Angelus CarbonKind cmu significantly contribute to the intent of this pilot credit. A new LEED v4.1 Pilot Credit, Procurement of Low Carbon Construction Materials (MRpc132), provides means to account for and define reductions in the embodied carbon of materials, and ultimately the building. With data now available from CLF, comparisons to baselines are possible. Angelus Block is fully committed to advancing the sustainable contributions of concrete masonry and offers CarbonKind products without a cost premium. Reductions in CO 2e of 43% from industry medians, and 61% from the CLF baseline are outstanding!ĬarbonKind fully meets ASTM C90 and is available in all Angelus-produced CMU. The average impact for all Angelus CarbonKind MW products is used in the illustration. Medium Weight (MW) CMU are the predominant product type used in buildings. The Baseline Report includes values of kg CO 2e per m 3. To illustrate CarbonKind CO 2 reductions, we can look to our collection of EPDs and Carbon Leadership Forum’s 2021 CLF Material Baselines (v2) 1 which now includes CMU. It does not rely on nascent technologies that are not quite ready for a real-world marketplace. By reducing a portion of kiln-fired clinker, and replacing it – post kiln – with limestone, PLC reduces energy input and minimizes the CO 2 released by its production. With use of PLC and other production and material efficiencies, CarbonKind eliminates a good portion of CO 2 that would be typical of OPC products and provides low-carbon CMU produced with proven methods. PLC is getting increased attention as an alternative to OPC.
CarbonKind does not use higher-GHG ordinary Portland cement (OPC), but instead incorporates a blended cement, Portland-limestone cement, or PLC.
Common concrete block contains a much lower percentage of cement than ready-mix concrete, giving it a good head start as a carbon-reducing material.Īngelus Block has taken this further with CarbonKind, a concrete masonry unit (CMU) with substantially lower CO 2 impact. CarbonKind CMUĬoncrete masonry is recognized as an all-around performer – with seismic and fire resistance, durability, sound dampening, design flexibility, multiple functions, and cost benefits. CarbonKind by Angelus Block achieves the largest CO 2 reductions for CMU in the Southern California region.
