Abstract:

Low permeability to water is a primary consideration in the design and construction of earth-covered concrete structures. Factors affecting the permeability of concrete are generally classified into three groups 1 constituent materials 2 methods of concrete preparation and 3 subsequent treatment of the concrete. Each group of factors is examined in this paper and recommendations are made on how to obtain concrete that is virtually impermeable. Also, some specialized concretes with potential applications in earth-covered structures are discussed briefly. These include polymer-impregnated, polymer, and fiber-reinforced concretes and ferro-cement. Author
