Scope of Application
According to the Construction Rules
Application according to recommendations of Concrete and Reinforced Concrete Research Institute It is especially effective in the construction of foundations and monolithic works, as well as in road construction for products working on an elastic foundation (foundations and slopes of roads, asphalt concrete pavement, retaining walls, slabs, etc.). It is promising for creating earthquake-resistant zones of buildings and structures both existing and newly erected.
