Chemical Formula: C2H2CaO4 (White or slightly yellowish free-flowing powder)
Overview: A new low-temperature early-strength accelerator that significantly enhances cement early strength and shortens setting time. Widely used in mortars, plastering, repair, waterproofing, flooring, and concrete.
Core Features: Shorten setting time | Increase early strength | Remarkable low-temp performance | Improve durability | Fast dissolution | Excellent fluidity
Main Uses: Used in construction mortars and concrete to accelerate hardening and shorten setting time, especially in winter construction to enable faster demolding.
Recommended Dosage: Approx. 0.5%-1.0% per ton of cement mortar/concrete (max 2.5%). Adding 0.3%-0.5% in summer still yields noticeable early-strength gains.
Shortens initial setting time.
Normalizes delayed setting phenomena under low-temperature conditions.
Increases early-strength growth rate.
Shortens mold retention time in precast concrete production.
Shortens the time required for concrete to reach load-bearing capacity.
Application Fields: Construction Mortar, Tile Adhesive, Repair Mortar, Waterproof Mortar, Concrete Products, Oil & Gas Extraction Auxiliary.
Storage: Store in a cool, dry place; use within 6 months.
Processing: Do not exceed 2.5% of cement weight; conduct suitability trials prior to use.
Packaging: 25 kg / Paper Bag
