| Abstract: | The stress-resistance relationship of carbon fiber cement was studied.Attention has been paid to explore the improvement of the stress-resistance sensitivity under cycled stress restriction.The prismy carbon fiber cement sensors were pre-fabricated.The factors such as contents of carbon fibers.silica fume,dispersant and the w/c were taken into account.The electrical resistance variations with the dynamic and static loads were simulated using a strain-controlled test machine.The test results show that there is an optimal fiber content,with which the compression-sensitivity achieves a high level.The addition of silica fume can improve the sensitivity.Under the optimal test conditions,the measured resistances can greatly correspond with the changes of the load. |
