NRMCA and the Concrete Advancement Foundation have published the August 2024 Investigation for the Validation of Increased Rebar Spacing in Concrete Walls. The report, authored by Dr. Julian Mills-Beale, NRMCA director, codes and standards, explores the possibility of optimizing rebar area and spacing in reinforced concrete walls, including insulated concrete form (ICF) walls commonly used in low- and mid-rise construction.
The research is intended to benefit industry through more sustainable and economic concrete wall designs based on reinforcement ratios with increased spacing. The report documents initial findings with further investigations being considered for the next phase. The report is available for download from the Foundation’s website or NRMCA’s website.
The NRMCA Codes and Standards teams manages research projects in collaboration with the Concrete Advancement Foundation to support its codes and standards advocacy efforts. For more information regarding the rebar spacing study, contact Dr. Julian Mills-Beale at jmills-beale@nrmca.org.
