The Principal Component Analysis about Optimal Ratio for High Performance Pavement Concrete

Abstract:

The high performance cement concrete mixture design for pavement was studied through a series of laboratory experiments based on an actual project program. We analyzed the data by principal component analysis and tested the concrete performance of strength, shrink and freeze-resistance. The results of a series of experiments indicated that the dry-shrink rate was reduced obviously by using expanding agent. The flexural elastic modulus increased as the flexural strength increasing. Adding air-entraining agent could improve the air content of the concrete, and as a result, the flexural elastic modulus was reduced and freeze-resistance performance was enhanced greatly.
