Silica fume is a processing waste of ferroalloy factories. The application of silica fume instead of cement allows producing high strength concrete, as well as concrete types of the middle and low classes providing a saving in cement of up to 50 %. The authors have developed a technology for preparing a concrete mixture for reinforced concrete structures with silica fume. The technology is simple and does not require additional expensive equipment having low power intensity. The technological parameters have been investigated. They are related to slump, maturing conditions during steam curing and monolithic casting. The economic efficiency of applying concrete mixtures containing silica fume has been determined.
