BT-303, a cutting-edge, next-generation slump-preserving polycarboxylic acid water reducer, meticulously developed by Shandong Gaoqiang New Material Technology Co., Ltd. This innovative solution is expertly formulated to dramatically curb concrete slump loss, ensuring optimal performance. It is perfectly tailored for high water-reducing applications, making it an ideal choice for pumping concrete, super-fluid self-compacting scenarios, as well as high-strength and high-performance concrete and commercial concrete applications.
Harnessing the power of an advanced molecular structure, this product integrates active ester and amide groups to craft a polycarboxylic acid superplasticizer with exceptional slump retention capabilities. In the alkaline environment of concrete, the ester groups undergo a gradual hydrolysis process, transforming into carboxylic acid groups, which are then adeptly adsorbed onto the cement particles' surface, delivering a superior slow-release and protective effect against slump.
In alkaline concrete conditions, the reactive groups in this product's molecular structure strategically release dispersing components over time, perpetuating the dispersal of cement and effectively mitigating concrete slump loss, ensuring sustained workability and performance.
(1) Exceptional slump retention properties, maintaining over 80% of the initial slump in fresh concrete one hour post-mixing, thus effectively addressing and solving rapid slump loss challenges. This ensures that the fresh concrete retains its workability and fluidity, facilitating ease of use and application.
(2) Remarkable concrete performance post-application. Fresh concrete exhibits excellent workability, whilst hardened and durable concrete characteristics are enhanced.
(3) Versatile adaptability to a diverse range of cements, including Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and various admixtures, ensuring flexibility in application.
(4) Environmentally conscious production, featuring green credentials with no three waste products generated during the manufacturing process, promoting sustainability.

(3) Ideal for use in various industrial and civil construction projects as well as commercial concrete mixing plants, delivering consistent quality and performance across applications.
1. The recommended dosage is between 0.6% to 1.2% (based on the total cementitious materials), with the optimal amount determined through experimentation according to specific engineering materials and characteristics. It can be paired with high water-reducing polycarboxylic acid agents or utilized alone for maximum effectiveness.
2. This product can be used independently (under specific conditions) or combined with water-reducing and set-retarding agents to minimize concrete slump loss. Additionally, it can be compounded with functional additives to create admixtures with retarder, early strength, antifreeze, and pumping capabilities. Testing and compounding technology should guide the application method and conditions.
3. Compatible with other admixtures like early strength agents, air entrainment agents, and retarders. It is crucial to conduct thorough testing before use to ensure compatibility. Avoid mixing with naphthalene series water reducers to maintain product integrity and performance.
4. When incorporating active admixtures such as fly ash and slag into the concrete mix, calculate the water-reducing agent amount based on the total cementing materials to optimize performance and effectiveness.
