BT-303, a cutting-edge, slump-preserving polycarboxylic acid water reducer innovatively crafted by Shandong Gaoqiang New Material Technology Co., Ltd. This advanced formulation is engineered to effectively curb concrete slump loss, making it ideal for high water-reducing polycarboxylic acid reducers. BT-303 is versatile and is perfectly suited for a wide array of applications, including pumping concrete, super-fluid self-compacting, high-strength, high-performance concrete, and commercial concrete.
The brilliance of BT-303 lies in its sophisticated molecular structure, which integrates active groups like ester and amide groups. This synthesis results in a superplasticizer with exceptional slump retention. In the alkaline environment of concrete, ester groups are meticulously hydrolyzed into carboxylic acid groups, which then adsorb onto cement particles. This process ensures a superior slow-release slump protection, maintaining concrete quality over time.
Within the alkaline realm of concrete, the ingenious reactive groups in BT-303's molecular structure gradually release dispersing groups. This ongoing dispersion action effectively prevents slump loss, prolonging the workability and quality of concrete mixtures.
(1) Exceptional slump retention: BT-303 maintains a remarkable slump value, preserving over 80% of the fresh concrete's initial slump after one hour, offering a reliable solution to rapid slump loss challenges. Experience superior concrete quality with BT-303, as it ensures freshly mixed concrete exhibits excellent workability, along with enhanced hardening and long-lasting durability.
(2) Outstanding concrete performance: After integrating BT-303, freshly mixed concrete demonstrates superb workability, excellent hardening, and enduring durability.
(3) Broad adaptability: BT-303 is engineered to harmonize with a wide variety of cement types, including Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and diverse admixtures.
(4) Eco-friendly Production: BT-303 is produced with a commitment to environmental responsibility, generating no three waste products during manufacturing.

1. The recommended dosage ranges from 0.6% to 1.2% based on the total cementitious materials. For optimal results, determine the exact dosage through experimentation, considering specific engineering materials and characteristics. Suitable for use alone or in conjunction with high water-reducing polycarboxylic acid water-reducing agents.
2. While typically used in combination, BT-303 can be employed singularly or blended with water-reducing and set retarding mother liquors to combat slump loss. It can also be compounded with functional aids for admixtures with retarder, early strength, antifreeze, or pumping capabilities. Application methods should be validated through testing and compounding technology.
3. BT-303 is compatible with various admixtures like early strength agents, air entrainment agents, and retarders. Conduct a test prior to use for compatibility. It should not be mixed with naphthalene series water reducers.
4. When integrating active admixtures such as fly ash and slag into the concrete mix, calculate the amount of water-reducing agent based on the total cementitious materials for accurate dosing.
Packaging Options: Available in 220kgs/drum, 23.5 tons/Flexitank, 1100kg/IBC, or customized as per request, ensuring flexible and convenient delivery solutions.
Storage: To ensure maximum efficacy and longevity, store the BT-303 Slump Retention Type Superplasticizer in a well-ventilated, dry warehouse with temperatures maintained between 2 to 35 degrees. Ensure the packaging remains intact and unsealed to preserve its quality, with a commendable shelf life of one year. Protect the product from direct sunlight and freezing conditions to maintain its superior performance.
