Plugin A. The durability of a concrete and reinforced concrete of a water-contently structures: the colloid-chemistry basis

The durability of a concrete and reinforced concrete of the large structures, in particular tunnels, bridges, sewage collectors, reservoirs et al, exploited in the conditions of flooding and bend, far below, than exploited in normal circumstances. The existent notions of durability and concrete for such construc-tions are unaccomplished. In dissertation the quantitative theory of durability of flooding concrete, reinforced concrete and stone constructions and building are developed. The feature of this quantitative theory consists that in it are used ideas of colloid chemistry, physic-mechanics of the dispersion systems and materials and basic positions about electroheterogenеous interaction at hardening cement bindings. On the basis of these ideas and positions new notions of machineries of elementary processes of forming of strength, destruction, deformable, waterpermeability, corrosive resistance, crack resistance and on the whole durability of cement stone, mortar and concrete and flooding constructions from them are given. The proper physic-mathematical models allowing to forecast durability of the indicated flooding constructions are developed. The developed new theoretical notions of durability of flooding constructions allowed to create the complex of high effective a methods of research of their technical state, and also complex of new materi-als, products and technologies for their renewal, strengthening, sealing and extension of durability, which is effectively used on many real constructions and building.
