Abstract
The major components of Portland cement are two calcium silicates: Ca3SiO5 and beta-Ca2SiO4. Tricalcium silicate accounts for about 40% of Portland mass while dicalcium silicate represents 20%. Rich-belite cements are hydraulic materials, where the concentration of beta-Ca2SiO4 is higher than conventional cement. It shows a growing interest due to the saving of energy and raw-materials. O…
