Hydration heat development in blended cements containing fine-ground ceramics

▸ Hydration heat development in blended cements containing fine-ground ceramics is analyzed. ▸ Specific hydration heat of blended cements is up to two times lower than of Portland cement. ▸ Fine-ground ceramics slightly retards the C3S hydration process. ▸ Using more than 20% of ceramics in the blended cement is not effective.
