Introducing BT-303, a groundbreaking polycarboxylic acid water reducer meticulously developed by Shandong Gaoqiang New Material Technology Co., Ltd. This innovative solution is engineered to drastically reduce slump loss in concrete, positioning it as the ultimate choice for high-efficiency water-reducing applications. BT-303 is expertly designed for a wide array of uses, including pumping concrete, ultra-fluid self-compacting mixtures, and robust high-strength, high-performance concrete-perfectly engineered for the rigorous demands of commercial concrete projects.
BT-303 is distinguished by its pioneering molecular structure, which incorporates active ester and amide groups. This sophisticated design results in a polycarboxylic acid superplasticizer celebrated for its exceptional slump retention abilities. In the alkaline realm of concrete, ester groups metamorphose into carboxylic acid, adhering to cement particles for a prolonged, controlled slump protection, ensuring enduring workability.
Amidst the alkaline environment of concrete, the product's reactive molecular groups steadily release dispersive elements, maintaining cement particle separation and effectively countering early slump loss. The outcome is a finely-tuned concrete consistency that aligns with demanding high-performance standards.
(1) Exceptional slump retention: Maintains over 80% of the initial slump after one hour, effortlessly addressing rapid slump loss issues.Fresh concrete retains outstanding workability, while the hardened material boasts unparalleled durability and resilience.
(2) Superior Usage: Workability, hardening, and durability of concrete are remarkably enhanced after admixture integration.
(3) Outstanding Compatibility: Harmonizes seamlessly with Portland, regular Portland, slag silicate, fly ash, pozzolan cements, and various other admixtures, highlighting its versatility.
(4) Eco-Friendly: Manufactured without waste production, making it an environmentally responsible choice for sustainable construction.

(1) Versatile concrete readiness: From early-strength to self-compacting, precast to extensive flow, BT-303 excels in a variety of concrete formulations, particularly suited for low-grade commercial use.
(2) Ideal for significant projects: High-speed railways, nuclear power facilities, water conservancy, subways, bridges, expressways, harbors, and wharfs significantly benefit from its stellar performance.
(3) Universal applicability: Suitable for an assortment of industrial, civil construction, and commercial concrete mixing plants, ensuring consistency in quality and outcomes.
1. Recommended dosage: 0.6%~1.2% of the total cementitious material. Optimal usage should be determined via testing, whether used independently or combined with other high water-reducing agents.
2. Versatile application: BT-303 can be utilized independently or mixed with water-reducing mother liquor and retarding agents to minimize slump loss, or combined with specialized aids for retarder, early strength, antifreeze, and pumping functionalities. Testing is advised to customize application methods.
3. Comprehensive compatibility: Employable with early strength agents, air entrainment agents, and retarders, pending pre-use testing. Not suitable for combination with naphthalene-based reducers.
4. When utilizing active admixtures like fly ash or slag, calculate the required amount of water-reducing agent based on the total cementitious materials for best results.
Packaging options: Offered in 220kgs/drum, 23.5 tons/Flexitank, or 1100kg/IBC, customizable to your specific needs.
