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)

Explained: Cement vs. concrete — their .

03.04.2020 · Of course, notes Ulm, reducing the water-to-cement ratio for HPC also requires more cement. And depending on how that cement is produced, this can increase the material's environmental impact. This is in part because when calcium carbonate is fired in a kiln to produce conventional cement, a chemical reaction occurs that produces carbon dioxide (CO 2 ).
