✦ Synopsis

This investigation examined variables influencing the 28-day compressive strength and 50-cycle salt scaling loss of concretes made with eighteen Type 10 cements. Statistical analysis was performed on test data consisting of chemical and physical properties of cements; properties of fresh concretes; compressive strength, sak scaling loss, and air void parameters of mature concretes. For a similar water-cement ratio and cement content, results from the correlation analysis indicated that the 28-day concrete strength and 50-cycle salt scaling loss were influenced significantly by the chemical and physical properties of the cement used in the mix. The variables identified in the correlation analysis were analyzed and equations predicting strength and salt scaling loss of concrete were developed using multiple linear regression.
