cement clinker is in super high strength,early strength,low alkaline,fast setting time,rapid hardening,frost and corrosion resistance.
Additionally, cement clinker are sometimes used in shrinkage compensated concrete by mixing with portland cement and for controlled low-strength materials (CLSM) used for diggable back-filling of utility trenches.
The product obtained by grinding cement clinker obtained by roasting suitable raw material, consisting essentially of anhydrous calcium sulphoaluminate and dicalcium silicate. Suitable gypsum and 0-10% limestone shall be blended with clinker during manufaturer of rapid-hardening sulphoaluminate cement. The rapid-hardening cement product is hydraulicity binding material. It has high early strength. The code no is R-SAC and with four grades.
High-efficiency csa expansive agent is obtained by blending suitable natural anhydrite with a specially manufactured clinker which consists essentially of calcium sulphoaluminate and CaO. Csa expansive agent is always mixed with ordinary cement. When mixed in the proper proportions with ordinary cement and hydrated, cement mortar or concrete expands during the early stages of hydration.
