BT-303 is a state-of-the-art, cutting-edge slump-preserving polycarboxylic acid water reducer, meticulously crafted by Shandong Gaoqiang New Material Technology Co., Ltd. This innovative solution is engineered to profoundly curb the slump loss in concrete, making it exceptionally effective for high water-reducing applications. Its versatility allows it to seamlessly integrate into a wide array of concrete formulations, such as pumping concrete, ultra-fluid self-compacting concrete, and high-strength, high-performance commercial concrete.
The molecular design of BT-303 introduces dynamic active groups, notably ester and amide groups, yielding a polycarboxylic acid superplasticizer with outstanding slump retention capabilities. Within the alkaline environment of concrete, ester groups undergo gradual hydrolysis, transforming into carboxylic acid groups that adhere to cement surfaces. This results in an exceptional slow-release mechanism that skillfully protects against slump loss.
Under the alkaline conditions prevalent in concrete, the reactive molecular groups of this product engage in a controlled release, effectively dispersing cement particles. This continuous dispersion significantly mitigates the rate of slump loss, ensuring prolonged workability and resilience in concrete structures.
(1) The product boasts a remarkable slump retention value, maintaining over 80% of the initial slump even after an hour, thereby effectively countering the common issue of rapid slump loss in concrete. This capability ensures that the concrete remains workable and efficient, even over extended periods, enhancing both its usability and performance.
(2) Post-application, the concrete demonstrates exceptional performance. The fresh mix not only offers superb workability but also excels in hardening and durability, establishing a robust and enduring structure.
(3) Exhibiting wide-ranging compatibility, the product adapts seamlessly to Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and various admixtures, optimizing flexibility across different formulations.
(4) Emphasizing sustainability, the production process is environmentally conscious, producing no waste byproducts, thereby contributing to a greener planet.

(3) Suitable for diverse industrial and civil construction scenarios and commercial concrete mixing plants, facilitating robust and innovative construction solutions.
1. Typically, the recommended dosage is between 0.6% and 1.2% of the total cementitious material, with optimal amounts best determined through empirical testing based on specific engineering requirements. It can be effectively paired with high water-reducing polycarboxylic acid agents or utilized independently, offering flexibility in application.
2. While single use is possible, BT-303 can be synergistically combined with water-reducing and set-retarding mother liquors to mitigate slump loss. Additionally, it can be compounded with functional aids to formulate admixtures that impart retarder, early strength, antifreeze, and pumping benefits. Application specifics should be verified through testing and compounding methodologies.
3. BT-303 can be integrated with other admixtures like early strength agents, air entrainment agents, and retarders; however, compatibility testing is essential prior to use. It should not be mixed with naphthalene series water reducers to maintain efficacy.
4. When active admixtures such as fly ash and slag are present, the amount of the water-reducing agent must be calculated inclusive of the total cementitious materials to ensure optimal performance.
Package: Available in 220 kg drums, 23.5 tons per Flexitank, 1100 kg IBC, or customized packaging upon request, ensuring flexible and efficient delivery solutions.
Storage: To maintain peak performance and longevity, store the BT-303 Superplasticizer Liquid in a well-ventilated, dry warehouse with a temperature range of 2-35 degrees Celsius. Ensure the packaging remains intact and unopened for a shelf life of one year. Shield the product from direct sunlight and freezing conditions to preserve its efficacy.
