BT-303 Polycarboxylate Superplasticizer
50% (High slump retaining type)
Product Introduction
Introducing BT-303, the advanced evolution of polycarboxylate superplasticizers crafted meticulously from TPEG through free radical polymerization. This state-of-the-art solution integrates an innovative sustained-release mechanism. In the alkaline environment of concrete, BT-303 methodically releases molecular groups designed for dispersion, continually working to disperse cement particles and inhibit premature slump loss. It stands as a beacon of innovation, offering unrivaled performance in maintaining concrete slump. It boasts a modest water reduction rate, yet delivers exceptional slump protection capabilities. Primarily tailored for high-strength concrete demanding superior slump retention, BT-303 is extensively utilized in diverse applications such as pumping concrete, super-flow self-compacting, and high-strength high-performance concrete. Its versatility makes it ideal for commercial concrete needed in high-profile projects like high-speed railways, expressways, hydropower initiatives, and other significant engineering marvels.
Product Features
1. Possesses exceptional slump retention, ensuring concrete remains slump-free for up to 2 hours.
2. The low water reduction feature suggests it is best used in conjunction with a water-reducing mother liquor for optimal results.
3. Exhibiting low viscosity and thixotropy, it is ideally suited for concrete with a low water-cement ratio.
4. Offers a release profile slower than BT-302, typically activating after 1 hour, though this may vary based on concrete materials. Certain fluctuations).

Application
1. Perfect for early-strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concretes. It's especially useful for lower-grade commercial concrete in industrial and civil building projects.
2. An excellent choice for large-scale national projects including high-speed railways, nuclear power plants, water conservancy, subways, expansive bridges, expressways, harbors, and wharves.
3. Ideal for various industrial and civil construction and commercial concrete mixing stations.
How to Use
1. BT-303 appears as a colorless or light yellow liquid. Typical dosage: Mix 0-30% of this mother liquor with water-reducing mother liquor and other additives to create a water-reducing admixture. Use 1% to 3% of the total cementing materials by weight.
2. Conduct compatibility tests with cement and gravel before use or when changing material batches to establish the appropriate water-reducing admixture ratio.
3. While BT-303 can be used alone, it is generally more effective when combined with water-reducing or set-retarding mother liquors. It can also be mixed with additives for retarding, early strength, antifreeze, or pumping purposes. Thorough testing and precise compounding techniques are recommended.
4. BT-303 can be mixed with various admixtures like early strength agents, air entrainment agents, or retarders. Testing is crucial before use, and it should not be combined with naphthalene series water reducers.
5. To achieve the finest results, it is essential that the concrete cement and mix ratios are meticulously determined through rigorous testing. During application, ensure that the mixed and measured water is introduced simultaneously with other materials into the concrete mixer. Prior to full-scale use, perform a comprehensive mixing test to guarantee unparalleled quality and consistency of the concrete.
6. In scenarios where active admixtures such as fly ash and slag are incorporated into the concrete mix, it is crucial to recalibrate the water-reducing agent's quantity to align with the total amount of cementing materials. This ensures optimal performance and durability of the concrete.
