摘要：This paper studied the piezoresistive effects of cementitious composites filled with nano graphite platelets (NGPs). Experiments are performed to investigate the electrical responses of cementitious composites filled with NGPs when subjected to cyclic compressive stress under different quasi static and dynamic loading conditions such as different loading amplitudes, different loading rates and constant loading within the elastic regime of these composites. Meanwhile, the cementitious composites filled with NGPs are explored for the application in measuring dynamical loading rate. The results demonstrated that cementitious composites filled with NGPs possess sensitive piezoresistive effect and stable repeatability to different loading conditions. (C) 2017 Elsevier Ltd.
