JS-109 is a revolutionary advancement in slump-preserving polycarboxylic acid water reducers, ingeniously crafted by Shandong Gaoqiang New Material Technology Co., Ltd. Its exceptional design ensures a significant reduction in concrete slump loss, making it highly effective as a high water-reducing polycarboxylic acid reducer. This versatile product finds extensive applications across a variety of concrete formulations, including pumping concrete, super-fluid self-compacting, high-strength, high-performance, and commercial concrete projects.
At the core of JS-109 lies an innovative molecular structure, ingeniously incorporating active groups such as ester and amide groups, resulting in a polycarboxylic acid superplasticizer with unparalleled slump retention abilities. Within the alkaline environment of concrete, these ester groups undergo a gradual hydrolysis into carboxylic acid groups, which meticulously adsorb onto cement particles' surfaces, delivering an outstanding slow-release slump protection mechanism.
In the alkaline milieu of concrete, the dynamic reactive groups embedded in this product's molecular structure initiate a controlled release of dispersing-effect groups. This strategic release serves to perpetually disperse cement particles, thereby effectively curbing the loss of slump in concrete.
(1) Boasting a substantial slump retention capacity, JS-109 permits a retention of more than 80% of the original slump of fresh concrete after one hour, adeptly addressing the common issue of rapid concrete slump loss. after 1 hour, which can effectively solve the problem of rapid concrete slump loss.
(2) Post-application, concrete exhibits stellar performance with remarkable workability, superb hardening properties, and exceptional durability.
(3) Demonstrating broad adaptability, it is compatible with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and a variety of admixtures.
(4) Environmentally conscious: JS-109 is produced sustainably, ensuring no three waste products are generated in the process.

(1) This versatile product is perfect for crafting a spectrum of concrete types including early-strength, retarded, precast, cast-in-place, large flow, self-compacting, mass, high-performance, and fair-faced concrete. It is especially suitable for diverse industrial and civil construction projects, ready-mixed and cast-in-situ concrete, and is particularly advantageous for low-grade commercial concrete.
(2) JS-109 is extensively utilized in monumental national and key infrastructural projects such as high-speed railways, nuclear power facilities, water conservancy and hydropower projects, subways, large bridges, expressways, harbors, and wharves, illustrating its indispensable role in pivotal constructions.
(3) It is ideally suited for integration into a variety of industrial and civil construction projects as well as commercial concrete mixing plants.
1. The recommended dosage is 0.6%~1.2% of the total cementitious material weight, with the optimal amount determined through experimentation based on specific engineering materials and characteristics. Suitable for blending with high water reducing polycarboxylic acid water reducing agents or individual use.
2. JS-109 can be utilized alone (though generally not recommended) or combined with water-reducing mother liquors and set retarding mother liquors to mitigate concrete slump loss. It can also be compounded with functional additives for admixtures that provide retarder, early strength, antifreeze, or pumping functionalities. Application methods and conditions should be determined via thorough testing and compounding technology.
3. Compatible with various admixtures like early strength agents, air entrainment agents, and retarders; however, testing is required before use. Avoid mixing with naphthalene series water reducers.
4. In scenarios where active admixtures such as fly ash and slag are part of the concrete mix, the calculation for the water-reducing agent should encompass the total amount of cementing materials.
Package: Conveniently available in 220kgs/drum, 24.5 tons/Flexitank, 1000kg/IBC, or customized packaging upon request to suit your specific requirements.
Storage: For optimal efficacy, store in a ventilated, dry warehouse at temperatures ranging from 2-35ºC. Ensure the packaging remains sealed and intact for a shelf life extending up to one year. Protect the product vigilantly from direct sunlight exposure and freezing temperatures.
