Low-Carbon Cements Committee
(IS-LCCC)
ICC 1155 Standard for Low-Carbon Alternative Cements Used in Concrete
The first edition of ICC 1155 is being developed under the Code Council’s ANSI Accredited Consensus Procedures.
The Code Council is developing this new performance standard for the assessment of low-carbon alternative cements used in concrete. The cement industry is responsible for about 8% of the CO2 emissions for the globe. With the increased attention to the effects of global CO2 production, there is a need 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).
