Overview
About
CASTAID CEM 855 is a specially formulated performance enhancer designed to accelerate early strength development in the production of both Portland and hydraulic cements. It provides a tailored solution for cement manufacturers seeking to optimize their processes.
Typical uses
CASTAID CEM 855 is recommended for the production of Ordinary Portland Cements (OPC) and blended cements using fly ash, GGBFS and other pozzolanic materials.
Standards
CASTAID CEM 855 meets the requirements of ASTM C465- 85.
Compatibility
CASTAID CEM 855 is compatible with all types of Portland cement and blended cement replacement materials such as GGBS, PFA and limestone, and with all CASTECH range concrete admixtures.
Benefits
Advantages
Key advantages
- Enhanced early strength and accelerated setting time of cement
- Boosted mill productivity through reduced cement grinding costs
- Improved efficiency of separator and classifier systems
- Improved specific energy consumption for greater operational efficiency
- Minimized cement agglomeration during grinding
- Decreased pack-set index (PSI), reducing silo blockage and cake formation
- Improved powder flowability for bulk transportation of cement
- Optimized cement particle size distribution (PSD) for improved product quality

Application
Dosage
Typical dosage rates of CASTAID CEM 855 are between 0.20 – 1.0 kg per tonne of cement (0.02 – 0.10% by weight of cement). Dosage may vary depending on clinker type, type of cement mill, desired mill output and cement performance. The optimum dosage rate should be determined during full- scale cement mill tests and actual plant use to meet the desired requirement.
Application
CASTAID CEM 855 is a ready-to-use liquid additive. Industrial trials are recommended to determine the ideal dosage for specific requirements. It can be introduced directly into the mill or onto the feed for Ordinary Portland and Blended Cements conveyor belt. For continuous processes, dose with a volumetric dosing pump to ensure a consistent output and precise
Packaging & storage
Packaging
CASTAID CEM 855 is available in IBC, 200 kg drums and bulk tanks upon request.
Storage & shelf life
12 months from date of manufacture when stored under warehouse conditions in original unopened packing. Extreme temperature/humidity may reduce shelf life.
Health & safety
