Introducing BT-302, a pioneering superplasticizer liquid that elevates slump retention to new heights. Crafted through advanced free radical polymerization of TPEG, this revolutionary product integrates a novel sustained-release group. Within concrete's alkaline environment, BT-302 gradually unveils its dispersive prowess, maintaining cement's fluidity like never before. While it exhibits a lower water reduction rate, its unparalleled slump protection is simply unmatched. BT-302 shines brightest when paired with water-reducing agents like JS-101B and JS-101A, especially in high-strength concrete where superior slump retention is crucial. Its versatility is evident in various engineering masterpieces, from fluid self-compacting concrete to high-performance mixtures for high-speed railways, expressways, hydro-power stations, and monumental infrastructure projects.
2. Revel in extraordinary slump performance, as BT-302 ensures concrete retains its consistency for an outstanding 2 hours without any loss.
3. Though a lower water reduction rate suggests pairing with water-reduction mother liquors, the resulting performance is exceptional.
4. Its low viscosity and thixotropy make BT-302 an ideal choice for concrete with reduced water-cement ratios, enhancing workability and cohesiveness.

2. Its broad applicability extends to high-speed railways, nuclear power plants, and water conservancy projects. BT-302 is indispensable in subways, large bridges, expressways, harbors, and wharves, becoming a vital component of national large-scale and critical undertakings.
3. Perfectly suited for diverse industrial and civil construction ventures as well as commercial concrete mixing stations, BT-302's versatility is boundless.
1. Presented as a colorless or light yellow liquid, BT-302 is optimally used at 0-20% concentration when combined with a water-reducing mother liquor. Mix with other components to create a potent water-reducing agent, usually making up 1% to 3% of the entire cementing material weight.
2. Prior to deployment, always conduct adaptability tests on BT-302 with your specific cement and gravel to establish the most effective water-reducing agent ratio based on test results.
3. While BT-302 can be utilized independently, it is often recommended to synergize with water-reducing and set-retarding agents to minimize slump loss. Combine with functional aids for enhanced admixtures featuring retarder, early strength, antifreeze, or pumping attributes. Let testing and compounding expertise guide application methods.
4. BT-302 blends seamlessly with other admixtures like early strength agents, air-entraining agents, and retarders. Ensure compatibility through preliminary testing while avoiding combinations with naphthalene series water reducers.
5. Cement and concrete mix ratios should be determined through comprehensive testing. Integrate the mixed and measured water into the concrete mixer simultaneously, following mixing tests to ensure optimum concrete quality.
6. For active admixtures like fly ash and slag, calculate the water-reducing agent proportion based on the full weight of cementing materials, ensuring precision and consistency.
