The American Concrete Institute (ACI) has formed a committee to develop and report information on the use of alternate cements in concrete. The 242 Alternative Cements group will be chaired by Mary Christiansen.
This team will aim to develop a 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. They will also work with ACI’s task group who focus on alternative cementitious materials.
An alternative cement is intended to be a replacement for Portland cement in some applications. In some instances, alternative cements could be used in combination with Portland or blended hydraulic cements. The ITG-10R: Practitioner’s Guide for Alternative Cements, published by the task group, covers available and emerging alternative cements and is intended to help practitioners seeking to implement alternative cements.
On 14 October, the committee will host a session titled Recent Advances in Alternative Cements at The Concrete Convention and Exposition in Las Vegas.
