| 摘要： | For the construction industry, the current conversation about sustainabil-ity revolves primarily around the initial embodied carbon (EC) in the materials we use to construct projects. That is the extraction, transportation, and manufacture of the materials. The perception that concrete is a high embodied carbon (EC) material creates a challenge. This comes from a failure to distinguish concrete from Portland cement. While Portland cement has high EC, cement is one of several ingredients in concrete, and those other ingredients have a much lower EC. In fact, Portland cement accounts for nearly 90% of the EC in a typical concrete mix, but compared to other common road and bridge construction materials, it has a low to moderate amount of EC per unit of material. |
