FURTHER LABORATORY STUDIES OF PORTLAND-POZZOLAN CEMENTS

This study augments an earlier one in which much of the same type of information on the properties of concretes made with early portland-pozzolan cements (ASTM Type IP) was presented. Three Type IP cements and two Type I cements were used in the earlier work. One of the Type I cements was manufactured at the same as one of the Type IP cements. The present study included six Type I cements and six Type IP cements made at six different plants. Each Type IP, therefore, can be directly compared with a Type I manufactured at the same plant at about the same time; consequently, the clinker portions of the counterpart cements should be very similar in composition. The data presented include results of chemical and physical tests of the cements according to ASTM C150 and C595 and data on the physical properties of the concretes, including strength development, drying shrinkage, resistance to freezing and thawing, and resistance to deicer scaling. Air-entrained concretes made with the portland-pozzolan cements were somewhat less resistant to deicer scaling than were the air-entrained concretes made with the Type I portland cements. However, resistance to freezing and thawing in water was similar with both types of cement. Drying shrinkage was somewhat less for the Type IP cement concretes. Both types of concrete exhibited similar compressive and flexural strength development.
