Introducing BT-302 Polycarboxylate Superplasticizer: Revolutionizing concrete mixture performance with advanced chemistry.
Experience unparalleled High Slump Retention with our Solid 50% formula - the ideal choice for demanding construction environments.
Product Introduction: Unlock the potential of your concrete projects with our innovative solutions.
BT-302 represents a leap in concrete technology with its fast-releasing capabilities and innovative slump retention mother liquor derived from TPEG, harnessing the power of free radical polymerization and integrating a novel sustained-release group, raising the bar for concrete performance. In alkaline concrete conditions, the slow-release group within this product's molecular framework gradually releases dispersive agents, effectively maintaining cement dispersion to significantly curb concrete slump loss. It boasts a modest water reduction rate, yet delivers exceptional slump protection, ensuring superior concrete performance. Typically combined with water-reducing mother liquor, this product excels in high-strength concrete applications demanding optimal slump protection. Primarily deployed in high-performance scenarios such as pumping concrete, super-flow self-compacting concrete, high-strength concrete, and commercial concrete for mega projects including high-speed railways, expressways, and hydropower constructions.
Main Features:
*Our slow-release mother liquor outpaces conventional PCE mother liquors, providing a gradual release effect.
Release typically occurs post 30 minutes, though this may vary depending on the materials used.
*Exhibits superior slump performance, maintaining concrete workability for up to 2 hours without slump loss.
*Although it has a low water reduction rate, it is recommended to be used in conjunction with a water-reducing mother liquor for optimal results.
*Featuring low viscosity and thixotropy, it is ideal for concrete applications with a low water-cement ratio.

Applications:
1. Suitable for an array of concrete configurations: early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, and high-performance concrete. Ideal for premixed cast-in-place concrete in industrial and civil structures, especially targeted at low-grade commercial concrete.
2. Perfectly suited for large-scale and key national projects, including high-speed railways, nuclear power plants, water conservancy and hydropower projects, subways, large bridges, expressways, and harbor developments.
3. Tailored for diverse industrial and civil construction environments and commercial concrete mixing stations.
Usage Guidelines:
1. Presented as a colorless or faintly yellow liquid. Dosage: Typically,combine 0-30% of this mother liquor with a water-reducing mother liquor, along with other minor materials, to formulate a water-reducing agent. The total dosage usually accounts for 1% to 3% of the total weight of cementing materials.
2.Conduct compatibility tests with cement and gravel prior to usage or when altering cement, gravel type, or batches. Based on these tests, set the water-reducing agent's formulation.
3.While this product can be utilized independently (though usually not recommended alone), it is often combined with water-reducing mother liquor to enhance functionality and performance. Achieve extended workability with Set Retarding capabilities. Utilize our superior mother liquor to significantly reduce concrete slump loss. Enhance its performance by compounding with functional additives to create versatile admixtures featuring retarding, early strength, antifreeze, and pumping functions.Utilize our products for maximum efficiency. The application methods and conditions should be fine-tuned through rigorous testing and innovative compounding technology.Ensure optimal results with our tailored approach.
4.This product seamlessly integrates with a variety of admixtures, including early strength agents, air entrainment agents, and retarders. Note: Thorough testing is advisable prior to use. Avoid mixing with naphthalene series water reducers for best results.
5.Concrete cement and mix ratios must be confirmed by tests. During usage, blend with mixed water or add simultaneously to the concrete mixer. Conduct a preliminary mixing test to guarantee the concrete's quality.Ensure excellence in every batch.
6.Incorporate active admixtures such as fly ash and slag by calculating the water-reducing agent's amount based on the total cementitious materials.
