Sulfoaluminate Type Expansion Agent Based on Industrial Wastes for Concretes
Abstract: This article provides an overview of the existing expansion additives that are manufactured and used to produce concrete with compensated shrinkage. Oxide, aluminate-oxide and sulphoaluminate additives are described. The mechanism of action of each type of additives is outlined. The sulphoaluminate expanding additive is considered in detail, the mechanism of its action in hardening concrete is described. The list of materials of technogenic origin for aluminate and sulphate components, as well as an active mineral component, are most suitable for creating additives of this quality in the regional conditions of the Donbas.
Keywords: shrinkage, expanding additives, oxide type, aluminate-oxide type, sulfoaluminate type, spent catalyst, slags of metallurgy, cenospheres, burnt rocks of mine waste banks.
