Sources: CalPortland Co., Glendora, Calif.; CP staff

The two charter offerings in a new CalPortland line of blended portland-limestone cements (PLC) have an embodied carbon level about 10 percent below that of common ASTM C 150 materials. ADVANCEMENT LT (Light) is a lighter colored, higher albedo Type IL PLC suiting concrete in design and architectural conditions. ADVANCEMENT HS (High Sulfate) is formulated for general use concrete or when high sulfate resistance is required.

CalPortland documents glaring greenhouse gas accounting void

Paper cropped

In a new paper summarizing peer-reviewed scientific studies, CalPortland Co. staff cites the exclusion of a critical factor in global, national, and regional greenhouse gas accounting methods: Concrete buildings, pavements and structures are silently absorbing carbon dioxide from the atmosphere—to such an apparent degree that the built environment represents one of the world’s largest carbon storehouses.

CalPortland states case for carbonation line item in GHG accounting

Sources: CalPortland Co., Glendora, Calif.

In a recent paper summarizing peer-reviewed scientific studies, the staff of key West Coast cement, aggregate and ready mixed producer CalPortland cites the exclusion of a critical factor in global, national, and regional greenhouse gas accounting methods: Concrete buildings, pavements and structures’ silent absorption of carbon dioxide from the atmosphere—to such an apparent degree that the built environment represents one of the world’s largest carbon storehouses. While considerable attention has been paid to quantifying the industrial phase emissions from cement production, authors observe, the natural reversal process of CO2 uptake during concrete’s complete material service life is just beginning to receive the consideration it deserves.
