Introducing the BT-302 Superplasticizer Liquid: A state-of-the-art formulation designed for premium slump retention applications. Developed from TPEG through advanced free radical polymerization, this innovative product integrates a revolutionary slow-release group. When mixed into concrete's alkaline milieu, BT-302 gradually disperses a function group, expertly maintaining cement dispersion and dramatically curbing slump loss. While its water reduction rate is modest, BT-302's prowess in slump protection is unparalleled, making it a trusted companion for water-reducing liquors like JS-101B and JS-101A. Ideal for high-strength concrete, BT-302 excels across a spectrum of engineering feats: from pumping concrete, super-flow self-compacting mixes, to high-performance structures. It serves as a cornerstone in elite projects such as high-speed railways, expressways, hydropower stations, and extraordinary civil engineering undertakings.
2. Relish in superior slump retention, preserving concrete's consistency for an astounding 2-hour duration without degradation.
3. While its low water reduction necessitates synergy with water-reduction agents, the results are overwhelmingly positive and visible.
4. Thanks to its minimal viscosity and thixotropy, BT-302 is tailor-made for concrete with reduced water-cement ratios, ensuring flawless application.

2. BT-302 is critically acclaimed for its applications in high-speed railways, nuclear power plants, water conservancy initiatives, subways, large-scale bridges, expressways, and maritime structures, marking its essential role in national large-scale and flagship projects.
3. Tailored for both industrial and civil construction ventures, as well as commercial concrete batching facilities. Its adaptability and versatility are virtually limitless.
1. BT-302 presents as a colorless or faint yellow liquid. Typically employed at 0-20% with a water-reducing agent. Combine it with other minor materials to craft an efficient water-reducing agent, with usual dosages ranging from 1% to 3% of total cementing material weight.
2. Prior to using BT-302 or when changing cement and gravel types or batches, conduct thorough adaptability testing. Use results to devise the optimal water-reducing agent proportion.
3. While BT-302 can stand alone, it's often recommended to blend with water-reducing and set-retarding liquors to minimize slump loss. Pair with functional aids to create admixtures enhancing retarder, early strength, antifreeze, or pumping properties. Thorough testing and compounding should guide application methods.
4. BT-302 collaborates seamlessly with admixtures like early strength agents, air-entraining agents, and retarders. Test compatibility prior to use. Do not mix with naphthalene-based water reducers.
5. Cement and mix ratios should be defined through testing. During application, mix the calibrated water into the concrete mixer concurrently after conducting rigorous mixing tests to assure quality.
6. For active admixtures like fly ash and slag, determine the water-reducing agent amount as a percentage of the total cementing material weight.
