Introducing the BT-303, a revolutionary polycarboxylic acid water reducer independently crafted by Shandong Gaoqiang New Material Technology Co., Ltd. This advanced formulation is expertly designed to dramatically curb concrete slump loss, making it indispensable for high water-reducing polycarboxylic applications. Perfect for pumping concrete, super-fluid self-compacting, high-strength, high-performance, and commercial-grade concrete, BT-303 sets a new standard in concrete mix innovation.
Harnessing the power of cutting-edge chemistry, this product integrates active groups such as ester and amide groups into its molecular structure. This results in a polycarboxylic acid superplasticizer with unparalleled slump retention capabilities. When exposed to the alkaline environment of concrete, these ester groups gradually transform into carboxylic acid groups that adeptly adhere to cement particles. This transformation ensures a consistent and effective slow-release slump protection effect, elevating concrete performance to new heights.
Within the alkaline milieu of concrete, the ingenious reactive groups within this product's molecular framework release dispersal groups progressively, which continue to disperse cement particles efficiently. This seamless action prevents concrete from losing its vital slump, ensuring optimal performance and durability.
(1) Boasting an impressive slump retention value, the product ensures that the slump remains at more than 80% of fresh concrete's original value after 1 hour, providing a robust solution to rapid slump loss.
(2) After application, the concrete exhibits excellent performance. Freshly mixed, it offers superior workability and, once hardened, delivers exceptional durability and resilience.
(3) Versatile Adaptability: The product shows excellent compatibility with various cements, including Portland, ordinary Portland, slag silicate, fly ash, pozzolan cements, and numerous other admixtures, ensuring wide-ranging utility.
(4) Eco-Conscious: Environmentally friendly, this product is manufactured without generating 'three wastes,' contributing to sustainable building practices.

(1) Ideal for crafting early-strength, retarded, precast, cast-in-place, large flow, self-compacting, mass, high-performance, and fair-faced concretes. It is especially suited for ready-mixed and cast-in-situ concrete, including various industrial and civil construction needs, and is perfect for low-grade commercial concrete.
(2) Its versatility extends to national and key infrastructure projects, including high-speed railways, nuclear power, water conservancy, hydropower projects, subways, large bridges, expressways, harbors, and wharfs, ensuring robust and reliable performance across diverse applications.
(3) Perfectly suited for a wide array of industrial and civil construction projects and commercial concrete mixing plants, making it an essential addition to any construction arsenal.
1. The recommended dosage ranges between 0.6% and 1.2% relative to the total cementitious content. Optimal usage should be verified through trials, tailored to specific engineering materials and project characteristics. It can be utilized alone or in combination with high water-reducing polycarboxylic agents for best results.
2. Versatility in Use: While this product can occasionally be used independently, it is typically combined with water-reducing and set-retarding agents to minimize slump loss. Additionally, it can be paired with functional additives for enhanced properties like retarding, early strength, antifreeze, and pumping. Application methods and conditions should be defined through tailored testing and formulating techniques.
3. This product synergizes effectively with various admixtures, such as early strength agents, air entrainment, and retarders. However, it should be tested prior to use and must not be mixed with naphthalene series water reducers.
4. When employing active admixtures like fly ash and slag within the concrete composition, calculate the water-reducing agent proportion based on the total cementitious material content for optimal effectiveness.
Package: Offering flexible packaging options to suit your needs, including 220kgs/drum, 23.5 tons/Flexitank, and 1100kg/IBC, or customized upon request, ensuring efficient and convenient delivery.
