Introducing BT-302, a revolutionary, fast-acting, and slump-enhancing superplasticizer! Synthesized with cutting-edge TPEG and advanced radical polymerization, this liquid marvel is expertly formulated for groundbreaking performance. The innovative sustained-release group within BT-302 ensures a gradual liberation of dispersion-enhancing agents within concrete's alkaline environment, significantly curbing slump loss. While featuring a modest water reduction rate, BT-302 offers unparalleled slump retention, making it ideal for high-strength concrete projects. Perfectly complementing water-reducing liquors like JS-101B and JS-101A, BT-302 shines in a spectrum of high-performance applications, from pumping concrete to super-flow self-compacting creations. Whether crafting commercial concrete for high-speed railways, expressways, or grand-scale hydro-power installations, BT-302 is your trusty ally for superior slump protection and beyond.
2. Experience unrivaled slump retention! Ensure your concrete maintains its slump for an impressive duration of up to 2 hours with no loss.
3. Although necessitating a combination with water-reducing liquors due to its low water reduction rate, the resulting performance is simply extraordinary.
4. With its low viscosity and thixotropic properties, BT-302 is the perfect match for concrete with a reduced water-cement ratio.

2. BT-302 is a vital component in high-profile projects like high-speed railways, nuclear power plants, water conservancy efforts, subways, monumental bridges, expressways, harbors, and wharves. Its role is indispensable in national large-scale and pivotal projects.
3. From industrial to civil construction endeavors and commercial concrete mixing stations, BT-302's versatility is unmatched, making it an essential asset for diverse construction demands.
1. BT-302 presents as a colorless or light yellow liquid. Typically, mix 0-20% mother liquor with a water-reducing mother liquor. Combine additional materials to devise a tailored water-reducing agent, with dosages generally making up 1% to 3% of total cementing material weight.
2. Prior to BT-302 application, or when changing cement and gravel types or batches, conduct adaptability tests. Utilize test results to establish the optimal water-reducing agent proportion for exceptional results.
3. Although BT-302 can be used standalone, it's often best combined with water-reducing and set-retarding liquors for optimal slump conservation. Alternatively, pair with functional aids to create admixtures with specialized features like retarders or early strength. Let testing guide application methods and conditions.
4. BT-302 harmonizes beautifully with admixtures like early strength agents, air-entraining agents, and retarders. Ensure pre-use testing for compatibility, and avoid mixing with naphthalene series water reducers.
5. Define concrete cement and mix ratios through comprehensive testing. During application, introduce mixed and measured water to the concrete mixer concurrently, ensuring thorough mixing for quality assurance.
6. When using active admixtures such as fly ash or slag, calculate the water-reducing agent's inclusion as a percentage of the total cementing material weight for precise formulation.
