Product Description

BT-303 Polycarboxylate Superplasticizer
50% (High slump retaining type)
Product Introduction
The BT-303 represents the pinnacle of advanced chemical engineering, a slow-releasing and slump-protecting marvel meticulously crafted using TPEG through free radical polymerization. It incorporates a groundbreaking sustained-release group into its synthesis. In the alkaline environment of concrete, this innovative slow-releasing group within its molecular structure gradually unleashes a dispersive function, thereby extending the dispersal process of cement. This process is key in mitigating concrete slump loss. It is an impressive engineering feat. It boasts a low water reduction rate, but its exceptional performance in maintaining slump is unparalleled. This superplasticizer is predominantly utilized in high-strength concrete where slump protection is paramount. Its versatility extends to various applications, including pumping concrete, super-flow self-compacting, and high-strength high-performance concrete. It has been integral to construction endeavors like high-speed railways, expressways, hydro-power projects, and other monumental engineering feats.


Product Features
1. Exhibits extraordinary slump retention, allowing concrete to maintain slump for 2 hours without degradation.

2. Owing to its low water reduction rate, it is typically paired with water-reduction-type mother liquors for optimal results.

3. Its low viscosity and thixotropy make it perfectly suited for concrete with a low water-cement ratio.

4. The release rate is more gradual compared to BT-302, typically occurring after an hour, subject to certain variations based on concrete material characteristics.

How to Use

1. This product is a colorless to light yellow liquid. Standard dosage involves mixing 0-30% of this mother liquor with water-reducing mother liquor, alongside other minor components, to formulate a complete water-reducing agent. The typical usage of this agent is about 1% to 3% of the total cementing material weight.
2. Prior to utilizing this product, or when switching the type and batch of cement and gravel, adaptation tests must be conducted to ensure compatibility. Test results should inform the proportion for the water-reducing agent.
3. While generally not used alone, this product can be combined with water-reducing and set-retarding mother liquors to reduce concrete slump loss. It can also be compounded with other agents for additional functions like retarder, early strength, antifreeze, or pumping capabilities. Application methods and conditions should be determined through testing and formulation technology.
4. This product is compatible with other admixtures, such as early strength agents, air entrainment agents, and retarders, provided appropriate testing is conducted before use. However, it should not be mixed with naphthalene series water reducers.
5. To achieve unparalleled concrete quality, ensure the concrete cement and mix ratio are determined through pre-testing. During application, blend the mixed and measured water by adding it to the concrete mixer simultaneously. Conduct a thorough mixing test beforehand to guarantee the superior quality and performance of your concrete.
6. In scenarios where active admixtures like fly ash and slag are constituents of the concrete mix, it is imperative to account for the water-reducing agent as part of the total cementitious material. This meticulous calculation ensures optimal performance and longevity of the concrete.
