Cs To Cs Ratio For Better Cement Grinding

  • Cement strengths | VVM
    Cement strengths | VVM

    Cement strengths. The strength development of a cement is not only defined by the composition but also by the grinding fineness, divided into classes (32.5 - 42.5 - 52.5). This classification takes place based on a pressure test after 28 days. Within each strength class the performances define from an early stage the distinction between the

Therefore, Type II cement, which is intended for moderate sulfate resistance, is allowed a maximum C 3 A content of 8%. Similarly, Type V cement, which is intended for high sulfate resistance, is allowed a C 3 A content no greater than 5%.. Early-age strength
