| Abstract: | To solve the problems that cracking location of traditional ring test is random and cracking sensitivity of the test is bad,outside-square inside-circle eccentric constraint method is proposed.The cracking test of cement paste and mortar are done using the method.Experimental results show that the method can predict the cracking location of specimen,which makes easier for cracking observation,and cracking sensitivity of the method is good,so the method can accelerate the cracking of specimen and shorten test cycle. |
