Abstract: On the basis of the theory of grey connection analysis, the correlation between the qualities and crack resistance of cement is experimentally studied. The results show that the content of C2S, which affects the crack resistance of cement maximally, has a positive interconnection with the crack resistance of cement, and the content of C3S has a negative interconnection. The sequence of factors that affect the cracking time of cement paste is C2S content>specific surface area >C3A content>C3S content>C4AF content.

Key words: grey connection analysis ,  quality ,   crack resistance
