BT-303, the latest breakthrough in polycarboxylic acid water reducers, designed exclusively by Shandong Gaoqiang New Material Technology Co., Ltd. This cutting-edge solution excels at significantly combatting concrete slump loss. BT-303 is the ideal choice for high water-reducing polycarboxylic acid reducers, showcasing versatility across a spectrum of applications, including pumping concrete, super-fluid self-compacting concrete, as well as high-strength and high-performance concrete. Whether you're working with commercial concrete or other demanding projects, BT-303 is engineered to deliver exceptional results.
BT-303's innovative molecular design incorporates active groups such as ester and amide groups, crafting a polycarboxylic acid superplasticizer with superior slump retention properties. Within the alkaline environment of concrete, the ester groups undergo gradual hydrolysis, transforming into carboxylic acid groups that adhere to cement particles. This process facilitates a remarkable slow-release slump protection effect, ensuring consistent concrete quality.
In the alkaline milieu of concrete, BT-303's reactive molecular groups slowly liberate dispersing agents, ensuring the continuous dispersion of cement, and effectively mitigating concrete slump loss. This innovative mechanism preserves the concrete's optimal state, enhancing longevity and performance.
(1) Exceptional slump retention: A remarkable capability to maintain over 80% of the original slump value of fresh concrete even after an hour, decisively addressing rapid slump loss issues. This groundbreaking feature effectively tackles the challenge of concrete's swift slump reduction, ensuring enduring workability.
(2) Optimal concrete performance: Fresh concrete benefits from outstanding workability, with superior hardening and durability post-application, making it a prime choice for quality construction.
(3) Broad compatibility: Seamlessly compatible with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and various admixtures, BT-303 offers diverse adaptability across construction needs.
(4) Environmentally conscious: Embrace green construction with BT-303, a product free from 'three wastes' during production, supporting sustainable development initiatives.

(1) Perfect for producing early-strength, retarded, precast, cast-in-place, large flow, self-compacting, mass, high-performance, and fair-faced concrete. BT-303 is quintessential for industrial and civil buildings, particularly low-grade commercial concrete, ensuring a robust performance.
(2) Widely applicable to significant national projects such as high-speed railways, nuclear power facilities, water conservancy and hydropower projects, subways, large bridges, expressways, harbors, and wharfs, ensuring excellence in every structure.
(3) Ideal for diverse industrial and civil construction projects and commercial concrete mixing plants, ensuring consistent quality and performance.
1. The standard dosage ranges from 0.6% to 1.2% based on the total cementitious materials. Determine the optimal dosage through experimental evaluation according to specific engineering materials and characteristics. BT-303 can be used in conjunction with high water-reducing polycarboxylic acid water-reducing agents or independently for maximum effect.
2. While typically not used alone, BT-303 can be combined with water-reducing and set retarding mother liquors to minimize slump loss. Alternatively, it can be mixed with functional aids to produce admixtures featuring retardation, early strength, antifreeze, or pumping capabilities. Customize application methods and conditions through thorough testing and compounding technology for best results.
3. BT-303 is compatible with various admixtures like early strength agents, air entrainment agents, and retarders, but it is vital to conduct tests before use. Avoid combining it with naphthalene series water reducers to maintain optimal performance.
4. When incorporating active admixtures such as fly ash and slag into the concrete mix, calculate the water-reducing agent dosage based on the total amount of cementitious materials to ensure accurate formulation.
Packaging options: Secure your BT-303 in 220-kilogram drums, 23.5 tons in Flexitanks, or 1100-kilogram IBCs. Custom packaging solutions are available upon request, ensuring your product arrives safely and efficiently.
Storage: Ensure your BT-303 Superplasticizer remains in optimal condition by storing it in a ventilated and dry warehouse at temperatures between 2-35 degrees. Keep the product packaged securely and sealed to maintain its efficacy throughout its one-year shelf life. Protect from direct sunlight and freezing conditions to ensure maximum performance.
BT-303 represents the new frontier in slump-preserving polycarboxylic acid water reducers, independently developed to significantly mitigate concrete slump loss. Ideal for high water-reducing applications, it brings unparalleled benefits to pumping concrete, super-fluid self-compacting, high-strength, and high-performance concrete, including commercial varieties.
In the alkaline environment of concrete, reactive groups within the molecular framework of our product release dispersing agents over time, perpetuating cement dispersion and effectively curtailing concrete slump loss.
