BT-302 Polycarboxylate Superplasticizer
High Slump Retention Solid 50%
Product Introduction
BT-302 represents the forefront of innovation in superplasticizer technology, being a new generation product that excels in rapid release and impressive slump retention mother liquor, meticulously crafted from TPEG through state-of-the-art free radical polymerization, with an innovative sustained-release group ingeniously integrated into its synthesis. In the alkaline environment of concrete, this product's molecular structure ingeniously releases dispersion-empowered groups gradually. This continuous action enhances cement dispersion, effectively mitigating concrete slump loss. It offers a moderate water reduction rate, yet it boasts exceptional slump protection capabilities.Typically paired with water-reducing mother liquor, it is primarily tailored for high-strength concrete demanding superior slump protection, seamlessly integrating into applications like pumping concrete, ultra-flow self-compacting, high-strength high-performance concrete, and commercial concrete suitable for high-speed railway, expressway, hydro-power, and other ambitious engineering marvels.
Main Feature
*The innovative slow-release mother liquor sets a new precedent as a faster-release PCE mother liquor.
Optimal release generally occurs around 30 minutes, adaptable to material-specific differences.
*With unparalleled slump performance, ensuring concrete slump retention for up to 2 hours without degradation.
*The low water reduction rate necessitates combination with water-reducing mother liquor for optimal performance.
*Characterized by low viscosity and thixotropy, ideally suited for concrete with lower water-cement ratios.

Application
1. Perfect for formulating early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concrete. Versatile for all industrial and civil buildings in premixed cast-in-place concrete, especially low-grade commercial concrete.
2. Ideally suited for high-speed railways, nuclear power, water conservancy, hydro-power projects, subways, large bridges, expressways, harbors, and national key projects.
3. Widely applicable for industrial and civil construction and commercial concrete mixing stations.
How to Use
1. This product is available as a colorless or light yellow liquid. Dosage: Typically, utilize 0-30% mother liquor in combination with water-reducing mother liquor, blending other minor components to formulate the water-reducing agent. The typical dosage of water-reducing agent ranges between 1% and 3% of the total weight of cementitious materials.
2.Prior to using this product or when changing cement and gravel type or batch, it is crucial to conduct an adaptability test with cement and gravel. Post-test, determine the appropriate water-reducing agent proportion
3.This product can be used individually (though typically not recommended for standalone use) Unleash the potential of your construction projects with our Polycarboxylate Superplasticizer Liquid, designed to harmonize perfectly with water-reducing mother liquor. Its set retarding capabilities combine seamlessly with mother liquor to dramatically reduce concrete slump loss. Elevate your concrete mix by compounding with specialized functional aids to craft admixtures that boast retarder, early strength, antifreeze, and pumping functionalities, tailored for your project's needs.. For optimal performance, determine application methods and conditions through testing and advanced compounding technology..
4.This versatile product integrates seamlessly with other admixtures, such as early strength agents, air entrainment agents, and retarders. Ensure compatibility with tests before use, avoiding any mix with naphthalene series water reducers.
5.In concrete formulations, cement type and mix ratio should be precisely determined by testing. During use, add mixed and measured water simultaneously in the concrete mixer to guarantee superior concrete quality.e
6.When utilizing active admixtures like fly ash and slag, calculate the water-reducing agent proportion based on the total cementitious materials for accurate results.
