• Explained: Cement vs concrete — their differences,

    Since concrete is the most popular material in the world and cement is the primary binder used in concrete, these two sources of CO 2 are the main reason that cement contributes around 8 percent of global emissions CSHub’s Executive Director Jeremy Gregory, however, sees concrete’s scale as an opportunity to mitigate climate change

  • Use of cement in concrete according to European

    The concrete technology measures to be taken refer mostly to the maximum w/c ratio, the minimum cement content, the minimum concrete strength class, application rules for concrete additions and, in individual cases, by the limitation of usable cements, which must be maintained depending on the respective exposure class
