Introducing BT-303, a groundbreaking innovation in polycarboxylic acid water reducers, meticulously developed by Shandong Gaoqiang New Material Technology Co., Ltd. This state-of-the-art solution is expertly designed to dramatically minimize the slump loss of concrete, making it the premier choice for high water-reducing applications. BT-303 excels in various uses, including pumping concrete, super-fluid self-compacting mixtures, and high-strength, high-performance concrete, perfectly crafted to meet the demands of commercial concrete projects.
BT-303 distinguishes itself with an avant-garde molecular structure, enriched with active ester and amide groups. This sophisticated design creates a polycarboxylic acid superplasticizer celebrated for its superior slump retention capabilities. Within concrete's alkaline environment, the ester groups undergo hydrolysis to form carboxylic acid, which adsorbs onto cement particles, providing a sustained, slow-release slump protection that guarantees extended workability.
In the alkaline environment of concrete, the molecular reactive groups of the product gradually release dispersive elements, ensuring consistent cement dispersion and effectively preventing premature slump loss. This results in a finely-tuned concrete consistency that meets the highest performance standards.
(1) Remarkable slump retention: Retains over 80% of initial slump after 1 hour, effortlessly overcoming rapid slump loss challenges.Fresh concrete maintains excellent workability, while in its hardened state it provides outstanding durability and resilience.
(2) Excellence in Usage: The workability, hardening, and durability of concrete are all significantly enhanced post-admixture.
(3) Unrivaled Adaptability: Fully compatible with Portland, ordinary Portland, slag silicate, fly ash, pozzolan cements, and a multitude of admixtures, demonstrating its versatility.
(4) Eco-Conscious Choice: Produced without waste generation, making it a sustainable option for green construction.

(1) Versatile Concrete Preparation: From early-strength to self-compacting, precast to large flow, BT-303 excels across a wide range of concrete types, particularly suited for low-grade commercial applications.
(2) Perfect for Landmark Projects: High-speed railways, nuclear power facilities, water conservancy projects, subways, bridges, expressways, harbors, and wharfs all greatly benefit from its exceptional performance.
(3) Suitable for All Applications: Ideal for various industrial, civil construction, and commercial concrete mixing plants, delivering consistent quality and performance.
1. Recommended Dosage: Utilize 0.6%~1.2% of the total cementitious material. Optimal usage should be determined through testing, whether employed alone or in combination with high water-reducing agents.
2. Flexible Application: BT-303 can be used individually or blended with water-reducing mother liquor and retarding agents to minimize slump loss. It can also be combined with functional aids for retarder, early strength, antifreeze, and pumping capabilities. Testing is recommended to tailor application methods.
3. Comprehensive Compatibility: Compatible with early strength agents, air entrainment agents, and retarders, subject to pre-use testing. Avoid combining with naphthalene-based reducers.
4. For optimal results, when using active admixtures like fly ash or slag, calculate the water-reducing agent amount based on the total cementitious materials.
Packaging Options: Offered in 220kgs/drum, 23.5 tons/Flexitank, or 1100kg/IBC, customized to meet your specific requirements.
