LC3 and the LC3-Project
Limestone calcined clay cement (LC3) is a ternary blended cement that is composed of portland cement, calcined clay, limestone and gypsum. It offers:

Enhanced strength and durability properties in comparison with other conventional blended cements.
Up to 40% reduction in CO2 emissions. As a blended cement, about half the portland cement clinker is replaced with calcined clay and limestone resulting in a substantial reduction in embodied carbon.
Allow utilization of low-quality clays and limestone
Minimal capital investment for production
A viable alternative for cement and concrete producers where other supplementary cementitious materials (SCMs) such as fly ash and slag cement are not available.

Initiated by research in 2005, the LC3-Project was formally established in 2014 with the objective to, through research and testing, make LC3 a standard and mainstream general-use cement in the global cement market. Initial phases of the Project have sought to demonstrate technical feasibility and facilitate industry adoption. You can read more about the project on the LC3 website.

LC3 Technical Resource Centers
In support of this purpose, the LC3 developers' group has established technical resource centers (TRCs), located in Africa, Latin America, Asia and now at WJE for North America. These TRCs focus on knowledge sharing, technology and provide a variety of consulting and testing services to industry clients related to the development, and application of LC3.
