Influences of temperature and opening rate of substrate cracks on the mechanical behaviour, crack–bridging ability and deformation mechanisms of one–component, cementitious, flexible waterproofing membranes

摘要: Abstract One–component, cementitious, flexible waterproofing membranes bridge cracks because their polymer-dominated matrix takes up the deformation. The sensitivity of deformation polymers to temperature and strain rate raises interest influence these two parameters on crack–bridging ability membranes. Temperature–controlled dog-bone experiments with in–situ monitoring sample's surfaces show a decrease in (CBA) plastic at testing temperatures above glass transition (Tg) used polymer. At below Tg, deform brittle manner. Rate–controlled tests reveal decreasing displacement rate. Hence, are crucial governing crack-bridging performance
