Introducing the groundbreaking BT-303, a new era of slump-preserving polycarboxylic acid water reducers, expertly crafted by Shandong Gaoqiang New Material Technology Co., Ltd. Designed to dramatically curb concrete slump loss, BT-303 is the ultimate solution for high water-reducing needs. Its versatility makes it indispensable for an array of concrete applications including pumping, super-fluid self-compacting, high-strength, high-performance, and commercial concrete, promising exceptional results across the board.
This innovative product's molecular structure is ingeniously designed with active groups like ester and amide groups. This composition results in a polycarboxylic acid superplasticizer that boasts remarkable slump retention. In the alkaline environment of concrete, the ester groups undergo gradual hydrolysis, transforming into carboxylic acid groups. These are absorbed onto the cement particle surfaces, providing an outstanding slow-release mechanism for slump protection, ensuring the integrity and workability of your concrete.
Within concrete's alkaline conditions, the reactive groups within BT-303's molecular structure are released slowly, providing a continuous dispersing effect. This contributes significantly to maintaining cement dispersion, effectively minimizing slump loss and enhancing concrete performance for longer durations.
(1) Remarkable slump retention capability, maintaining over 80% of initial slump even after an hour, efficiently tackling the challenge of rapid slump loss. This feature ensures that fresh concrete retains its excellent workability, setting the stage for optimal hardening and lasting durability.
(2) Superior performance post-application. Fresh concrete benefits from excellent workability and hardens into a durable, resilient structure.
(3) Exceptional compatibility with various cement types including Portland, ordinary Portland, slag silicate, fly ash, pozzolan cement, and numerous admixtures, making it a versatile choice for diverse construction needs.
(4) Eco-friendly and sustainable, BT-303 is produced with no release of waste products, aligning with green environmental standards and ensuring sustainability throughout its manufacturing process.

(1) Ideal for crafting a variety of concrete types - from early-strength to retarded, precast to cast-in-place, and including large flow, self-compacting, mass, high-performance, and fair-faced concretes. Perfectly suited for all types of industrial and civil buildings, particularly for low-grade commercial concrete.
(2) BT-303 finds its place in critical national projects like high-speed railways, nuclear power, water conservancy and hydropower initiatives, subways, large bridges, expressways, as well as harbor and wharf constructions.
(3) Adaptable to an array of industrial, civil construction, and commercial concrete mixing plants, ensuring widespread usage across various sectors.
1. Recommended dosage ranges from 0.6% to 1.2% based on total cementitious materials. The optimal amount should be experimentally determined in accordance with specific engineering materials and conditions. It is perfect for use alone or combined with high water-reducing agents.
2. While primarily used alone, BT-303 can be combined with water-reducing and set retarding mother liquors to tackle slump loss. Additionally, it can be mixed with functional aids to enhance functionalities like retardation, early strength, antifreeze, and pumping. Application methods should be defined through testing and compounding technology.
3. Compatibility with other admixtures, such as early strength agents, air entrainment agents, and retarders, is possible but requires preliminary testing. It should not be mixed with naphthalene-based reducers to avoid adverse effects.
4. In mixes including active admixtures like fly ash and slag, the water-reducing agent must be calculated based on the total amount of cementitious materials to maintain desired performance.
Packaging options are flexible: 220kgs per drum, 23.5 tons per Flexitank, or 1100kg per IBC, with customization available upon request to meet your specific needs.
Storage: To ensure optimal longevity, store this product in a well-ventilated, dry warehouse at temperatures ranging from 2-35 degrees Celsius. Keep the packaging intact and unsealed to preserve its quality, with a shelf life extending up to one year. Essential precautions include protection from direct sunlight and freezing conditions, ensuring product integrity over time.
The BT-303 represents a cutting-edge advancement in slump-preserving polycarboxylic acid water reducers, uniquely developed by our company. This powerful solution effectively curbs concrete slump loss, making it ideal for high water-reducing applications. It finds extensive application in pumping concrete, super-fluid self-compacting, high-strength, and high-performance concrete, as well as commercial concrete projects.
Within the concrete's alkaline environment, the reactive groups in this product's molecular structure gradually discharge dispersive groups. This ongoing dispersal of cement effectively curbs concrete slump loss, ensuring prolonged workability and quality.
(1) Significant slump retention value, maintaining over 80% of fresh concrete slump after one hour, effectively addressing rapid slump loss. The product's prowess lies in its ability to sustain more than 80% of concrete's initial slump after an hour, expertly tackling the issue of quick slump loss.
(2) Exceptional concrete performance post-application. Fresh concrete boasts superior workability alongside excellent hardening and durability characteristics.
(3) Diverse adaptability. Demonstrates broad compatibility with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and various admixtures.
(4) Eco-friendly and sustainable, producing no waste byproducts during its production process.
