LIMESTONE CALCINED CLAY CEMENT (LC3)
LC3 / LC2 a Breakthrough Technology to Lower CO2
Karen Scrivener, Professor, Construction Materials Laboratory, EPFL, Lausanne, Switzerland
By far the most feasible option to reduce CO2 from cements is to partially replace the CO2 intensive clinker component with substitutes. The supply of traditional substitute materials – slag and fly ash is decreasing steadily. Calcined clay is an excellent alternative to slag an fly ash, and is abundant worldwide. It reacts much faster than either slag or fly ash and the synergy for a coupled substitution with limestone is of particular interest. This combination of limestone, calcined clay and cement is called LC3 and the combination of limestone and calcined clay for use as and SCM, LC2. In this presentation I will explain the technology, its advantages and disadvantages.

INNOVATIVE PAVEMENT SYSTEMS
Innovations in Concrete Pavements
Brian Killingsworth, Executive Vice President, NRMCA
Early forms of concrete were used by the ancient Egyptians and a few millennia later by the Romans. Modern concrete has been in existence since 1824 and the first concrete street in American was built in Bellefontaine, Ohio in 1891. While the basic components of concrete (rock, sand, water, and cement) have not changed, there have been many material, design, and construction innovations that allow us to optimize its use. This session will focus on concrete pavement innovations that positively impact the cost, environment, opening time, and ease of construction and also touch on the future of concrete paving.
The Role of US Pavement Life Cycle in Decarbonization
Hessam Azarijafari, Deputy Director, MIT Concrete Sustainability Hub
Low carbon emissions policies and solutions are centered around the industries' and buildings' life cycle emissions. Limited tools and assessment methods commonly prevent pavement solutions from being considered for decarbonizing the United States. In order to achieve net-zero emissions and a decarbonized economy, pavements have a critical role to play. In this presentation, we will discuss the life cycle of pavements, their GHG emissions, and the potential for reducing these emissions by involving multiple stakeholders in the design, materials, and asset management of pavements. Additionally, we will introduce the Streamlined MIT Pavement LCA Tool, which allows engineers and planners to quantify the GHG emissions of different pavement options and scenarios. Using the nationwide case study of pavement network decarbonization, we will demonstrate how the LCA can be used to analyze and reduce pavement life cycle emissions.
