Assessment of Type IL Cements for Transportation Applications Ahmad Shalan, Elizabeth Nadelman, Kimberly E. Kurtis, Lawrence F. Kahn School of Civil and Environmental Engineering, Georgia Institute of Technology Introduction Future Work This work is supported by the Georgia Department of Transportation under project number GDOT Both AASHTO and ASTM have recently approved significant changes to their specification for cements or blended cements, allowing an increase in the allowable mass of ground limestone (CaCO 3 ) in some portland cement to approximately 15% by mass, creating what are known as “limestone blended cements”, or “Type IL cements.” This research will compare regionally produced limestone blended cements with conventional portland cements in terms of composition and fineness, evaluate the influence of increasing ground limestone addition rates through the assessment of key material properties, examine the relative sensitivity of those properties to field conditions, and assess the combinations of limestone blended cements with fly ash and slag. Compare material and early age properties of regionally produced Type IL limestone cements to those of Type I ordinary portland cements with similar chemical compositions. Evaluate the performance of Type IL concretes conforming to GDOT specifications for Class A, AA and AAA concrete.

Examine the sensitivity of Type IL concrete properties to variations in mixing temperature and curing conditions. Assess the performance of concretes containing various dosages of supplementary cementitious materials such as fly ash and slag.
