BT-303 is a pioneering, next-generation slump-preserving polycarboxylic acid water reducer, crafted meticulously by Shandong Gaoqiang New Material Technology Co., Ltd. This product stands out by substantially curbing the slump loss in concrete, making it an excellent choice for high water-reducing applications. Ideal for pumping concrete, super-fluid self-compacting projects, high-strength and high-performance concrete, as well as commercial concrete, BT-303 redefines versatility and efficiency.
The ingenious molecular design of BT-303 incorporates active groups like ester and amide groups, ensuring superior slump retention. In the concrete's alkaline environment, these ester groups gradually hydrolyze into carboxylic acid groups, which adsorb onto the cement particles' surface, providing an outstanding slow-release slump protection effect.
In concrete's alkaline milieu, the reactive groups within BT-303's molecular framework release dispersing agents gradually, continuously dispersing the cement. This innovative action effectively curtails concrete slump loss, ensuring stability and performance.
(1) Exceptional slump retention, maintaining over 80% of fresh concrete's original slump after one hour. This feature adeptly addresses the challenge of rapid slump loss. The innovative formulation ensures that concrete retains a high degree of workability and durability after one hour, offering a robust solution against rapid slump loss.
(2) Post-application excellence. BT-303 enhances fresh concrete's workability while significantly improving its hardening and long-term durability.
(3) Extensive versatility, showcasing wide compatibility with a range of cements including Portland, ordinary Portland, slag silicate, fly ash, pozzolan, and various admixtures.
(4) Environmentally conscious, the manufacturing process of BT-303 aligns with green principles, producing no three waste products.

(1) Perfect for crafting early-strength, retarded, precast, cast-in-place, large flow, and self-compacting concrete, as well as mass, high-performance, and fair-faced concrete. Especially beneficial for low-grade commercial concrete in both industrial and civil building projects.
(2) Broadly applicable in national and significant projects, including high-speed railways, nuclear power, water conservancy and hydropower projects, subways, large bridges, expressways, harbors, and wharfs.
(3) Suitable for various industrial and civil construction applications, and essential in commercial concrete mixing plants.
1. The recommended dosage varies between 0.6%~1.2% based on the total cementitious material volume, with optimal amounts determined through experimental trials. BT-303 can be used in conjunction with other high water-reducing agents or independently, dependent on project specifics.
2. While typically not used alone, BT-303 can be combined with water-reducing and set retarding mother liquors to mitigate slump loss, or with functional additives to craft admixtures with retarding, early strength, antifreeze, and pumping benefits. Application is refined through testing and compounding technology.
3. BT-303 is compatible with other admixtures such as early strength agents and air-entraining agents. Pre-use testing is advised, and it should not be mixed with naphthalene series water reducers.
4. When integrating active admixtures like fly ash or slag, calculate the water-reducing agent based on the total cementitious material volume.
Package: Available in 220kg drums, 23.5 tons per Flexitank, or 1100kg IBC, with custom packaging options upon request for tailored logistical solutions.
Storage: Ensure the BT-303 Superplasticizer Liquid is kept in a ventilated, dry warehouse at temperatures ranging between 2-35 degrees. Maintain the packaging intact and unopened to preserve its quality, offering a robust shelf life of one year. Avoid direct sunlight and freezing conditions to ensure optimal performance.
The BT-303 Superplasticizer Liquid is an innovative, new-generation, slump-preserving polycarboxylic acid water reducer. Developed by our company, it effectively reduces slump loss in concrete, making it ideal for high water-reducing applications. Its versatility spans across pumping concrete, super-fluid self-compacting, high-strength, and high-performance as well as commercial concrete.
In alkaline conditions, the reactive groups within the product's molecular structure gradually release dispersing agents, effectively continuing to disperse cement particles and preventing slump loss.
(1) Large slump retention value, maintaining over 80% of initial slump after 1 hour. This efficiently addresses rapid concrete slump loss. of the initial slump of fresh concrete after 1 hour, tackling the issue of rapid slump loss effectively.
(2) Outstanding performance post-application. Fresh concrete exhibits excellent workability, hardening, and durability.
(3) Versatile adaptability. Compatible with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and a variety of admixtures.
(4) Eco-friendly production with no waste products, supporting sustainable practices.

(1) Optimally designed for the creation of early-strength, retarded, precast, cast-in-place, large flow, self-compacting, mass, high-performance, and fair-faced concrete. Perfectly suited for industrial and civil structures, including ready-mixed and cast-in-situ varieties, especially low-grade commercial concrete projects.
(2) With versatility at its core, this product is ideal for prestigious national and key infrastructure projects: spanning high-speed railways, nuclear power installations, water conservancy, hydropower projects, metropolitan subways, expansive bridges, expressways, and bustling harbors and wharfs.
(3) Tailored for diverse industrial, civil construction, and commercial concrete mixing facilities, ensuring superior performance across applications.
1. Recommended dosage ranges from 0.6% to 1.2%, calculated relative to the total cementitious materials. The optimal dosage is best determined via experimentation tailored to specific engineering materials and attributes. Compatible for solo use or in synergy with high water-reducing polycarboxylic acid agents.
2. This product shines in single or combined applications. Use it with water-reducing or set-retarding master agents to curb concrete slump loss, or blend with functional aids to craft admixtures with enhanced properties like retardation, early strength, antifreeze, and pumping capabilities.
