BT-302, a groundbreaking slump-retention superplasticizer that leverages state-of-the-art technology for fast-release and sustained performance. Crafted meticulously from TPEG via advanced free radical polymerization, BT-302 incorporates a novel, sustained-release mechanism that activates in the alkaline milieu of concrete. This slow-releasing molecular feature systematically dispenses dispersive groups, maintaining superior cement dispersion, significantly curtailing slump loss. Although BT-302 exhibits a modest water reduction rate, its unparalleled slump retention capabilities are unmatched. Ideal when paired with water-reducing mother liquors like JS-101B and JS-101A, BT-302 shines in high-strength concrete settings demanding extraordinary slump preservation. Its versatility spans a spectrum of engineering feats, from pumping concrete to super-flow self-compacting varieties, high-strength high-performance mixes, and the commercial concretes that support the robust frameworks of high-speed railways, expressways, hydro-power stations, and expansive engineering endeavors.
2. Benefit from unsurpassed slump performance, allowing concrete to preserve its slump for an extraordinary 2 hours without any loss.
3. Despite its low water reduction trait necessitating combination with water-reduction-type mother liquor, the superior execution is evident.
4. With its low viscosity and thixotropy, BT-302 is ideally crafted for concrete mixes featuring a low water-cement ratio.

2. BT-302 finds widespread application across high-speed railways, nuclear power facilities, water conservancy projects, subways, monumental bridges, expressways, harbors, and wharves, establishing itself as fundamental for national-scale and pivotal projects.
3. Perfectly suited for a multitude of industrial and civil construction projects, alongside commercial concrete mixing stations, BT-302's adaptability knows no bounds.
1. Presented as a colorless or light yellow liquid, BT-302 is typically used at a 0-20% concentration in synergy with a water-reducing mother liquor. Augment with small materials to formulate a water-reducing agent, typically comprising 1% to 3% of the total weight of cementing material for optimal performance.
2. Prior to BT-302 application, or when modifying cement and gravel types or batches, conduct adaptability tests to determine precise compatibility, guiding the formulation of an optimal water-reducing agent proportion.
3. While BT-302 can be employed independently, it is often recommended to combine it with water-reducing and set-retarding mother liquors to significantly minimize slump loss. Alternatively, integrate with functional aids to concoct admixtures featuring retardant, early strength, antifreeze, or pumping capabilities. Testing and expert compounding should steer application methods and conditions.
4. BT-302 seamlessly integrates with other admixtures like early strength agents, air-entraining agents, and retarders. Compatibility testing is crucial prior to use. Avoid mixing with naphthalene series water reducers to maintain effectiveness.
5. Determining concrete cement and mix ratios through testing is key. Upon use, mix the combined and measured water with the concrete mixer simultaneously, following mixing tests to ensure optimal concrete quality.
6. When active admixtures such as fly ash and slag are incorporated, calculate the water-reducing agent quantity as a percentage of total cementing material weight to maintain precise consistency.
