Abstract
Experimental studies are devoted to the problem of the resistance of magnesia binders to the effects of aggressive liquid mediums. The object of the study is caustic magnesite and mixed binders containing technogenic components. Cements of various compositions were used for comparison. The conditions for testing binders provided for the use of high-concentration salt solutions and alternating changes in the hardening medium. The research results indicate the influence of the technogenic component on the structural changes of binders under the influence of water and salt solutions. Increased resistance of magnesia-slag binder in saline solutions has been established. The tendency of stabilization and hardening of binders after prolonged exposure to liquid mediums has been revealed. The research results expand the understanding of the properties and applications of magnesia binders
