The American Concrete Institute has formed ACI Committee 242, Alternative Cements, to develop and report information on the use of alternate cements in concrete. The new committee will work with ACI’s innovative task group focused on alternative cementitious materials, who recently authored the institute’s new ITG-10R: Practitioner’s Guide for Alternative Cements.
Chaired by University of Minnesota – Duluth Assistant Professor Mary Christiansen, ACI Committee 242 will develop a state-of-the-art report and ACI TechNotes on alternative cement technology; assemble case studies featuring alternative cements; define the distinction between alternative cements and alternative supplementary cementitious materials; and, develop a performance-based guide specification.
As performance and sustainability demands increase, owners, architects and engineers are actively seeking alternatives to the use of portland cement. In some cases, alternative cements may also be used in combination with portland or blended hydraulic cements. ITG-10R: Practitioner’s Guide for Alternative Cements covers currently available and emerging alternative cements and is intended to provide information to help guide practitioners seeking to implement alternative cements.
ACI committee 242 will be holding a mini-session titled “Recent Advances in Alternative Cements” at The Concrete Convention and Exposition in Las Vegas, October 14-18, 2018.
