ACI Committees 130 and 224 sponsored and moderated two sessions at The ACI Concrete Convention and Exposition - Fall 2017, held in Anaheim, California. The objective of the sessions was to review the use of innovative mixture designs which incorporated sustainable admixtures and supplemental cementitious materials, and the effect these sustainable technologies have on the cracking performance and durability of these concretes. In particular, cracking behavior in sustainable concretes or practices for mitigation of cracking in sustainable concretes was reviewed. This information was shared based on completed research and case studies of sustainable concrete mixture designs. The learning objectives of the two sessions follow: 1) Learn about innovative mixture designs that incorporate sustainable admixtures and supplemental cementitious materials; 2) Learn about the effect these sustainable technologies have on the cracking performance and durability of these concrete mixes; 3) Gain an understanding of the cracking behavior of sustainable concrete mixtures; and 4) Learn about practices used to mitigate cracking in sustainable concrete.
