Product Description

Introducing BT-303 Polycarboxylate Superplasticizer
Boasting an impressive 50% (High slump retaining capability)
Product Introduction
BT-303 is an innovative marvel in the realm of superplasticizers, crafted as a new generation slow-releasing and slump-retaining master solution. Derived from TPEG through free radical polymerization, this product introduces a pioneering sustained-release group within its synthesis. In the alkaline environment of concrete, the slow-releasing feature in its molecular makeup gradually unleashes a dispersive-functioning group, persistently dispersing cement particles to effectively curb concrete slump loss. While it boasts a relatively low water reduction rate, it excels in providing exceptional slump protection performance. Primarily tailored for high-strength concrete, it meets the stringent demands for slump protection. Its versatility is evident as it finds extensive application in pumping concrete, super-flow self-compacting, as well as high-strength, high-performance concrete. It is an ideal choice for commercial concrete in monumental engineering feats such as high-speed railways, expressways, hydro-power projects, and more.


Product Features
1. Exhibits extraordinary slump performance, maintaining concrete slump for up to 2 hours without significant loss.

2. With a low water reduction rate, it is typically used in combination with water-reducing mother liquors for optimal effectiveness.

3. Its low viscosity and thixotropic nature make it perfect for concrete with a low water-cement ratio.

4. The release timing is more gradual compared to BT-302, generally activating after 1 hour (adjustments may vary based on concrete material characteristics). Certain fluctuations apply).

2. Widely applicable in high-speed railways, nuclear power plants, water conservancy, hydro-power projects, subways, large bridges, expressways, harbors, and wharves, making it indispensable for national large and key projects.

3. Perfect for all forms of industrial, civil construction, and commercial concrete mixing facilities.



Usage Instructions

1. Available as a colorless or light-yellow liquid. Typical dosage involves using 0-30% mother liquor alongside water-reducing agents and other minor materials to create a water-reducing agent. The standard usage is 1% to 3% of the total weight of cementing materials.
2. Before deploying this product or changing cement and gravel types/batches, it's imperative to conduct adaptability tests. Formulate the appropriate water reducer proportion based on these tests.
3. Although this product can be used singly, it is generally recommended to combine it with water-reducing and set-retarding mother liquors for optimal results, reducing concrete slump loss. It can also be compounded with functional aids to create admixtures offering retarder, early strength, antifreeze, and pumping functions. Testing and compounding technologies determine the appropriate method and conditions.
4. Compatible with various admixtures such as early strength agents, air entrainment agents, and retarders, thorough testing is advised prior to use. Note: Avoid mixing with naphthalene series water reducers.
5. To achieve optimal performance in your concrete mix, it's crucial that the cement and mix ratio be determined through comprehensive testing. When incorporating the Gaoqiang Polycarboxylate Superplasticizer, ensure that both the additive and the measured water are introduced simultaneously into the concrete mixer. Conducting a pre-use mixing test is essential to guarantee the impeccable quality and integrity of your concrete.
6. If your concrete composition includes active admixtures such as fly ash or slag, it is important to calculate the water-reducing agent as a proportion of the entire cementing material volume. This ensures that the Gaoqiang Polycarboxylate Superplasticizer delivers its maximum water-reducing efficiency and maintains the concrete's robust properties.
