BT-303, a cutting-edge advancement in polycarboxylic acid water reducers, has been meticulously developed by Shandong Gaoqiang New Material Technology Co., Ltd. This innovative product is engineered to significantly curb slump loss in concrete, ensuring superior water-reducing capabilities. Ideal for applications involving pumping concrete, super-fluid self-compacting concrete, high-strength, high-performance, and commercial concrete, BT-303 stands as a versatile, high-performance solution tailored for modern construction needs.
This revolutionary product is crafted with a unique molecular structure, incorporating active groups such as ester and amide groups. This structure enhances its effectiveness as a polycarboxylic acid superplasticizer, providing remarkable slump retention properties. In the naturally alkaline environment of concrete, ester groups undergo gradual hydrolysis into carboxylic acid groups, which then adsorb onto cement particles, delivering a sustained slow-release protective effect against slump loss.
Within the alkaline milieu of concrete, this product's reactive molecular groups gradually unleash dispersing properties, continuously facilitating cement dispersion. This ensures a prolonged slump retention effect, effectively impeding any potential slump loss in concrete, thus maintaining its optimal workability over time.
(1) Remarkable slump retention capability ensures that the slump remains above 80% of the original fresh concrete slump after one hour. This effectively addresses and resolves the challenge of rapid slump loss in concrete.
(2) Exceptional post-application performance guarantees that fresh concrete exhibits superior workability, alongside outstanding hardening and long-term durability.
(3) Extensive adaptability to a wide range of materials, including Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and various admixtures.
(4) Eco-friendly and sustainable production process with zero waste generation, aligning with green environmental standards.

(1) Perfectly suited for crafting early-strength concrete, retarded concrete, precast concrete, cast-in-place concrete, large flow concrete, self-compacting concrete, and more. It's versatile across diverse industrial and civil buildings, particularly advantageous for low-grade commercial concrete.
(2) Ideal for deployment in prestigious national and key infrastructure projects, including high-speed railways, nuclear power plants, water conservancy projects, subways, large bridges, expressways, harbors, and wharfs.
(3) Widely applicable for various industrial and civil construction endeavors and commercial concrete mixing facilities.
1. Recommended dosage ranges from 0.6% to 1.2% of the total cementitious materials. Optimal dosage should be experimentally determined based on specific engineering materials and characteristics. Suitable for use alone or in combination with high water-reducing polycarboxylic acid agents.
2. The product can also be used in combination with water-reducing mother liquor and set retarding mother liquor to mitigate slump loss in concrete. Alternatively, it can be compounded with functional aids to create admixtures with retarding, early strength, antifreeze, or pumping functionalities. Application methods should be determined via testing and compounding technology.
3. Compatible with other admixtures like early strength agents, air entrainment agents, retarders, etc. Testing prior to use is advised. Avoid mixing with naphthalene series water reducers.
4. When using active admixtures like fly ash and slag, calculate the water-reducing agent dosage based on the total cementitious material content.
Packaging options include 220kg drums, 23.5 tons in Flexitank, or 1100kg IBCs, with custom requests accommodated to suit specific needs.
