JS-109, meticulously crafted by Shandong Gaoqiang New Material Technology Co., Ltd, represents a groundbreaking advancement in slump-preserving polycarboxylic acid water reducers. Its remarkable ability to significantly curb slump loss in concrete makes it the quintessential choice for high-performance applications. Whether in pumping concrete, super-fluid self-compacting mixes, or high-strength commercial concretes, JS-109 stands as a versatile, indispensable solution.
Harnessing the power of an innovative molecular structure, JS-109 introduces active ester and amide groups to create a polycarboxylic acid superplasticizer with superior slump retention. In the concrete's alkaline setting, ester groups strategically hydrolyze into carboxylic acid groups, adhering to cement particles and providing a gradual, effective slow-release slump protection.
Through its unique molecular design, JS-109's reactive groups slowly emit dispersing agents in alkaline concrete environments, perpetuating cement dispersion and effectively maintaining concrete slump integrity over time.
(1) The impressive slump retention capability ensures that over 80% of fresh concrete's initial slump is preserved even after an hour, addressing rapid slump loss concerns efficiently. This assurance of sustained workability translates into a seamless construction process, optimizing both fresh concrete usability and eventual hardening attributes.
(2) Post-application, concrete showcases exemplary performance, from seamless workability during pouring to enhanced hardening and enduring durability.
(3) Its adaptability is unmatched, accommodating various cement types including Portland, slag silicate, and pozzolan cements, as well as numerous admixtures.
(4) Designed with environmental consciousness, JS-109's production yields no waste byproducts, making it a green, sustainable choice for modern construction needs.

(1) Ideal for crafting a variety of concretes-early-strength, retarded, precast, cast-in-place, self-compacting, mass, high-performance, and fair-faced-JS-109 is especially suited for low-grade commercial concrete in both industrial and civil structures.
(2) Its application extends across national and monumental projects such as high-speed railways, nuclear facilities, water conservancy, hydropower initiatives, subways, large bridges, expressways, harbors, and docks.
(3) Equally effective in diverse industrial and civil construction contexts, JS-109 enhances the operations of commercial concrete mixing plants with its superior properties.
1. A recommended dosage between 0.6% and 1.2% of total cementitious materials should be established through experimentation. JS-109 can be synergistically combined with high water-reducing agents or deployed independently for optimal results.
2. While JS-109 can be used solo, it achieves unparalleled synergy when blended with water-reducing and set-retarding mother liquors to mitigate concrete slump loss. For tailored admixtures featuring retarder, early strength, antifreeze, or pumping functionalities, testing and precise compounding are essential.
3. Compatible with a variety of admixtures like early strength agents and retarders, JS-109 should undergo pre-use testing. Avoid combining with naphthalene series water reducers to maintain integrity.
4. When fly ash or slag feature in the concrete mix, calculate the water-reducing agent amount based on the total cementitious content for optimized performance.
Package: Choose from 220kgs/drum, 24.5 tons/Flexitank, or 1000kg/IBC, with custom options available to meet specific delivery needs.
Storage: Ensure that the product is stored in a well-ventilated, dry warehouse maintaining a temperature range of 2-35ºC. Keep the packaging sealed for optimal preservation; under these conditions, the shelf life extends to one year. Protect the product vigilantly from direct sunlight and freezing.
Introducing BT-303, an innovative slump-preserving polycarboxylic acid water reducer independently crafted by our company. This advanced formula effectively curtails concrete slump loss, ideal for high-efficiency water-reducing applications. Its versatility makes it suitable for pumping concrete, super-fluid self-compacting, high-strength, and high-performance concrete, as well as commercial concrete.
In concrete's alkaline environment, the active groups in the product's molecular structure slowly release dispersive groups, maintaining continued cement dispersion, thus effectively preventing concrete slump loss.
(1) Exceptional slump retention capacity, maintaining over 80% of the initial slump even after one hour, decisively addressing rapid slump loss issues. of the fresh concrete after 1 hour, which can effectively solve the problem of rapid concrete slump loss.
(2) Outstanding post-application performance. Fresh concrete exhibits superior workability, hardens excellently, and boasts remarkable durability.
(3) Extensive adaptability to a variety of cements including Portland, ordinary Portland, slag silicate, fly ash, pozzolan, and a range of admixtures.
(4) Environmentally conscious production with zero waste products, championing green manufacturing processes.

(1) Perfectly tailored for crafting a wide array of concrete types including early-strength, retarded, precast, cast-in-place, large flow, self-compacting, mass, high-performance, and elegant fair-faced concrete. Ideal for both industrial and civil projects, it excels in ready-mixed and cast-in-situ concrete applications, with a particular finesse for low-grade commercial concrete.
(2) Widely embraced in paramount national and key projects such as high-speed railways, nuclear power facilities, water conservancy and hydropower ventures, subways, monumental bridges, expressways, harbors, and wharfs, this superplasticizer is a versatile powerhouse.
(3) Versatile in its application, it is suited for all kinds of industrial and civil construction alongside commercial concrete mixing plants, offering unparalleled adaptability.
1. Typically utilized at a dosage of 0.6%~1.2% (based on the total cementitious material), the optimal dosage is best determined through experimental testing, aligned with the specific engineering materials and their distinct characteristics. Whether combined with a high water-reducing polycarboxylic acid agent or used independently, its application is seamless.
2. While this product can be used individually-though generally not recommended-it shines when combined with water-reducing and set-retarding mother liquors to minimize concrete slump loss. Further, it can be compounded with functional aids to create admixtures with retarding, early strength, antifreeze, and pumping capabilities. Testing and precise compounding technology are key to determining the optimal application method and conditions.
