BT-303, a revolutionary advancement in slump-preserving polycarboxylic acid water reducers, meticulously developed by Shandong Gaoqiang New Material Technology Co., Ltd. This innovative product dramatically curtails concrete slump loss, rendering it ideal for high water-reducing needs. Perfectly suited for applications in pumping concrete, ultra-fluid self-compacting, high-strength, high-performance, and commercial concrete, BT-303 is your go-to solution for exceptional concrete performance.
The ingenious molecular design of BT-303 incorporates active groups like ester and amide groups, creating a polycarboxylic acid superplasticizer with unparalleled slump retention capabilities. In the alkaline milieu of concrete, these ester groups gradually transform into carboxylic acid groups, adhering to cement particles. This results in an extraordinary slow-release slump protection mechanism, ensuring sustained workability and performance.
Under concrete's alkaline condition, this product's reactive molecular groups consistently release dispersing agents. This continuous dispersion of cement prevents slump loss, ensuring durable and stable concrete mixtures.
(1) BT-303 offers outstanding slump retention, maintaining over 80% of the initial slump of fresh concrete after one hour, effectively addressing rapid slump loss challenges. This feature ensures that concrete retains its fluidity and workability for extended periods, facilitating seamless construction processes.
(2) Post-application, concrete exhibits superior workability and hardening, along with enhanced durability, providing long-lasting, robust structures.
(3) Exceptional adaptability to various cement types, including Portland, slag silicate, fly ash, and pozzolan, as well as diverse admixtures, makes BT-303 versatile for numerous applications.
(4) Environmentally conscious, BT-303's production process is devoid of any hazardous waste, promoting a sustainable and green approach.

1. Recommended dosage ranges from 0.6% to 1.2% of the total cementitious materials. Optimal dosage should be determined through tailored experimentation based on specific engineering materials and conditions. BT-303 can be effectively combined with high water-reducing agents or utilized independently.
2. Typically, BT-303 is not used alone but can be mixed with water-reducing and set-retarding agents to mitigate slump loss. Alternatively, it can be compounded with functional additives to create formulations with retarder, early strength, antifreeze, or pumping properties. Appropriate usage should be validated through testing and compounding methodologies.
3. BT-303 is compatible with various admixtures including early strength agents, air entrainers, and retarders. Prior testing is essential to ensure compatibility. Avoid combining with naphthalene series water reducers.
4. When concrete mixes include active admixtures like fly ash or slag, the water-reducer dosage should be calculated based on the total cementitious content.
Packaging options include 220kgs per drum, 23.5 tons per Flexitank, or 1100kg per IBC, with customization available upon request.
Storage: Ensure optimal preservation by storing the product in a well-ventilated, dry warehouse with temperatures ranging from 2 to 35 degrees Celsius. Maintain the integrity of its packaging by keeping it sealed. When stored correctly, the product boasts a shelf life of one year.
