Type IL: Portland-Limestone Cement
Type IL Portland Cement is uniquely formulated to reduce the environmental footprint of Portland Cement. This cement is manufactured by intergrinding portland cement clinker with up to 15% limestone. Blended cements such as Type IL are used in all aspects of concrete construction in the same manner as portland cements. Blended cements can be used as the sole cementitious material in concrete or they can be used in combination with other supplementary cementitious materials added at the concrete plant. Laboratory tests indicate that the performance of concrete made with Type IL cement as a group is similar to that of Type I/II (MH) cement concrete.
