BT-303 is a cutting-edge, next-generation polycarboxylic acid water reducer, meticulously crafted by Shandong Gaoqiang New Material Technology Co., Ltd. This revolutionary product dramatically curtails the slump loss of concrete, ensuring superior performance. Perfectly tailored for high water-reducing scenarios, BT-303 is an exemplary choice for use in pumping concrete, super-fluid self-compacting, high-strength, high-performance, and commercial concrete applications.
The ingenious molecular structure of BT-303 incorporates dynamic active groups such as ester and amide groups, culminating in a polycarboxylic acid superplasticizer that boasts extraordinary slump retention properties. In the alkaline environment of concrete, the ester groups undergo gradual hydrolysis into carboxylic acid groups, which then affix to the cement particles' surface, offering a remarkable slow-release slump protection mechanism.
In the alkaline milieu of concrete, the reactive groups within BT-303's molecular framework gradually liberate dispersing effect groups, sustaining the dispersion of cement particles. This innovative process effectively mitigates the detrimental loss of concrete slump, sustaining a robust and cohesive mixture.
(1) Outstanding slump retention: The product ensures a slump retention value so high that it preserves over 80% of the fresh concrete's initial slump after one hour. This feature deftly addresses the challenge of swift concrete slump loss.
(2) Exemplary concrete performance: Post-application, the fresh concrete demonstrates exceptional workability, hardening, and durability, ensuring a long-lasting and reliable structure.
(3) Versatile adaptability: BT-303 displays impressive compatibility with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and diverse admixtures, making it an adaptable ally for various formulations.
(4) Eco-friendly and sustainable: The production process of BT-303 is green and environmentally friendly, with zero waste products, aligning with modern sustainability practices.

(1) Ideally suited for crafting early-strength, retarded, precast, cast-in-place, large flow, self-compacting, mass, high-performance, and fair-faced concrete. It is especially beneficial for various industrial and civil buildings, ready-mixed and cast-in-situ concrete, and is perfectly tailored for low-grade commercial concrete scenarios.
(2) An indispensable choice for national and key infrastructure projects, BT-303 excels in high-speed railways, nuclear power, water conservancy, hydropower projects, subways, large bridges, expressways, harbors, and wharfs.
(3) Versatile enough to serve a wide range of industrial and civil construction applications, as well as commercial concrete mixing plants, making it a universal solution for diverse construction needs.
1. The typical dosage ranges from 0.6% to 1.2% of the total cementitious material weight. The optimal dosage should be ascertained through experimental evaluation based on specific engineering materials and characteristics. BT-303 can either be used in conjunction with a high water-reducing polycarboxylic acid water-reducing agent or independently.
2. While BT-303 can be used solo, it is usually recommended to blend it with a water-reducing mother liquor and set retarding mother liquor to curtail concrete slump loss. Additionally, it can be compounded with functional aids to develop admixtures with retarder, early strength, antifreeze, or pumping capabilities. Employ testing and blending technology to determine the application method and conditions.
3. BT-303 can be harmoniously combined with various admixtures, such as early strength agents, air entrainment agents, and retarders. Pre-usage testing is imperative. Avoid mixing BT-303 with naphthalene series water reducers.
4. For concrete formulations incorporating active admixtures like fly ash and slag, calculate the water-reducing agent dosage based on the total cementing material weight.
Package Options: Available in 220 kg drums, 23.5 tons per Flexitank, or 1100 kg IBC containers. Custom packaging is available upon request.
Storage: Ensure BT-303 Superplasticizer Liquid is kept in a well-ventilated, dry warehouse at temperatures ranging between 2-35 degrees Celsius. The packaging must remain intact and unsealed to guarantee a shelf life of one year. It is crucial to protect the product from direct sunlight and freezing conditions.
BT-303 is a revolutionary, independently developed slump-preserving polycarboxylic acid water reducer. It remarkably curtails the slump loss of concrete. Ideal for high water-reducing applications, it is versatile in use for pumping concrete, super-fluid self-compacting concrete, high-strength and high-performance concrete, and commercial concrete projects.
In the alkaline environment of concrete, this product's molecular structure facilitates a slow release of reactive groups with dispersive properties. This leads to continued dispersion of the cement, effectively inhibiting slump loss and maintaining concrete consistency.
