Micro-cantilever testing on the short-term creep behaviour of cement paste at micro-scale

摘要: Abstract This study proposes an experimental method for studying the short-term creep behaviour of cement paste at micro-scale. The micro-bending tests on miniaturized cantilever beams were used to characterize viscoelastic properties paste. effects w/b ratio, type binder and stress level microscopic investigated. It is found that microscale can be satisfactorily described by a power-law function. A linear has been observed in different cementitious systems with up 67.9%. When compared results microindentation conventional macroscopic tests, obtained compliance function this both qualitatively quantitatively representative results. underlines importance microstructural effect behaviours materials microscale.
