Introducing the BT-303, a groundbreaking slump-preserving polycarboxylic acid water reducer, meticulously crafted by Shandong Gaoqiang New Material Technology Co., Ltd. This superior formulation dramatically curtails concrete slump loss, making it the ideal choice for high water-reducing applications. Versatile and robust, it is perfectly suited for a wide array of concrete types including pumping concrete, super-fluid self-compacting concrete, high-strength and high-performance concrete, as well as commercial concrete.
This innovative product boasts a molecular structure enriched with active groups such as ester and amide, creating a polycarboxylic acid superplasticizer with exceptional slump retention capabilities. When exposed to the alkaline conditions within concrete, these ester groups gradually hydrolyze into carboxylic acid groups, adhering to the cement particles and delivering a remarkable slow-release slump protection effect.
In the alkaline environment of concrete, the reactive groups in the product's molecular structure methodically release dispersing agents, facilitating continuous cement dispersion. This action effectively diminishes the risk of slump loss in concrete.
(1) The product ensures a significant slump retention value, allowing the slump to maintain over 80% of its original state even after 1 hour. This feature adeptly addresses the challenge of swift concrete slump loss. of the slump of the fresh concrete after 1 hour, which can effectively solve the problem of rapid concrete slump loss.
(2) Post-application, the concrete exhibits outstanding qualities. The fresh mix offers excellent workability, while the hardened concrete demonstrates superior durability and endurance.
(3) Remarkable adaptability marks this product, as it seamlessly integrates with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and a range of admixtures.
(4) Emphasizing sustainability, this solution is green and environmentally friendly, with no three waste products generated during its production process.

(1) Perfect for crafting early-strength, retarded, precast, cast-in-place, large flow, self-compacting, mass, high-performance, and fair-faced concrete. It is also ideal for industrial and civil buildings, particularly low-grade commercial concrete, and in medium ready-mixed and cast-in-situ forms.
(2) Its application extends to a multitude of national and pivotal projects, including high-speed railways, nuclear power plants, water conservancy and hydropower developments, subways, expansive bridges, expressways, harbors, and wharfs.
(3) Suitable for diverse industrial and civil construction projects, as well as commercial concrete mixing facilities.
1. The typical dosage ranges from 0.6% to 1.2% (calculated based on the total cementitious material volume). Optimal dosage should be ascertained through experimental trials tailored to specific engineering materials and conditions. It can be used in combination with high water reducing polycarboxylic acid agents or independently.
2. This product is highly versatile and can be used solo (though not typically recommended) or blended with water-reducing and set retarding mother liquors to mitigate concrete slump loss. Alternatively, it can be compounded with functional aids to produce admixtures with additional functionalities such as retardation, early strength, antifreeze, or pumping. Usage methods and conditions should be verified through testing and compounding technology.
3. It is compatible with other admixtures like early strength agents, air entrainment agents, and retarders, but must be tested prior to use. Avoid combining with naphthalene series water reducers.
4. When using active admixtures such as fly ash and slag in concrete formulations, the water-reducing agent dosage should be calculated as part of the total cementitious material volume.
Package: Available in 220kgs drums, 23.5 tons per Flexitank, 1100kg IBC, or customized packaging options upon request.
Storage: Keep stored in a well-ventilated and dry warehouse, maintaining temperatures between 2-35 degrees Celsius. Ensure packaging remains intact and unopened for a shelf life of one year. Protect the product diligently from direct sunlight and freezing conditions.
BT-303 represents a cutting-edge slump-preserving polycarboxylic acid water reducer, developed independently by our company. It efficiently curtails slump loss in concrete, making it ideal for high water-reducing applications. Its versatility allows for extensive use in pumping concrete, super-fluid self-compacting, high-strength, high-performance, and commercial concrete applications.
In the alkaline milieu of concrete, the reactive groups within the product's molecular structure progressively unleash dispersing agents, facilitating an ongoing dispersion of cement. This mechanism effectively mitigates concrete's slump loss.
(1) High Slump Retention: Achieving more than 80% of the initial slump after one hour, it effectively counters rapid slump loss in concrete. The performance of fresh concrete remains exceptional, maintaining good workability and exhibiting excellent hardening and durability.
(2) Outstanding Performance: Post-application, concrete demonstrates superior workability and enduring strength.
(3) Broad Compatibility: Exceptionally compatible with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and various admixtures.
(4) Eco-friendly: Environmentally conscious with no production of hazardous waste.
