Introducing BT-302 Polycarboxylate Superplasticizer: A marvel of modern chemical engineering, this product stands at the forefront of concrete technology.
Crafted for Excellence: Featuring High Slump Retention with a robust 50% solid content, ensuring superior performance in demanding conditions.
Product Introduction: Unveiling a next-generation solution designed to revolutionize concrete mixtures.
BT-302 is a groundbreaking new generation of fast-releasing technology that excels in retaining slump, acting as a powerful mother liquor derived from TPEG. Engineered through free radical polymerization, a pioneering sustained-release group enhances synthesis,ensuring superior concrete performance. In the alkaline realm of concrete, the innovative slow-releasing group within this product's molecular structure meticulously releases its dispersive elements, continuously dispersing cement, thereby effectively inhibiting concrete slump loss.This innovative product boasts a modest water reduction rate, while delivering unparalleled slump protection performance.This balance ensures optimal performance.Ideal for use with water-reducing mother liquor, this product is engineered for high-strength concrete where superior slump protection is paramount. Its applications range across pumping concrete, self-compacting, high-performance concrete, and commercial concrete for grand-scale projects like high-speed railways, expressways, and hydro-power engineering feats.Ideal for large-scale engineering marvels.
Main Feature: Discover the pioneering attributes of this advanced superplasticizer.

3. Suitable for diverse industrial, civil constructions, and commercial concrete mixing stations.
How to Use: Simple guidelines for optimal results.
1. This product is presented as a colorless or light yellow liquid, ensuring ease of integration. Dosage: Typically,utilize 0-30% of mother liquor in conjunction with water-reducing mother liquor and integrate other small materials to craft a water-reducing agent. The agent's dosage ranges from 1% to 3% relative to the total weight of cementingmaterials, ensuring efficiency. 2. Before deploying this product or varying the cement and gravel types and batches, it is crucial to conduct adaptability tests with these materials. Formulate the water-reducing agent proportion based on test outcomes.
2. Precise adaptation is key.3. Deploy this product either singularly (though typically not recommended) or in combination with water-reducing mother liquor for enhanced performance.
3. Flexible in application.Use this product as an independent agent (though typically not advised for solo use), or combine it with water-reducing mother liquor for synergistic effects in concrete applications. Set Retarding: A crucial process that ensures your concrete retains its workability and doesn't set too quickly, allowing more time for adjustments and application. Mother Liquor for Reduced Concrete Slump Loss: Engineered to minimize slump loss in concrete, this base component can be seamlessly compounded with specialized functional aids. Functional Aids: These are the enhancers that transform your concrete mix into a robust solution with added benefits. to achieve admixtures with tailored properties such as retarder, early strength, antifreeze, and enhanced pumping capabilities.. Application Method & Conditions: The approach and environment for utilizing this product must be determined through rigorous testing and advanced compounding technology..
4.Compatibility: This innovative product can be integrated with various admixtures like early strength agents, air entrainment agents, and retarders. It's essential to conduct preliminary tests before use and avoid mixing with naphthalene series water reducers.
5.Concrete Optimization: The cement and mix ratio must be customized through testing. During application, ensure that the mixed and measured water is added simultaneously to the concrete mixer. Conduct a mixing test beforehand to guarantee superior concrete quality.e
6.Active Admixtures Consideration: When incorporating elements like fly ash and slag, calculate the water-reducing agent based on the total cementing materials to ensure optimal performance.
