Introducing the Advanced BT-302 Superplasticizer, a remarkable light yellow liquid formulation. Crafted through sophisticated free radical polymerization of TPEG, this fast-releasing, slump-retaining mother liquor is a marvel of modern engineering. It features an innovative slow-release group that, in the alkaline environment of concrete, liberates a dispersive function group, ensuring outstanding cement dispersion and significantly inhibiting concrete slump loss. While the water reduction rate is low, BT-302's unrivaled slump protection places it in a class of its own. It is typically paired with water-reducing substances like JS-101B and JS-101A, and is indispensable for high-strength concrete applications where exceptional slump protection is paramount. BT-302 is a cornerstone in numerous engineering triumphs, from pumping concrete and super-flow self-compacting concrete to high-strength high-performance concrete and commercial concrete used in high-speed railways, expressways, hydro-power stations, and other monumental engineering projects.
2. Benefit from unparalleled slump performance, with concrete retaining its slump for an astounding 2 hours without any degradation.
3. Although its water reduction rate is modest, when combined with a water-reduction-type mother liquor, the effectiveness is unmistakable.
4. Its low viscosity and thixotropic properties make BT-302 ideal for concrete with a low water-cement ratio.

2. BT-302 is extensively utilized in high-speed railways, nuclear power plants, water conservancy projects, subways, large bridges, expressways, harbors, and wharves. It is a crucial component for national large-scale and key projects.
3. Perfect for a wide spectrum of industrial and civil construction undertakings, as well as commercial concrete mixing stations, its versatility is boundless.
1. This product is a colorless to light yellow liquid. Typically, use between 0-20% mother liquor alongside a water-reducing mother liquor. Combine with other small materials to create a water-reducing agent, with the dosage typically representing 1% to 3% of the total cementing material weight.
2. Before using BT-302 or altering the type and batch of cement and gravel, conducting adaptability testing with the specific cement and gravel is crucial. Utilize test outcomes to determine the optimal proportion for the water-reducing agent.
3. While BT-302 can be used on its own, it is often recommended to blend it with water-reducing and set-retarding mother liquors to diminish concrete slump loss. Alternatively, combine it with functional aids to create admixtures with retarder, early strength, antifreeze, or pumping capabilities. The application methods and conditions should be guided by testing and compounding technology.
4. BT-302 works in harmony with other admixtures like early strength agents, air-entraining agents, and retarders. Ensure compatibility through prior testing. Avoid combining it with naphthalene series water reducers.
5. Concrete cement and mix ratios should be established through testing. During application, integrate the mixed and measured water into the concrete mixer at the same time to ensure the quality of the concrete after performing mixing tests.
6. When incorporating active admixtures such as fly ash and slag, calculate the water-reducing agent quantity as a percentage of the total cementing material weight.
