BT-302 is a revolutionary, high-performance, fast-releasing superplasticizer to maintain concrete excellence. Crafted using TPEG and advanced free radical polymerization, BT-302 integrates a novel sustained-release group that gradually liberates dispersive functions in alkaline environments. This mechanism effectively preserves cement dispersion, significantly reducing concrete slump loss. While the water reduction rate is modest, the outstanding slump protection is unparalleled. BT-302 is especially formulated for synergy with water-reducing mother liquors like JS-101B and JS-101A, suiting it perfectly for high-strength concrete that requires superior slump preservation. Ideal for numerous engineering feats, BT-302 excels in pumping and super-flow self-compacting concrete, as well as high-strength, high-performance mixtures. It is a cornerstone for projects like high-speed railways, expressways, hydro-power stations, and other grand engineering ventures.
2. Benefit from outstanding slump retention performance, allowing concrete to maintain its slump for an extraordinary 2 hours without degradation.
3. Although it boasts a low water reduction rate, when combined with a water-reduction-type mother liquor, the synergistic results are remarkable.
4. With its low viscosity and thixotropic properties, BT-302 is perfectly tailored for concrete mixes with a low water-cement ratio.

2. BT-302 is a key player in high-speed railways, nuclear power plants, water conservancy projects, subways, large bridges, expressways, harbors, and wharves, making it an indispensable choice for national large-scale and pivotal projects.
3. Its exceptional versatility makes BT-302 ideal for a wide spectrum of industrial, civil construction projects, and commercial concrete mixing stations.
1. This colorless or light yellow liquid is typically used as a 0-20% mother liquor in combination with a water-reducing mother liquor. It can be blended with other materials to create a water-reducing agent, which usually comprises 1% to 3% of the total cementing material weight.
2. Before employing BT-302 or changing cement and gravel types and batches, adaptability testing with specific materials is essential. The test results will guide the optimal formulation of the water-reducing agent.
3. Although BT-302 can be used independently, it is often recommended to combine it with water-reducing and set-retarding mother liquors to minimize slump loss. Alternatively, pair it with functional aids to develop admixtures with retarder, early strength, antifreeze, or pumping capabilities. Application methods and conditions should be determined by testing and compounding technology.
4. BT-302 is compatible with other admixtures like early strength agents, air-entraining agents, and retarders. Conduct compatibility testing before use and avoid mixing with naphthalene series water reducers.
5. Define concrete cement and mix ratios through testing. During use, integrate mixed and measured water into the concrete mixer concurrently, following mixing tests to ensure concrete quality.
6. When incorporating active admixtures such as fly ash and slag, calculate the water-reducing agent as a percentage of the total cementing material weight.
