BT-302 Superplasticizer Liquid, a pinnacle of modern chemical engineering designed to elevate your concrete formulations. This state-of-the-art mother liquor is crafted using TPEG through advanced free radical polymerization techniques, featuring an ingenious sustained-release group that performs exceptionally in alkaline environments typical of concrete. As the slow-releasing group within BT-302's molecular structure gradually activates, it unleashes a powerful dispersive function that ensures prolonged cement dispersion, effectively curbing concrete slump loss. While its water reduction capability is modest, its slump protection prowess is unparalleled. Ideally used alongside water-reducing mother liquors like JS-101B and JS-101A, BT-302 is particularly beneficial for high-strength concrete where outstanding slump protection is paramount. Its versatility makes it indispensable for engineering feats such as pumping concrete, super-flow self-compacting concrete, and high-strength, high-performance concrete. It is a trusted choice for commercial concrete applications in high-speed railways, expressways, hydro-power stations, and other monumental engineering endeavors.
2. Revel in unmatched slump retention, with BT-302 enabling concrete to maintain its slump for an extraordinary 2 hours without any decline.
3. Though it exhibits a lower water reduction rate, pairing BT-302 with water-reducing mother liquor delivers outstanding results.
4. With its low viscosity and thixotropic nature, BT-302 is flawlessly tailored for concrete mixes with a low water-cement ratio.

2. Widely employed in high-speed railways, nuclear power plants, water conservancy projects, subways, and large bridges, BT-302 is a critical component in national large-scale projects, standing as a pillar of excellence in expressways, harbors, and wharves.
3. Its versatility extends to a multitude of industrial and civil construction projects as well as commercial concrete mixing stations, showcasing its unmatched adaptability and performance.
1. The product is a colorless or light yellow liquid. For optimal results, use 0-20% mother liquor along with a water-reducing mother liquor. Additionally, combine with other minor materials to formulate a water-reducing agent, typically comprising 1% to 3% of the total cementitious material weight.
2. Conduct adaptability tests with specific cement and gravel before using BT-302 or changing cement and gravel types and batches. Utilize test results to craft an optimal water-reducing agent proportioning.
3. While BT-302 can be used alone, it is often more effective when combined with water-reducing and set-retarding mother liquors to mitigate slump loss. Alternatively, blend with functional aids to create admixtures with retarder, early strength, antifreeze, or pumping enhancements. Rely on testing and compounding technology to guide application methods.
4. BT-302 integrates harmoniously with other admixtures such as early strength agents, air-entraining agents, and retarders. Compatibility testing is essential before use. Avoid mixing with naphthalene series water reducers to maintain product integrity.
5. Establish concrete cement and mix ratios through rigorous testing. During application, add the mixed and measured water to the concrete mixer simultaneously, ensuring high-quality results through thorough mixing tests.
6. When using active admixtures like fly ash and slag, calculate the water-reducing agent dosage as a percentage of the total cementitious material weight to achieve precise and effective outcomes.
