Presenting BT-303, the zenith of polycarboxylic acid water reducers, meticulously developed by Shandong Gaoqiang New Material Technology Co., Ltd. This state-of-the-art formulation is crafted to dramatically reduce slump loss in concrete, rendering it the perfect solution for high water-reducing requirements. BT-303 excels in a multitude of applications, ranging from pumping concrete and ultra-fluid self-compacting mixtures to high-strength and high-performance concrete - precisely engineered to meet the rigorous demands of commercial concrete endeavors.
BT-303 is distinguished by its groundbreaking molecular architecture, featuring active ester and amide groups. This unique composition gives rise to a polycarboxylic acid superplasticizer celebrated for its slump retention prowess. Within the alkaline nature of concrete, ester groups undergo hydrolysis into carboxylic acid, adsorbing onto cement particles to provide a prolonged, slow-release slump defense, ensuring enduring workability.
In concrete's alkaline milieu, the product's reactive molecular groups progressively release dispersive elements, maintaining cement dispersion and effectively counteracting premature slump loss. The outcome is a precisely managed concrete consistency that upholds high-performance benchmarks.
(1) Remarkable slump retention: Retains more than 80% of initial slump after 1 hour, effortlessly addressing rapid slump loss challenges.Fresh concrete sustains superior workability, while the hardened form offers outstanding durability and resilience.
(2) Exceptional Usage Excellence: The workability, hardening, and durability of concrete are all significantly enhanced with the inclusion of this admixture.
(3) Unparalleled Adaptability: Harmonizes perfectly with Portland, ordinary Portland, slag silicate, fly ash, pozzolan cements, and a variety of admixtures, demonstrating its versatility across diverse applications.
(4) Environmentally Responsible: Manufactured without producing waste, making it a sustainable choice for eco-friendly construction.

(1) Versatile concrete preparation: From early-strength to self-compacting, precast to large flow, BT-303 showcases its excellence across a wide range of concrete types, especially ideal for low-grade commercial applications.
(2) Ideal for major projects: High-speed railways, nuclear power plants, water conservancy projects, subways, bridges, expressways, harbors, and wharfs all gain from its superior performance characteristics.
(3) Universally suitable: Fits various industrial, civil construction, and commercial concrete mixing plants, consistently ensuring quality and performance.
1. Recommended dosage: 0.6%~1.2% of the total cementitious material. Optimal usage should be determined through testing, whether employed independently or in combination with high water-reducing agents.
2. Versatile application: BT-303 can be utilized alone or mixed with water-reducing mother liquor and retarding agents to minimize slump loss, or combined with functional aids for enhanced retarder, early strength, antifreeze, and pumping capabilities. Testing is recommended to customize application methods.
3. Versatile compatibility: Suitable for use with early strength agents, air entrainment agents, and retarders, contingent on pre-use testing. Should not be used in conjunction with naphthalene-based reducers.
4. When employing active admixtures like fly ash or slag, calculate the water-reducing agent amount based on the total cementitious materials for optimal performance results.
Packaging options: Available in 220kgs/drum, 23.5 tons/Flexitank, or 1100kg/IBC, customized to your specific needs.
