NEU Introduces The Low-Carbon Concrete Guide: Materials

NEU's new guide focuses on practical, data-driven strategies for reducing the carbon footprint of concrete with emphasis on the material and mixture decisions that designers, engineers, contractors, and policymakers make at the project level.
Low-Carbon Concrete Materials Available to Reduce CO2 Emissions of Concrete
Many solutions exist to produce low-carbon concrete. One such solution is the increased use of supplementary cementitious materials (SCMs) and alternative cements.

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.

Products & Practice Spotlight: Can We Make Concrete without Cement?
Mehrdad Mahoutian, Chris Stern, and Yixin Shao
Steel furnace slag, a by-product of the steelmaking process, can be used as a portland cement replacement in production of concrete masonry units (CMUs). Even though steel furnace slag lacks cementitious or pozzolanic properties, it gains strength when exposed to CO2 in the presence of water. The article discusses technology for manufacturing CMUs using steel furnace slag as a total cement replacement.

ACI Concrete Sustainability Forum Celebrates 10 Years
Koji Sakai and Julie K. Buffenbarger
ACI Concrete Sustainability Forum X was held in 2017 at The ACI Concrete Convention and Exposition in Anaheim, CA. The Forum featured presentations from eight speakers, including the presidents of both ACI and fib. Presented topics included sustainability activities within ACI, fib, and ISO, new technologies for sustainability, and actions for the next decade.
