Introducing the cutting-edge JS-109 Polycarboxylate Superplasticizer Liquid, meticulously developed by Shandong Gaoqiang New Material Technology Co., Ltd. This advanced slump-preserving polycarboxylic acid water reducer is designed to substantially mitigate concrete slump loss, ensuring superior performance in high water-reduction applications. Seamlessly adaptable, it excels in pumping concrete, super-fluid self-compacting, high-strength and high-performance concrete, as well as commercial concrete, making it an indispensable solution for your construction needs.
Harnessing the power of modern chemistry, this product incorporates active ester and amide groups within its molecular structure to create a polycarboxylic acid superplasticizer with exceptional slump retention abilities. Under concrete's alkaline conditions, these ester groups undergo a gradual transformation into carboxylic acid groups, which then adeptly adhere to cement particles. This adherence instigates a slow-release mechanism, delivering sustained and effective slump protection.
Within the alkaline environment of concrete, the active groups embedded in this product's molecular structure methodically release dispersing agents. These agents continue to effectively disperse cement, thus ensuring a long-lasting slump-preservation effect, invaluable for maintaining concrete integrity over time.
(1) Boasting an impressive slump retention value, it ensures the maintenance of over 80% of initial slump in fresh concrete even after one hour, deftly addressing the challenge of rapid slump loss. This feature effectively tackles the pressing issue of rapid concrete slump loss, keeping your projects on track with unwavering precision and efficiency.
(2) Impressive performance: Post-application, concrete exhibits remarkable workability, along with superior hardening and long-lasting durability.
(3) Versatile adaptability: It seamlessly integrates with a range of cements, including Portland, ordinary Portland, slag silicate, fly ash, pozzolan, and various admixtures.
(4) Eco-friendly and sustainable, the production process generates no three waste products, ensuring minimal environmental impact.

(1) An ideal choice for crafting early-strength, retarded, precast, cast-in-place, large-flow, self-compacting, mass, high-performance, and fair-faced concrete. It is particularly beneficial for ready-mixed and cast-in-situ concrete used in industrial and civil buildings, especially suited for low-grade commercial concrete.
(2) Its versatility extends to national and key infrastructure projects, including high-speed railways, nuclear power, water conservancy, hydropower projects, subways, large bridges, expressways, harbors, and wharfs.
(3) Suitable for diverse industrial and civil construction projects and commercial concrete mixing plants, delivering unparalleled results across various applications.
1. Typically utilized at a dosage of 0.6% to 1.2% of total cementitious materials, optimal usage is best determined through experimentation based on specific project materials and requirements. This product is effective when used alone or in synergy with other high water-reducing polycarboxylic agents.
2. Although generally used in combination, this product can be singularly applied (though less common) or blended with water-reducing and set-retarding mother liquors to mitigate concrete slump loss. It may also be compounded with functional aids for admixtures featuring retarder, early strength, antifreeze, and pumping properties, with application methods tailored through testing and compounding technology.
3. Compatible with other admixtures like early strength agents, air-entraining agents, and retarders, it is crucial to conduct tests prior to use and avoid combining with naphthalene series water reducers for optimal results.
4. When incorporating active admixtures such as fly ash and slag in concrete, calculate the water-reducing agent percentage based on the total amount of cementitious materials for precise and effective application.
Package: Conveniently available in 220 kg drums, 24.5 tons Flexitanks, 1000 kg IBCs, or customized packaging options to suit your specific requirements.
Storage: To maintain its premium quality and effectiveness, the JS-109 Polycarboxylate Superplasticizer Liquid should be stored in a well-ventilated, dry warehouse with temperatures ranging from 2-35ºC. Ensure that the packaging remains intact and unopened. This product boasts a shelf life of one year. It is crucial to protect it from direct sunlight and freezing to preserve its optimal performance.
BT-303 represents a cutting-edge, independently developed slump-preserving polycarboxylic acid water reducer by our company. Engineered to effectively curb slump loss in concrete, it is ideally suited for high water-reducing applications. This versatile product is perfect for use in pumping concrete, super-fluid self-compacting, high-strength, and high-performance concrete, as well as commercial concrete projects.
In the alkaline milieu of concrete, the reactive groups in the product's molecular structure release dispersing groups gradually. This mechanism aids in the continual dispersion of cement, effectively preventing slump loss and preserving the concrete's desired state.
(1) The product exhibits a remarkable slump retention capacity, maintaining over 80% of the fresh concrete's slump after one hour, effectively addressing rapid slump loss challenges. This feature ensures that the slump of the fresh concrete remains above 80% after an hour, effectively solving issues related to rapid slump loss.
(2) The use of this product enhances the concrete's performance, offering excellent workability while fresh, coupled with superior hardening and durability post-application.
(3) It boasts broad adaptability, making it compatible with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and various admixtures.
