Presenting the BT-302 Slump Retention Superplasticizer, a revolutionary innovation poised to redefine concrete performance. This state-of-the-art mother liquor is meticulously crafted from TPEG through advanced free radical polymerization. At its core lies a newly integrated, sustained-release group, engineered to release gradually within the alkaline milieu of concrete. This gradual release of dispersive function groups ensures optimal cement dispersion, dramatically reducing slump loss. While its water reduction rate may be modest, BT-302 excels in slump protection, making it a premier choice for high-strength concrete applications. It's particularly indispensable when paired with water-reducing mother liquors like JS-101B and JS-101A. BT-302 stands out in numerous engineering feats, from pumping concrete and super-flow self-compacting concrete to high-strength, high-performance concrete and commercial concrete used in the nation's most ambitious infrastructure projects such as high-speed railways, expressways, and hydro-power stations.
2. Benefit from unparalleled slump performance, allowing concrete to sustain its slump for an extraordinary 2 hours without experiencing any decrement.
3. Although its low water reduction rate suggests a combination with water-reduction-type mother liquors, the outcomes unmistakably justify the approach.
4. With its low viscosity and thixotropic properties, BT-302 is perfectly tailored for concrete requiring a low water-cement ratio.

2. BT-302 extensively serves high-speed railways, nuclear power plants, water conservancy projects, subways, large bridges, expressways, harbors, and wharves, making it indispensable for the nation's major large-scale and key infrastructure projects.
3. Perfect for a vast range of industrial, civil construction projects, and commercial concrete mixing stations, BT-302 demonstrates remarkable versatility without limits.
1. BT-302 is a light yellow or colorless liquid, generally utilized by incorporating 0-20% of mother liquor with a water-reducing mother liquor. Additionally, combine it with other minor materials to formulate a potent water-reducing agent. Generally, the water-reducing agent should represent 1% to 3% of the total cementing material's weight.
2. Before applying BT-302 or changing the type and batch of cement and gravel, it's crucial to perform adaptability testing with the specific cement and gravel. Tailor the water-reducing agent's optimal proportion based on the test results.
3. Although BT-302 can be used independently, it is often recommended to blend it with water-reducing and set-retarding mother liquors to mitigate concrete slump loss. Alternatively, combine it with functional aids to develop admixtures featuring retarder, early strength, antifreeze, or pumping capabilities. Application methods and conditions should be defined by comprehensive testing and compounding technology.
4. BT-302 integrates seamlessly with other admixtures like early strength agents, air-entraining agents, and retarders. Prior compatibility testing ensures harmonious integration. Avoid mixing with naphthalene series water reducers.
5. Define concrete cement and mix ratios through rigorous testing. During application, simultaneously introduce the integrated and measured water into the concrete mixer, ensuring a thorough mixing test to maintain concrete quality.
6. When using active admixtures like fly ash and slag, calculate the water-reducing agent as a percentage of the total cementing material weight.
