BT-302 Polycarboxylate Superplasticizer High Slump Retention solid liquid
Introducing Our Premium Product
BT-302, the new generation of advanced superplasticizers, is designed for rapid release and superior slump retention. Its unmatched ability to retain slump sets it apart. This mother liquor is crafted from high-quality TPEG through state-of-the-art free radical polymerization, featuring a novel sustained-release group for enhanced performance. In alkaline concrete environments, the innovative slow-releasing group within the molecular structure gradually disperses, effectively mitigating concrete slump loss.This ensures an impressive low water reduction rate, while delivering exceptionally high slump protection, making it a preferred choice for demanding projects.Commonly paired with water-reducing mother liquor, it excels in high-strength concrete applications needing superior slump protection. Perfect for pumping concrete, super-flow self-compacting, high-strength, high-performance concrete, and commercial concrete used in high-speed railways, expressways, and large-scale engineering marvels.
Outstanding Features
*Experience the swift dissipation of slow-release mother liquor, outpacing traditional PCE formulations.
Release typically occurs after 30 minutes, with variations based on material properties.
*Boasting super high slump performance, maintaining concrete slump for 2 hours without degradation.
*The low water reduction rate necessitates its combination with water reduction mother liquor for optimal performance.
*Its low viscosity and thixotropy are ideal for concrete with low water-to-cement ratios.

Applications
1. Ideally suited for early-strength, retarded, precast, and cast-in-place concrete. Perfect for flow, self-compacting, mass, high-performance, and clear concrete across industrial and civil projects, especially low-grade commercial concrete.
2. Versatile applications include high-speed railways, nuclear plants, water conservancy, metro systems, large bridges, expressways, harbors, and major national projects.
3. An excellent choice for industrial, civil construction, and commercial concrete mixing stations.
Usage Instructions
1. This premium product is available as a colorless or light yellow liquid, ensuring purity. Dosage: Typically,use a 0-30% mother liquor blend with water-reducing mother liquor. Combine with minor materials for an effective water-reducing agent, typically 1% to 3% of total cementitious material weight.
2. Prior to use, or when changing cement and aggregate types or batches, conduct adaptability tests to fine-tune water-reducing agent proportions.
3.While this product can be used on its own, it is typically recommended to combine it with complementary agents for optimal efficacy. Effortlessly blend our Premium Polycarboxylate Superplasticizer Liquid with water-reducing mother liquor and add the perfect touch of elegance to your concrete mixes. set-retarding mother liquor to effectively minimize concrete slump loss. Alternatively, create a superb compound with functional aids to achieve a versatile admixture that includes remarkable properties such as retarder, early strength, antifreeze, and enhanced pumping capabilities. To achieve optimal results, the application method and conditions should be determined through rigorous testing and advanced compounding technology.
4.Our innovative product is designed for compatibility with a variety of admixtures including early strength agents, air entrainment agents, retarders, and more. Prior testing is essential to ensure compatibility. Please note: it must not be mixed with naphthalene series water reducers.
5.Concrete cement and mix ratios are crucial and should be precisely determined through comprehensive testing. During application, ensure that mixed and measured water is added simultaneously into the concrete mixer. Conduct initial mixing tests to guarantee superior concrete qualitye
6.In scenarios where active admixtures such as fly ash and slag are utilized in the concrete mix, calculate the water-reducing agent's requirement based on the total amount of cementitious materials.
