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.

Concrete Q & A: Using Portland-Limestone Cement in Concrete Repair Concrete
Achieving the designed service life of a repair depends on several factors including the material selection. This month’s Q&A discusses using portland-limestone cement instead of specified portland cement to repair concrete severely damaged by freezing-and-thawing cycles and corrosion due to exposure to deicing salts. The repair is expected to last at least 30 years.

Lowering Carbon Footprint While Achieving Frost- Resistant Concrete
Emmanuel K. Attiogbe, Tara L. Cavalline, and Adam D. Neuwald
The use of a mineral-blended polymeric microsphere powder in concrete mixtures can provide protection from freezing-and-thawing (F-T) damage as well as lower the carbon footprint of concrete. The article presents results of compressive strength and cyclic F-T testing for microsphere and air-entrained concretes containing two levels of fly ash as a supplementary cementitious material.

Products & Practice Spotlight: Sustainability Quest Yields Ultra-High-Performance Solution
Larry Rowland, Michele Di Marino, and Jesper Sand Damtoft
A shrinkage-reduced, self-consolidating, high-performance concrete that can be used for production of thin elements with high aesthetic, mechanical, and durability performance requirements was recently developed. The prepackaged dry mixture comprises Aalborg White® portland cement, ground carbonate, and reactive metakaolin. The combination results in high performance as well as a low CO2 footprint.
