Carbon Neutrality and Sustainability Design of Concrete Structures

Koji Sakai, Japan Sustainability Institute

Carbon neutrality is an essential part of sustainable concrete construction. Sustainability in the use of concrete structures is realized by the application of performance-based sustainability design. Regarding carbon reduction towards carbon neutrality, an appropriate transition design is indispensable as there is no magic. The essence of de-carbon neutral turmoil is clarified on the basis of a transition design.

Reducing the GWP of Concrete: Thoughts on Reactivity, EPDs and Optimization

Dr Jason Weiss, Professor, Oregon State University

Concrete materials and mixture proportions are changing to reduce the global warming potential (GWP) associated with concrete production. To reduce the GWP of concrete the industry is moving to replace cement clinker with supplementary cementitious materials (SCM, e.g., natural pozzolans, recycled glass, industrial by-products, or carbonated cement fines) that are emerging to reduce the GWP of concrete mixtures. This presentation will discuss the need for accurate quantification of the reactivity of these materials. Calculation of the environmental product declaration (EPD) of concrete will be discussed along with the shortcomings of using this approach.

Demonstrating Low Carbon Concrete for Tilt-Up Wall Panel Construction

Tom Van Dam, Wiss, Janney, Elstner Associates, Inc.

The results of a low-carbon concrete tilt-up wall panel demonstration project will be presented that evaluated three concrete mixtures: a base level Type IL (Mix#1), the Type IL with 25% replacement with slag cement (Mix #2), and an ASTM C1157 cement with less than 5% portland cement (Mix#3). Extensive laboratory testing determined the bleed rate, initial and final set, compressive strength, splitting tensile strength, modulus of elasticity, and drying shrinkage of the three mixtures as well as establishing maturity relationships. Considerable information was obtained through testing and in situ monitoring providing lessons on how to use concrete with significantly lower carbon even under difficult temperature conditions.

A Look at Low-Carbon Cement and Concrete in the Construction Industry

Dean Frank, PE, Executive Director, NEU

This presentation will provide a brief update on current projects being coordinated by NEU: An ACI Center of Excellence for Carbon Neutral Concrete, which was established by the American Concrete Institute to collaborate globally to drive education, awareness, and adoption of the use of carbon-neutral concrete materials and technologies. Topics will include a brief overview of NEU, the status of the NEU Validation/Verification Program, and a summary of a recent survey of suppliers of materials and technologies.

General Presentation

Low Carbon Aspects of Alternative Reinforcement Systems

Barzin Mobasher, PE, FACI, FRILEM, Arizona State University

Barzin Mobasher, PE, FACI, FRILEM, Arizona State University, discusses alternative reinforcements such as fibers, textiles, and fiber-reinforced polymer (FRP) as well as hybrid designs that tend to reduce the amount of rebars used by means of conventional design approaches and make a significant improvement in the overall load-carrying capacity while reducing the overall carbon footprints. New test methods are presented to validate the potential benefits by identifying the controlling mechanisms. Several applications developed in the past five years are highlighted as case studies and showcase the significant cost savings, enhanced performance, and carbon emissions reduction.
