The purpose of work - researches of a contact zone " a cement stone - a alkaline-unstable filler " composition materials and their physic mechanical characteristics, including what influence durability of a material, for an establishment of interrelation between processes of structurization in a contact zone and durability of a material. Methods of researches - physic mechanical (durability at compression and a bend, own deformations of усадки/expansion, frost resistance, atmospheric resist, corrosive stability, density, porosity, filtration ability), physical and chemical (researches of a microstructure of a contact zone " a cement stone - a alkaline-unstable filler " with the help of an electronic microscope). As a result of the executed work long-term research of a contact zone " a cement stone - a alkaline -unstable filler " is continued on the basis of traditional портландцемента, slag-alkaline binders and alkaline портландцемента with the help of an electronic microscope. Influence such as a filler, such as binder, such as the additive, conditions of storage (temperature, humidity) on durability of compositions is determined at a bend and compression. Own deformations of усадки/expansion of samples, as exponent of course коррозийных processes in a contact zone are investigated. The interrelation between processes of structurization in a contact zone and durability of a material is established. Purpose(assignment) and area of use of development - improvement of physic mechanical and operational characteristics, increase of durability and reliability of compositions on the basis of alkaline -unstable fillers and mineral alkaline binders.
