The ASTM C595-12 Standard Specification for Blended Hydraulic Cements defines requirements for a new powder: Type IL, portland-limestone blended cement, which includes 5% to 15% limestone as an ingredient. Adoption of Type IL product has the potential to reduce environmental impact of cement production by about 10%, while maintaining performance characteristics concrete producers require for specified mixes. The requirements for Type IL cement are the most significant change to C595 in 2012.
