Introducing BT-303, an innovative advancement in slump-preserving polycarboxylic acid water reducers, meticulously developed by Shandong Gaoqiang New Material Technology Co., Ltd. This groundbreaking product excels in curbing slump loss, ensuring enduring workability in concrete applications. Its versatility is remarkable, making it a prime choice for high water-reducing scenarios, including pumping concrete, super-fluid self-compacting, high-strength, high-performance, and commercial concrete, where it delivers unparalleled results.
Crafted with a sophisticated molecular architecture, BT-303 incorporates active groups such as ester and amide, culminating in a superplasticizer with exceptional slump retention prowess. Amid concrete's alkaline environment, these ester groups gradually transform into carboxylic acid groups, adhering seamlessly to cement particles. This dynamic interaction activates an effective slow-release mechanism, maintaining the desired slump with finesse.
In the alkaline realm of concrete, BT-303's molecular structure subtly releases dispersive reactive groups. This controlled release ensures continuous cement dispersion, thus masterfully preventing premature slump loss and sustaining concrete's ideal consistency throughout its application.
(1) Exceptional Slump Retention: BT-303 boasts substantial retention capabilities, maintaining over 80% of the initial slump after one hour, effectively addressing the challenge of rapid slump loss in concrete. This feature ensures that the fresh concrete remains pliable and workable, providing remarkable ease during application.
(2) Superior Concrete Performance: Post-application, the concrete exhibits enhanced workability, coupled with excellent hardening and durability, making it a preferred choice for enduring constructions.
(3) Broad Compatibility: BT-303 showcases remarkable adaptability across diverse cement types, including Portland cement variants, slag silicate, fly ash cement, and pozzolan cement, alongside numerous admixtures.
(4) Environmentally Conscious: Emphasizing sustainability, BT-303 is produced without generating any of the three waste pollutants, aligning with eco-friendly manufacturing practices.

(1) BT-303 is perfectly suited for preparing a wide array of concrete types, ranging from early-strength and retarded to precast and cast-in-place variants. It excels in large flow, self-compacting, mass, and high-performance concrete applications, while being particularly advantageous for low-grade commercial concrete in both industrial and civil buildings.
(2) Its versatility extends to national and key infrastructural projects, finding utility in high-speed railways, nuclear power, water conservancy, hydropower, subways, large bridges, expressways, harbors, and wharfs.
(3) Ideal for diverse construction types, BT-303 is a valuable asset in both industrial and civil construction, as well as commercial concrete mixing plants, ensuring optimal results across varied projects.
1. The recommended dosage ranges from 0.6% to 1.2%, calculated based on the total cementitious material weight. However, optimal usage is best determined through experimental trials tailored to specific engineering materials and project characteristics. BT-303 can be used alone or compounded with high water-reducing polycarboxylic acid agents.
2. Although usually not used solely, BT-303 can be combined with water-reducing or set-retarding mother liquors to mitigate concrete slump loss. It can also be blended with functional aids to craft admixtures with retarder, early strength, antifreeze, or pumping capabilities. For precise application, thorough testing and compounding technology should guide usage.
3. BT-303 can complement other admixtures like early strength agents, air entrainment agents, and retarders. Prior testing is crucial to ensure compatibility. Notably, avoid combining with naphthalene series water reducers.
4. In concrete mixes containing active admixtures like fly ash and slag, the water-reducing agent should be computed as part of the total cementitious material content.
Packaging options include 220 kg drums, 23.5-ton Flexitanks, or 1100 kg IBCs, with custom packaging available upon request to suit diverse logistical needs.
Storage Guidelines: Ensure that this valuable product is stored in a well-ventilated, dry warehouse with a temperature range of 2-35 degrees Celsius. Keep packaging intact and unopened to maintain its quality. With a shelf life of one year, it is essential to protect the product from direct sunlight and prevent freezing.
