BT-302 Polycarboxylate Superplasticizer: Revolutionizing Concrete Construction
High Slump Retention Solid 50%: Unmatched Concrete Stability
Product Introduction: Discover Innovative Concrete Solutions
BT-302 is a groundbreaking next-gen superplasticizer known for its rapid release. This product is renowned for its excellent slump retention capabilities. A mother liquor formulated from TPEG using advanced free radical polymerization technology. It introduces a novel sustained-release group enhancing the synthesis process.. In the alkaline environment of concrete, the innovative slow-releasing group within this product's molecular structure gradually releases a dispersive function group, continuously dispersing cement and effectively minimizing concrete slump loss.. It boasts a modest water reduction rate, whilst offering superior slump protection that is unparalleled..Optimal when paired with water-reducing mother liquor, this product is tailored for high-strength concrete demanding enhanced slump protection. BT-302 seamlessly integrates into applications such as pumping concrete, super-flow self-compacting, and high-strength, high-performance concrete. It excels in commercial concrete used for critical projects like high-speed railways, expressways, and hydro-power facilities, among other extensive engineering endeavors.
Main Features: Unveil the Excellence
* Our slow-release mother liquor surpasses the release speed of conventional PCE mother liquors.
Typically, release occurs after 30 minutes (depending on material-specific variations).
* Engineered to deliver exceptional slump performance, ensuring concrete slump remains stable for up to 2 hours without degradation.
* While the water reduction rate is moderate, it is recommended to combine with water-reducing mother liquor for optimal results.
* With its low viscosity and thixotropic properties, it is particularly well-suited for concrete with low water-cement ratios.

How to Use: Guide to Optimal Application
1. This product is available as a colorless or light yellow liquid. Dosage: Typically, use 0-30% mother liquor with water-reducing mother liquor, incorporating other minor components to prepare a water-reducing agent. The recommended dosage of the water-reducing agent is typically 1% to 3% of the total weight of cementing materials for effective results.
2.Prior to use, or when modifying the type or batch of cement and aggregate, it is crucial to conduct compatibility tests to determine the appropriate proportion of water-reducing agent based on test outcomes.
3.This product can be utilized on its own (though single use is not typically recommended). It can also be combined with water-reducing mother liquor for enhanced performance. This superior liquid formulation offers set retarding capabilities, ensuring optimal performance and longevity in concrete applications. Mother liquor is expertly crafted to significantly reduce concrete slump loss. It can be seamlessly compounded with functional aids to enhance and customize your concrete blends. Unlock the full potential of your concrete with admixtures that boast retarder, early strength, antifreeze, and pumping functions, tailored to meet your construction needs.. Application methods and conditions are best determined through rigorous testing and advanced compounding technology, ensuring precision and effectiveness in every use..
4.This versatile product is designed to work harmoniously with various admixtures, including early strength agents, air entrainment agents, and retarders, offering flexibility and enhanced performance. Prior testing is advised. Caution: Avoid mixing with naphthalene series water reducers.
5.Concrete cement and mix ratios must be meticulously determined through testing. During use, ensure mixed and measured water is simultaneously added to the concrete mixer. Conduct preliminary mixing tests to guarantee superior concrete quality.e
6.In scenarios where active admixtures like fly ash and slag are incorporated into the concrete mix, calculate the water-reducing agent based on the total cementitious materials for optimal results.
