Introducing BT-302, the pinnacle of superplasticizer innovation, a trailblazing liquid developed from TPEG through advanced free radical polymerization. This extraordinary product boasts a novel sustained-release group, specifically crafted to enhance concrete stability. Within the alkaline ambience of concrete, BT-302's groundbreaking slow-releasing group gradually deploys a dispersive function, ensuring optimal cement dispersion and effectively mitigating slump loss. While its water reduction rate may be modest, BT-302 excels in unmatched slump protection. Typically paired with water-reducing agents such as JS-101B and JS-101A, BT-302 is the go-to solution for high-strength concrete applications necessitating exceptional slump retention. Its versatile application spans across various engineering feats, including pumping concrete, super-flow self-compacting concrete, and high-strength high-performance concrete, making it indispensable in commercial concrete ventures for high-speed railways, expressways, hydro-power stations, and more.
2. Revel in unmatched slump preservation, where concrete astonishingly retains its slump integrity for a remarkable 2 hours, without any loss.
3. While its water reduction rate is low, necessitating a combination with a water-reducing mother liquor, the amalgamation yields extraordinary outcomes.
4. Its low viscosity and thixotropic nature render BT-302 exceptionally suitable for concrete systems with a low water-cement ratio.

2. BT-302 shines in high-speed railways, nuclear power stations, water conservancy projects, subways, large bridges, expressways, harbors, and wharves, making it a cornerstone for monumental national projects.
3. Ideal for diverse industrial and civil construction ventures, as well as commercial concrete mixing stations. Its limitless versatility is unmatched.
1. This marvel is a colorless or light yellow liquid. Typically, use 0-20% of it as a mother liquor in conjunction with a water-reducing agent. Blend with other materials to create a powerful water-reducing agent, with its dosage usually forming 1% to 3% of the total cementing material weight.
2. Prior to employing BT-302 or switching cement and gravel types and batches, conduct adaptability tests with the specific materials. Based on results, formulate an optimal ratio for the water-reducing agent.
3. Although BT-302 can be utilized independently, it's not often recommended. It integrates flawlessly with water-reducing and set-retarding agents to minimize slump loss. Alternatively, pair it with functional aids to craft admixtures offering retarder, early strength, antifreeze, or pumping capabilities. Testing and compounding technology should guide application methods and conditions.
4. BT-302 blends harmoniously with other admixtures such as early strength, air-entraining agents, and retarders. Ensure compatibility through pre-use testing. Avoid combining with naphthalene series reducers.
5. Define concrete cement and mix ratios through testing. During application, incorporate the measured water alongside the concrete mix, following mixing tests to assure quality.
6. When integrating active admixtures like fly ash and slag, calculate the water-reducing agent amount based on the total cementing material weight.
