Introducing BT-302, an avant-garde solution in the realm of concrete admixtures. This fast-releasing and slump-retaining mother liquor is meticulously crafted from TPEG through advanced free radical polymerization processes. Elevating its innovation, BT-302 integrates a novel sustained-release group within its molecular framework. In the highly alkaline environment of concrete, this slow-releasing group gradually unfolds a dispersive function group, ensuring continuous cement dispersion. This mechanism significantly curtails concrete slump loss. Despite its modest water reduction rate, BT-302's unparalleled slump protection is unmatched. Typically employed alongside water-reducing mother liquors such as JS-101B and JS-101A, BT-302 is a game-changer for high-strength concrete applications demanding top-tier slump safeguarding. It excels in a myriad of engineering wonders, from pumping concrete and super-flow self-compacting concrete to high-strength high-performance concrete. It is also ideal for commercial concrete used in high-speed railways, expressways, hydro-power stations, and other monumental engineering feats.
2. This product showcases unrivaled slump performance, allowing concrete to maintain its slump for an extraordinary duration of 2 hours without any loss.
3. Despite its low water reduction rate necessitating combination with water-reduction-type mother liquors, the outcomes are exceptionally impressive and highly beneficial.
4. With its low viscosity and thixotropy, BT-302 is ideally suited for concrete with a low water-cement ratio, ensuring optimal performance.

2. With extensive applications in high-speed railways, nuclear power plants, water conservancy projects, subways, large bridges, expressways, harbors, and wharves, BT-302 is indispensable for national large-scale and key engineering projects.
3. BT-302 is ideal for an array of industrial and civil construction projects, as well as commercial concrete mixing stations, exhibiting unparalleled versatility.
1. BT-302 presents as a colorless or light yellow liquid. Typically, incorporate 0-20% mother liquor with a water-reducing mother liquor. It can also be blended with other minor materials to formulate a water-reducing agent. The water-reducing agent dosage generally constitutes 1% to 3% of the total cementing material weight.
2. Prior to employing BT-302 or when varying the type and batch of cement and gravel, it is crucial to conduct adaptability testing with specific cement and gravel. Based on test outcomes, determine the optimal proportion for the water-reducing agent.
3. While BT-302 can function independently, it is often recommended to combine it with water-reducing and set-retarding mother liquors to minimize concrete slump loss. Alternatively, it can be paired with functional aids to create admixtures with enhanced properties such as retardation, early strength, antifreeze, or pumping capabilities. Application methods and conditions should be guided by testing and compounding technology.
4. BT-302 integrates harmoniously with other admixtures such as early strength agents, air-entraining agents, and retarders. Ensure compatibility through prior testing. Avoid mixing with naphthalene series water reducers.
5. Concrete cement and mix ratios should be established based on thorough testing. During use, incorporate the mixed and measured water into the concrete mixer simultaneously, following mixing tests to ensure concrete quality.
6. When introducing active admixtures like fly ash and slag, calculate the water-reducing agent amount as a percentage of the total cementing material weight.
