Abstract:This research assessed the applicability of Type IL cements satisfying AASHTO M 240 specifications for use in transportation applications in place of Type I/II cements which satisfy AASHTO M 85 specifications for construction of transportation structures. Type I/II and Type IL cements from five producers were investigated. The cements and both mortars and concretes made with these cements were studied to determine material characteristics; material properties including setting time, strength development, shrinkage, and permeability; and mechanical properties. The results showed the performance of concrete made with Type IL cement was affected by the cement fineness which increased strength and drying shrinkage. Type IL cement may be used in place of Type I/II cement when fineness values are specified.
