ABSTRACT
Portland cement production is a major contributor to global CO2 emissions. Low-carbon cements, which typically involve the replacement of some of the ordinary Portland cement (OPC) in the mixture with supplemental cementitious materials (e.g., fly ash and/or slag), are a way to reduce the carbon footprint of masonry construction. Newly developed products can completely replace the OPC in cementitious materials. Such cement-free binders have very little CO2 emissions in their production process. This paper investigates the use of a low-carbon binder to create a fibrous mortar mixture that can be applied on the face of concrete masonry blocks as part of a structural upgrading technique. Mortar mixtures are designed and tested with a low-carbon binder to assess their viability as an alternative for developing low-carbon structural upgrading details.
