Introducing the cutting-edge BT-303, an advanced slump-preserving polycarboxylic acid water reducer, meticulously developed by Shandong Gaoqiang New Material Technology Co., Ltd. This innovative product is engineered to significantly mitigate slump loss in concrete, making it an indispensable ally for high water-reducing polycarboxylic acid reductions. With its versatile application potential, BT-303 is ideal for pumping concrete, super-fluid self-compacting mixtures, as well as high-strength, high-performance, and commercial concrete formulations.
At the heart of this product's powerful capabilities lies its sophisticated molecular structure, which incorporates active ester and amide groups to craft a polycarboxylic acid superplasticizer with outstanding slump retention properties. In the alkaline environment of concrete, these ester groups gradually transform into carboxylic acid groups, adhering to cement particles to deliver a remarkable slow-release slump protection effect.
In the alkaline milieu of concrete, the reactive groups within this product's molecular architecture release dispersing groups at a measured pace, perpetually dispersing cement particles and effectively curtailing concrete slump loss.
(1) Exceptional Slump Retention: This product boasts an impressive retention rate, maintaining over 80% of the initial slump of fresh concrete after one hour, effectively addressing rapid slump loss challenges. This ensures a robust solution to the common issue of swift slump reduction, maintaining optimal workability in concrete applications.
(2) Superior Concrete Performance: Post-application, concrete exhibits excellent workability, along with outstanding hardening and long-term durability.
(3) Versatile Adaptability: This product showcases broad adaptability across various cement types including Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and a wide array of admixtures.
(4) Environmentally Conscious: With a commitment to sustainability, this product is produced with no generation of three waste products, aligning with green, eco-friendly practices.

(1) Versatile Applications: BT-303 is suitable for crafting a range of concrete types including early-strength, retarded, precast, cast-in-place, large flow, self-compacting, mass, high-performance, and fair-faced concretes. It is particularly beneficial for various industrial and civil construction projects, especially low-grade commercial concrete.
(2) Comprehensive Utilization: Ideal for major national and key infrastructure projects, including high-speed railways, nuclear power facilities, water conservancy and hydropower projects, subways, grand bridges, expressways, harbors, and wharfs.
(3) Widely Suitable: Perfectly suited for diverse industrial, civil construction, and commercial concrete mixing facilities, ensuring optimal performance across applications.
1. Recommended Usage: Typically, the dosage ranges from 0.6% to 1.2% (calculated on the total cementitious materials). Optimize the dosage through experimental analysis based on engineering materials and characteristics. It works well both as a standalone product or in combination with high water-reducing polycarboxylic acid agents.
2. Flexible Application: While primarily used in combination, this product can function alone or be paired with water-reducing or set-retarding mother liquors to curb concrete slump loss. It can also be formulated with functional aids for retarder, early-strength, antifreeze, and pumping functions, with methods determined by testing and compounding technology.
3. Compatibility: BT-303 harmonizes well with other admixtures such as early strength agents, air entrainment agents, and retarders. Conduct tests prior to use, and avoid combining with naphthalene series water reducers.
4. Special Considerations: In concrete formulations containing active admixtures like fly ash and slag, calculate the water-reducing agent based on the total cementitious material weight.
Packaging Options: Available in 220kg drums, 23.5-ton Flexitanks, and 1100kg IBC containers. Custom packaging requests are also accommodated to suit diverse logistical needs.
Storage: Securely store in a well-ventilated, dry warehouse, maintaining a temperature range of 2-35 degrees Celsius. Ensure packaging is intact and unopened to enjoy a shelf life of up to one year. Keep away from direct sunlight and freezing conditions to preserve product quality.
BT-303 represents a new generation of slump-preserving polycarboxylic acid water reducers, developed independently by our company. This innovative product significantly curtails concrete slump loss, making it ideal for high water-reduction applications. It finds extensive use in pumping concrete, super-fluid self-compacting concrete, high-strength and high-performance concrete, as well as commercial concrete solutions.
In the alkaline milieu of concrete, active molecular groups in this product release dispersing agents slowly over time, facilitating the continued dispersion of cement particles and significantly mitigating concrete slump loss.
(1) Exceptional slump retention: Maintains over 80% of fresh concrete slump after 1 hour, effectively addressing rapid slump loss challenges. This ensures smoother concrete operations and superior end results.
(2) Outstanding post-application performance: Fresh concrete exhibits superb workability, coupled with excellent hardening and long-lasting durability.
(3) Versatile adaptability: Compatible with a wide array of cements, including Portland, ordinary Portland, slag silicate, fly ash, pozzolan cements, and various admixtures.
(4) Environmentally conscious: Production process yields no hazardous waste, emphasizing our commitment to sustainability.

1. The typical dosage ranges from 0.6% to 1.2% based on the total cementitious materials. Discovering the optimal dosage necessitates thorough experimentation with engineering materials and characteristics. This product harmonizes perfectly with high water-reducing polycarboxylic acid agents, or can be used independently, to achieve superior results.
2. While this product can be used solo, optimal results are often achieved through combination. Blend with water-reducing and set-retarding mother liquors to minimize concrete slump loss. Alternatively, integrate with functional aids to craft admixtures featuring retarder, early strength, antifreeze, and pumping benefits. The specific application method and conditions should be refined through rigorous testing and compounding techniques.
