Introducing BT-303, a marvel of modern engineering by Shandong Gaoqiang New Material Technology Co., Ltd. This top-tier polycarboxylic acid water reducer is designed to dramatically minimize concrete slump loss, making it the ultimate solution for high water-reducing needs. BT-303 excels across various applications, from pumping concrete and ultra-fluid self-compacting mixtures to robust high-strength concrete, meeting the rigorous demands of commercial projects with precision.
BT-303 is distinguished by its advanced molecular structure, featuring active ester and amide groups. This innovative design results in a polycarboxylic acid superplasticizer celebrated for its exceptional slump retention. When integrated into concrete's alkaline environment, ester groups undergo hydrolysis to form carboxylic acid, which adsorbs onto cement particles. This process ensures a prolonged, gradual slump protection, maintaining workability over extended periods.
In concrete's alkaline milieu, BT-303's reactive molecular groups release dispersive elements steadily, preserving cement dispersion and effectively counteracting premature slump loss. This ensures meticulously controlled concrete consistency that aligns with high-performance benchmarks.
(1) Unrivaled Slump Retention: BT-303 retains over 80% of the initial slump for an hour, effortlessly overcoming rapid slump loss challenges.Fresh concrete maintains optimal workability, while the cured state delivers superior durability and robustness.
(2) Exceptional Usability: Enhances the workability, hardening, and durability of concrete remarkably post-admixture.
(3) Extraordinary Versatility: Compatible with Portland, ordinary Portland, slag silicate, fly ash, pozzolan cements, and various admixtures, illustrating its adaptability.
(4) Eco-Friendly Production: Manufactured without waste, making it an environmentally friendly choice for sustainable construction projects.

(1) Versatile Concrete Solutions: From early-strength to self-compacting, precast to high-flow, BT-303 excels across a range of concrete types, especially suited for low-grade commercial applications.
(2) Ideal for Landmark Projects: High-speed railways, nuclear power stations, water conservancy works, subways, bridges, expressways, harbors, and wharfs benefit from its outstanding performance.
(3) Universally Applicable: Suitable for diverse industrial, civil construction, and commercial concrete mixing plants, ensuring consistent quality and reliable performance.
1. Recommended Dosage: 0.6%~1.2% of the total cementitious material. Determine the optimal dosage through testing, whether using BT-303 alone or in combination with high water-reducing agents.
2. Flexible Application: BT-303 can be applied solo or in conjunction with water-reducing mother liquor and retarding agents to minimize slump loss, or combined with functional aids for retardation, early strength, antifreeze, and pumping efficiencies. Testing is recommended to customize application methods.
3. Broad Compatibility: Can be used with early strength agents, air entrainment agents, and retarders, subject to pre-use testing. Avoid using with naphthalene-based reducers.
4. When using active admixtures like fly ash or slag, calculate the water-reducing agent amount based on the total cementitious materials to achieve optimal results.
Packaging Choices: Available in 220kgs/drum, 23.5 tons/Flexitank, or 1100kg/IBC, adaptable to your specific requirements.
