Abstract: 
Досліджено ефекти дії сульфатів калію на тужавіння цементного тіста. Встановлено, що основні елементи (Ca, Si, Al) розподіляються в складі клінкерних мінералів, тоді як атоми K та S концентруються локально в порах з утворенням водорозчинного арканіту K2SO4. Показано, що взаємодія K2SO4 та CaSO4.2H2O з утворенням сингеніту K2Ca(SO4)2.H2O спричиняє деструктивні явища в цементному тісті.
