Abstract
The main trend in the development of the production of building materials in the XXI century is associated with the use of man-made raw materials as sources. In this work, the applicability of technogenic raw materials in concrete technology has been investigated. Two types of hydraulic concrete with fly ash additives have been developed on a large traditional aggregate and a fine-grained aggregate from an ash-and-slag mixture.The results of tests of hydraulic concrete for monolithic construction - concrete shaft support using ash and slag waste are presented. The results of laboratory studies were confirmed by positive production tests during monolithic concreting of an experimental run-in of a ventilation shaft. The use of ash and slag waste in hydraulic concrete allowed saving 30% of cement and 100% of crushed stone and sand.
Keywords
