Introducing the BT-302, a revolutionary and fast-releasing mother liquor designed for unparalleled slump retention. Expertly crafted through advanced TPEG radical polymerization, this state-of-the-art product introduces a novel sustained-release group, ensuring optimal cement dispersion in concrete's alkaline environment. As BT-302's molecular structure gradually releases a dispersive group, it effectively curtails concrete slump loss, delivering exceptional slump protection unmatched by others. Although it exhibits a modest water reduction rate, its superior slump retention capabilities make it indispensable, particularly when paired with JS-101B and JS-101A water-reducing liquors. BT-302 shines in high-strength concrete applications that demand outstanding slump preservation, making it an essential choice for engineering marvels like pumping concrete, super-flow self-compacting concrete, high-strength high-performance concrete, and commercial concrete tailored for high-speed railways, expressways, hydro-power stations, and grand engineering projects.
2. Experience unrivaled slump performance, ensuring concrete retains its slump for an impressive 2 hours with no loss.
3. Despite its low water reduction rate necessitating a blend with water-reduction-type mother liquors, the outcomes are nothing short of extraordinary.
4. With low viscosity and thixotropy, BT-302 is exceptionally suited for concrete with a low water-cement ratio, ensuring optimal performance.

2. BT-302 is indispensable for national large-scale projects, finding extensive applications in high-speed railways, nuclear power plants, water conservancy projects, subways, large bridges, expressways, harbors, and wharves.
3. Ideal across a multitude of industrial and civil construction projects, as well as commercial concrete mixing stations, BT-302 offers unmatched versatility.
1. Presented as a colorless or light yellow liquid, this product typically combines 0-20% mother liquor with a water-reducing mother liquor. Additionally, mix with other components to create a water-reducing agent, generally constituting 1% to 3% of the total cementing material weight.
2. Prior to using BT-302 or changing cement and gravel types, conduct adaptability testing to determine the best water-reducing agent proportion based on test results.
3. Though BT-302 can be used alone, it is often best combined with water-reducing and set-retarding mother liquors to minimize concrete slump loss. Alternatively, it can pair with functional aids to develop admixtures with retarder, early strength, antifreeze, or pumping capabilities. Testing and technology should guide application methods and conditions.
4. BT-302 is compatible with admixtures like early strength agents, air-entraining agents, and retarders. Ensure compatibility through testing before use. Avoid mixing with naphthalene series water reducers.
5. Concrete cement and mix ratios should be determined through testing. During use, integrate the mixed and measured water into the concrete mixer simultaneously, ensuring quality through mixing tests.
6. When using active admixtures like fly ash and slag, calculate the water-reducing agent as a percentage of the total cementing material weight.
