Presenting BT-303, a revolutionary breakthrough in slump-preserving technology from Shandong Gaoqiang New Material Technology Co., Ltd. This advanced polycarboxylic acid water reducer has been meticulously engineered to dramatically curb concrete slump loss. Tailor-made for high water-reducing applications, BT-303 is the ultimate solution for pumping concrete, super-fluid self-compacting systems, and high-strength, high-performance commercial concrete.
This product's molecular structure ingeniously incorporates active ester and amide groups, culminating in a polycarboxylic acid superplasticizer renowned for its slump retention prowess. Within the alkaline milieu of concrete, these ester groups methodically hydrolyze into carboxylic acid groups, adhering to the cement particles. This process ensures a superior slow-release, slump-protective effect that stands the test of time.
In the alkaline environment of concrete, the dynamic reactive groups within this product's molecular configuration progressively release dispersing agents. This action continuously disperses the cement particles, effectively curbing concrete slump loss and ensuring sustained performance.
(1) Exceptional slump retention capabilities! The slump value can remarkably maintain over 80% of the fresh concrete's original slump even after 1 hour, tackling the challenge of swift slump loss head-on with unparalleled efficiency. This cutting-edge feature ensures that the fresh concrete retains its desirable workability, delivering outstanding hardening and durability.
(2) Offers unmatched concrete performance post-application. Experience superior workability in fresh concrete, alongside exceptional hardening and durability qualities.
(3) Versatile adaptability! Seamlessly integrates with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, and pozzolan cement, as well as various admixtures, making it a versatile choice for diverse applications.
(4) Commitment to sustainability with green production! Our process is environmentally friendly, ensuring zero waste byproducts, aligning with eco-conscious values.

1. The recommended dosage ranges from 0.6% to 1.2% (calculated based on the total cementitious materials). Determine the optimal dosage through experimental testing to suit engineering materials and project requirements. It can be combined with a high water-reducing polycarboxylic acid agent or utilized independently for maximum effect.
2. This product can be employed alone (although typically not used solo) or in conjunction with other components. By blending with water-reducing and set-retarding mother liquors, it effectively mitigates concrete slump loss. Alternatively, it can be compounded with functional additives to produce admixtures with enhanced retarder, early strength, antifreeze, and pumping properties. Application methods and conditions should be meticulously determined through rigorous testing and compounding technology.
3. Compatible with various admixtures like early strength agents, air entrainment agents, and retarders. It is essential to conduct tests prior to use. Avoid combining with naphthalene-based water reducers.
4. When active admixtures such as fly ash and slag are part of the concrete mix, calculate the water-reducer dosage based on the total cementitious materials for optimal results.
