摘要：

The self-monitoring behavior of carbon fiber reinforced mortar was found to be affected in two ways by curing age from 7 to 28 days. Firstly, the electrical resistance increased monotonically with increasing compressive strain during first loading at 7 days, but at 14 and 28 days it decreased monotonically. Secondly, the resistance decreased slightly and irreversibly at the end of each cycle as cycling progressed at 14 and 28 days, but not at 7 days. These effects of the curing age are associated respectively with the effects of the curing age on fiber-cement bond strength and on cement compliance. (C) 1997 Elsevier Science Ltd.
