Introducing BT-303, a cutting-edge, next-generation slump-preserving polycarboxylic acid water reducer, meticulously crafted by Shandong Gaoqiang New Material Technology Co., Ltd. This advanced formulation dramatically minimizes slump loss in concrete, making it an ideal choice for high water-reducing polycarboxylic acid applications. Discover its versatility when used in pumping concrete, super-fluid self-compacting systems, high-strength and high-performance concrete, as well as commercial concrete solutions.
Our product's molecular architecture ingeniously incorporates active groups such as ester and amide groups, creating a polycarboxylic acid superplasticizer with exceptional slump retention abilities. In the alkaline environment of concrete, these ester groups systematically hydrolyze into carboxylic acid groups, which adhere to the cement particles' surface, providing a sustained slow-release slump protection mechanism.
Within the alkaline milieu of concrete, the reactive groups embedded in this product's molecular framework gradually unleash dispersing groups, effectively dispersing the cement. This action successfully curtails concrete slump loss over time, ensuring prolonged workability and consistency.
(1) Exceptional slump retention capability, with a retention value reaching over 80% of the initial slump of fresh concrete after 1 hour, adeptly addressing the issue of rapid concrete slump decline.
(2) Outstanding post-application concrete performance. The fresh concrete exhibits superior workability, alongside excellent hardening and long-lasting durability.
(3) Broad adaptability across diverse types of cement, including Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and various admixtures.
(4) Environmentally conscious and sustainable, the production process generates no waste products, aligning with green manufacturing principles.

(1) Perfectly suited for crafting early-strength concrete, retarded concrete, precast concrete, cast-in-place concrete, high-flow concrete, self-compacting concrete, mass concrete, high-performance concrete, and fair-faced concrete. It is particularly advantageous for various industrial and civil buildings, specifically low-grade commercial concrete.
(2) Ideal for use in prestigious national and pivotal infrastructure projects like high-speed railways, nuclear power facilities, water conservancy and hydropower initiatives, subways, large-scale bridges, expressways, harbors, and wharfs.
(3) Extensively applicable across a wide range of industries and civil construction projects, including commercial concrete mixing plants.
1. The recommended dosage ranges from 0.6% to 1.2% (based on the total cementitious materials weight). Determining the ideal dosage necessitates experimentation considering material specifics and project characteristics. Suitable for sole use or in combination with high water-reducing polycarboxylic acid water reducing agents.
2. This product may be utilized solo, though typically not advised. It can be blended with water-reducing mother liquor and set retarding mother liquor to mitigate concrete slump loss, or combined with functional aids to create admixtures offering retarder/early strength/antifreeze/pumping functionalities. Application methods and conditions should be verified with testing and compounding technology.
3. Compatible with other admixtures, such as early strength agents, air entrainment agents, and retarders; testing is recommended before use. Not to be mixed with naphthalene series water reducers.
4. When active admixtures like fly ash and slag are included in the concrete mix, compute the water-reducing agent quantity based on the total cementitious material content.
Package: Available in 220kgs/drum, 23.5 tons/Flexitank, 1100kg/IBC, or customized upon request, ensuring convenient and flexible delivery solutions tailored to your needs.
