Low-Carbon Cements Committee
(IS-LCCC)
ICC 1155 Standard for Low-Carbon Alternative Cements Used in Concrete
Project Description: The Code Council is developing this new performance standard for the assessment of low-carbon alternative cement properties and its effects on concrete mechanical and durability properties based upon the ICC-ES Acceptance Criteria for Low Carbon Alternative Cements for use in Concrete (AC529).
Project Need: The cement industry is responsible for about 8% of the CO2 emissions around the world. With the increased attention to the effects of global CO2 productions, there is a needs for low carbon alternative cement that has the proper physical properties in accordance with model building codes and the referenced standards within. A standard will provide requirements for those physical properties that could be referenced in the International Building Code (IBC).
