BT-302 is a revolutionary, fast-releasing, and slump-retaining mother liquor crafted from TPEG through advanced free radical polymerization. This groundbreaking product integrates a novel sustained-release group into its formulation. Within the alkaline environment of concrete, BT-302's molecular structure gradually liberates its dispersive function group, effectively sustaining cement dispersion and significantly reducing concrete slump loss. Although BT-302 has a lower water reduction rate, its unparalleled slump protection performance stands unrivaled. It is typically paired with water-reducing mother liquors like JS-101B and JS-101A. BT-302 is especially advantageous in high-strength concrete applications where superior slump protection is crucial. It is indispensable in various engineering marvels, from pumping concrete, super-flow self-compacting concrete, and high-strength high-performance concrete to commercial concrete for high-speed railways, expressways, hydro-power stations, and other monumental projects.
2. Revel in unmatched slump performance, allowing concrete to maintain its slump for an extraordinary 2 hours without any loss.
3. While the low water reduction rate calls for combination with water-reduction-type mother liquor, the results are remarkably effective.
4. With low viscosity and thixotropy, BT-302 is perfectly optimized for concrete with a low water-cement ratio.

2. BT-302 is extensively applied in high-speed railways, nuclear power plants, water conservancy projects, subways, large bridges, expressways, harbors, and wharves. It is indispensable for national large-scale and key projects.
3. BT-302 is ideal for a multitude of industrial and civil construction projects, as well as commercial concrete mixing stations. Its versatility knows no bounds.
1. BT-302 is a colorless or light yellow liquid. Typically, use 0-20% mother liquor in combination with a water-reducing mother liquor. Additionally, blend with other small materials to create a water-reducing agent. The dosage generally constitutes 1% to 3% of the total cementing material weight.
2. Before utilizing BT-302 or changing the type and batch of cement and gravel, it's essential to conduct adaptability testing with the specific cement and gravel. Based on test outcomes, formulate an optimal proportion for the water-reducing agent.
3. While BT-302 can be used singly, it's often not recommended. It seamlessly combines with water-reducing and set-retarding mother liquors to minimize concrete slump loss. Alternatively, pair it with functional aids to develop admixtures with retarder, early strength, antifreeze, or pumping capabilities. Testing and compounding technology should guide application methods and conditions.
4. BT-302 harmonizes with other admixtures such as early strength agents, air-entraining agents, and retarders. Ensure compatibility through testing prior to use and avoid mixing with naphthalene series water reducers.
5. Concrete cement and mix ratios should be determined by testing. During use, integrate the mixed and measured water into the concrete mixer concurrently, following mixing tests to ensure concrete quality.
6. When incorporating active admixtures like fly ash and slag, calculate the water-reducing agent amount as a percentage of the total cementing material weight.
