International Session: Seawater Concrete and Innovative Ideas for Sustainable Concrete

Sunday, November 3, 2024  1:30 PM - 3:30 PM, Grand BR Salon A

The aim of the session is to present the most recent developments and challenges in the adoption and use of a sustainable and durable concrete made from appropriate binders, saltwater, chloride-contaminated recycled concrete aggregates, modified fine aggregates (sand dunes), and coarse lightweight pet-coke aggregates reinforced with polymer-based non-corrosive reinforcement. The session will provide the opportunity to announce formation, scope and objectives of a recently-established consortium named NovusCrete as well as the ACI Technical Committee 243 – Seawater Concrete.

Following the four presentations (15-minute each) a round table discussion will take place allowing the audience to interact with the panelists.

Learning Objectives:
(1) Understand the composition and properties of the concrete mix incorporating saltwater, sand dunes, recycled coarse aggregates, and GFRP;
(2) Explore the benefits and limitations of using saltwater as a component in concrete mixtures, including its impact on durability, strength, and sustainability;
(3) Evaluate the role of GFRP reinforcement in enhancing the performance and durability of concrete structures, considering its advantages over traditional steel reinforcement;
(4) Address the sustainability aspects of the developed concrete mix, including its potential for reducing carbon emissions, and conserving natural resources.
