bitumenpolymer and sulphuric emulsion mastics. The dissertation is devoted to the theoretical study and experimental verification of the composition and to the development of the production technology of modified bituminous emulsive pastes which comprise a bitumen-polymer-sulphur binding - 42-52% (bitumen BND - 40/60 measure units (m.u.), butadiene-methyl-styrene rubber SKMS - 30-2 m.u. and industrial sulphur - 40 m.u. above 100 m.u. of bitumen); slaked lime - 15-17%; chrysotile-asbestos of the 7th grade - 7-9%; water - 25-27% and bitumen-polymer-sulphur emulsive paste - 84-86%, grounded riddlings of waste open-hearth slag of the specific surface 350-400 meters square/kg - 14-16%, and addition of water above 100% to provide mobility which is characterized on the cone of the Building CNDL 12-14 cm. There have been determined physical and deformation characteristics of the stabilized bitumen-polymer-sulphur emulsive paste of the optimal compositions and it has been found out that because of some properties they are higher than the parameters of bitumen-emulsive mastic quality which are given in the State Standard B.V.7.108.2001 "Roof and Ware Proofing Mastics. General Specifications". For the Public Company "Donbasrembud" (Repair of Buildings in the Donbas) there heve been developed "Recommendations for Producing and Using Modified Bituminous Emulsive Pastes and Mastics".
