ACI Concrete Sustainability Forum VIII
Koji Sakai and Julie K. Buffenbarger
The Concrete Sustainability Forum VIII was held in Denver, CO, at The ACI Concrete Convention and Exposition – Fall 2015. The forum included presentations by seven speakers, panel discussions between speakers and audience, and a tour of the National Renewable Energy Laboratory. The presentations, discussions, and tour are summarized.

Carbon-Negative Pilot
Yao Wang, Mija Hubler, Rakshita Ramesh Bhat, Wil V. Srubar III, Shane Frazier, Loren Burnett, Linfei Li, Ben Stanley, Ryan Dick, and Sean James
The article discusses testing of a system designed to achieve overall carbon negativity. The system comprises a concrete slab supporting a wall constructed using concrete masonry units (CMUs). The concrete slab was made of alkali-activated cement containing algae-derived carbon-storing, biogenic limestone. The CMUs contain biomineralizing microalgae and a proprietary hydrogel binder as cement replacement.

Early-Age Shrinkage Behavior of Portland Limestone Cement
Barrett, Timothy; Sun, Hongfang; Villani, Chiara; Barcelo, Laurent; and Weiss, Jason
This article summarizes the results of a study on the shrinkage behavior of an ordinary portland cement (OPC), a portland-limestone cement (PLC), and a PLC-Slag cement. The results show that the OPC, PLC, and PLC-Slag systems have similar early-age shrinkage, stress development, and cracking behavior, despite the higher fineness of the PLC. Eliminating the largest cement particles during the grinding/separation process used in the production of the PLC allows PLC mixtures to have pore size distributions that are similar to those for OPC mixtures.
