Introducing BT-302, a revolutionary superplasticizer liquid crafted with precision using TPEG and free radical polymerization. This state-of-the-art mother liquor boasts a unique sustained-release group, specifically designed for the alkaline environment of concrete. The slow-releasing group in BT-302's molecular framework gradually unveils a dispersive function group, ensuring effective cement dispersion and significantly curbing concrete slump loss. Despite its low water reduction rate, BT-302's unrivaled slump protection is unparalleled. It's ideally paired with water-reducing mother liquors like JS-101B and JS-101A, making it indispensable for high-strength concrete applications needing supreme slump retention. Perfect for a realm of engineering feats including pumping concrete, super-flow self-compacting concrete, high-strength high-performance concrete, and commercial concrete for high-speed railways, expressways, hydro-power stations, and more grand engineering ventures.
2. Benefit from extraordinary slump retention, allowing concrete to maintain its slump for an astounding 2 hours with zero slump loss.
3. Though its water reduction rate is modest, requiring synergy with water-reduction-type mother liquors, the results are nothing short of phenomenal.
4. With its low viscosity and minimal thixotropy, BT-302 is exceptionally well-suited for concrete with a reduced water-cement ratio.

2. BT-302 is extensively employed in high-speed railways, nuclear power plants, water conservancy projects, subways, large bridges, expressways, harbors, and wharves, making it a key player in national large-scale and pivotal projects.
3. Perfectly suited for a myriad of industrial and civil construction endeavors and commercial concrete mixing stations. Its versatility knows no limits.
1. This product is a colorless or pale yellow liquid. Typically, use 0-20% mother liquor in tandem with a water-reducing mother liquor. Additionally, combine with other minor materials to formulate a water-reducing agent. The water-reducing agent dosage generally ranges from 1% to 3% of the total cementing material weight.
2. Prior to BT-302 application or changes in cement and gravel type or batch, it is crucial to conduct adaptability testing. Based on test results, establish an optimal proportion for the water-reducing agent.
3. Although BT-302 can be used alone, it is often not recommended. It integrates seamlessly with water-reducing and set-retarding mother liquors to minimize concrete slump loss. Alternatively, amalgamate it with functional aids to develop admixtures featuring retarder, early strength, antifreeze, or pumping capabilities. Testing and compounding methodology should guide application modes and conditions.
4. BT-302 is compatible with other admixtures such as early strength agents, air-entraining agents, and retarders. Ensure compatibility through testing before use. Avoid mixing with naphthalene series water reducers.
5. Concrete cement and mix ratios should be defined by testing. During use, incorporate the measured and mixed water into the concrete mixer simultaneously, following mixing tests to ensure concrete quality.
6. When introducing active admixtures like fly ash and slag, compute the water-reducing agent amount as a percentage of the total cementing material weight.
