Some ageing characteristics of lime

摘要: This study involves the special case of lime compacts which are considered to serve as models for system in hydrated Portland cement paste. The ageing was studied by measuring length changes powdered samples under various steady-state and alternating conditions humidity. As an explanation unique behaviour compacts, a primary mechanism is proposed based on theory that recrystallisation occurs at least areas particle contact when exposed humidities above certain value. Furthermore, this recrystallised product more accommodating than parent material, hence it can be consolidated forces due menisci or surface free-energy. action manifested irreversible shrinkage storage intermediate humidities, drying after between two levels
