BT-302 Polycarboxylate Superplasticizer
High Slump Retention Solid 50%
Product Introduction
BT-302 introduces a revolutionary fast-release formula that is engineered to elevate concrete performance. It excels in maintaining slump, acting as a mother liquor derived from TPEG via advanced free radical polymerization, and integrates a cutting-edge sustained-release group into its synthesis. In the alkaline environment of concrete, this product's innovative slow-release mechanism gradually disperses the group with dispersive capabilities, effectively maintaining cement dispersion. This process prolongs the slump life of concrete,ensuring optimal performance even with its moderate water reduction rate. Remarkably, it delivers outstanding slump protection,making it indispensable for critical applications.Typically paired with water-reducing agents, BT-302 is engineered for high-strength concrete demanding enhanced slump retention, and is extensively utilized in pumping concrete, super-flow self-compacting, and high-strength concrete solutions. Ideal for commercial concrete in high-speed railways, expressways, hydroelectric projects, and other expansive engineering endeavors.
Main Features
* The slow-release mother liquor is designed for a rapid onset, outperforming traditional PCE mother liquors.
Typically initiates release after 30 minutes, with variations based on material composition.
* Boasts exceptional slump retention, preserving concrete slump for up to 2 hours without degradation.
* Its low water reduction rate necessitates combination with water-reducing agents for optimal results.
* With its low viscosity and thixotropic properties, it is ideally suited for concrete mixes with low water-cement ratios.

Applications
1. Perfectly suited for early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concretes. Ideal for premix cast-in-place concrete in industrial and civil constructions, especially for lower-grade commercial concretes.
2. Extensively applicable to high-speed railways, nuclear power, water conservancy, hydroelectric projects, subways, large bridges, expressways, harbors, wharves, and other significant national projects.
3. Adaptable for various industrial, civil construction sites, and commercial concrete mixing stations.
How to Use
1. This product is available as a colorless or light yellow liquid. Dosage: Typically,utilize 0-30% of this mother liquor with water-reducing agents, combining with other minor ingredients to formulate a water-reducing agent. The typical dosage is 1% - 3% of the total weight of cementitious materials.
2.Conduct adaptability tests with cement and gravel before using or changing types and batches of these materials. Adjust the water-reducing agent proportion based on test results.
3.While it can be used alone, it is not typically recommended to do so without combination with other agents for best results. The Efficient Slump Retention Polycarboxylate Superplasticizer Liquid is expertly crafted to be combined with a water-reducing mother liquor, seamlessly integrating into your concrete solutions. This product serves as a set retarding marvel, enhancing the longevity and robustness of your concrete projects. When paired with a set retarding mother liquor, this superplasticizer significantly minimizes concrete slump loss, ensuring remarkable consistency. Further elevate your concrete's performance by integrating this liquid with functional aids, enhancing versatility and application. By compounding with functional aids, you can achieve admixtures that boast remarkable properties such as retarder, early strength, antifreeze, and pumping functionalities.This ensures your concrete mixtures are cutting-edge and fit for purpose. To unlock the full potential of this product, application methods and conditions should be meticulously determined through rigorous testing and advanced compounding technology.This will ensure optimal performance in your specific use case.
4.This versatile product is designed to harmonize with other admixtures, such as early strength agents, air entrainment agents, and retarders, offering comprehensive solutions for concrete enhancement. It is essential to conduct tests prior to use and avoid mixing with naphthalene series water reducers.
5.When devising your concrete mix, it is critical to perform testing to determine the precise cement and mix ratios. During application, ensure that the mixed and measured water is added simultaneously to the concrete mixer. Pre-use mixing tests are crucial to guarantee the superior quality of the final concrete product.e.
6.In scenarios where active admixtures like fly ash and slag are included in the concrete ratio, it is vital to calculate the water-reducing agent based on the total amount of cementing materials for optimal results.
