Clinker: compositional parameters - Understanding Cement

Silica Ratio (SR) The Silica Ratio (also known as the Silica Modulus) is defined as: SR = SiO 2 /(Al 2 O 3 + Fe 2 O 3) A high silica ratio means that more calcium silicates are present in the clinker and less aluminate and ferrite. SR is typically between 2.0 and 3.0. Alumina Ratio (AR) The alumina ratio is defined as: AR=(Al 2 O 3 /(Fe 2 O 3)
