NEU Introduces The Low-Carbon Concrete Guide: Materials
.jpg)
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.

Sustainability and Durability of Solidia Cement Concrete
Sada Sahu and Richard C. Meininger
World cement production is estimated to contribute about 8% of total anthropogenic carbon dioxide (CO2) emissions worldwide. Solidia Cement™ (SC) is a new type of binder with a chemistry and functionality that allows it to have a significantly reduced CO2 footprint. The article describes the CO2 savings in the production of SC and CO2 used for curing of SC concrete.

Carbon-Neutral Concrete
Andrea Schokker
Carbon-neutral concrete and carbon-neutral cement involve different levels of scope. In the case of carbon-neutral cement, carbon reductions need to offset the emissions from cement production. The reduction of carbon footprint by the cement industry is critical to reducing the embodied carbon of the end product—concrete.

Equivalent Durability Performance of Portland Limestone Cement
Michael D.A. Thomas, Anik Delagrave, Bruce Blair, and Laurent Barcelo
This article, the third in a series on portland limestone cement (PLC), reports on the mechanisms that allow PLC mixtures to maintain the same levels of durability performance as portland cement (PC) mixtures. It discusses results of alkali-silica reactivity, sulfate resistance, freezing-and-thawing, scale resistance, and carbonation testing. PC and PLC used in presented studies came from the same mill circuit. The target limestone content of the PLC was 12%, the limestone was interground with the cement clinker, and the fineness of the PLC was increased to achieve the same 28-day (mortar) strength as the PC.
