Product Description
BT-302 Polycarboxylate Superplasticizer: Unleash the Future of Concrete Solutions
High Slump Retention Solid 50%: Ensuring Optimal Concrete Fluidity and Durability
High Slump Retention Solid 50%: Ensuring Optimal Concrete Fluidity and Durability
Product Introduction: Welcome to the Next Generation of Concrete Mix Innovation
BT-302 is a revolutionary fast-releasing and slump-retaining mother liquor crafted from TPEG through advanced free radical polymerization. A novel sustained-release group is seamlessly integrated into its synthesis. In the alkaline environment of concrete, this product's slow-releasing group liberates a dispersive-function group gradually, effectively continuing to disperse the cement, achieving impressive inhibition of concrete slump loss. It boasts a low water reduction rate, yet delivers exceptionally high performance in slump protection.Ideal for use with water-reducing mother liquor, it excels in high-strength concrete applications that demand superior slump protection. Its versatility shines in pumping concrete, super-fluid self-compacting, and high-performance concrete applications, along with commercial concrete for ambitious projects like high-speed railways, expressways, and large hydro-power constructions and other extensive engineering endeavors.
Main Features
* The slow-release mother liquor transitions into a faster-releasing PCE mother liquor.
The typical release timeframe starts at 30 minutes (varying based on material differences)
* Boasting an ultra-high slump performance, it maintains concrete slump integrity for up to 2 hours without any loss
* Given its low water reduction rate, it is typically not used on its own and should be combined with water-reduction mother liquor
* With its low viscosity and thixotropy, it's the perfect choice for concrete with a low water-cement ratio

Instructions for Use
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 materials to create a water-reducing agent. The recommended dosage of this water-reducing agent is 1% to 3% of the total cementing materials' weight.
2.Before utilizing this product or altering the type and batch of cement and gravel, conducting an adaptability test with cement and gravel is essential. Based on the results, formulate the water-reducing agent's proportion
3.This product can be utilized individually (though typically not recommended alone) and is best combined with water-reducing mother liquor for optimal results. Set Retarding: This feature ensures a slower hardening process, allowing for extended workability and flexibility during construction projects. Our mother liquor is expertly formulated to significantly reduce concrete slump loss, helping to maintain the fluidity and workability of your mixes. It can also be compounded with additional functional aids, leveraging the potential of cutting-edge technology to enhance performance and versatility. This enables the creation of admixtures with a range of specialized functions such as retarders, early strength enhancers, antifreeze properties, and pumping performance to suit various construction needs.. The application methods and conditions should be tailored through rigorous testing and cutting-edge compounding technology to ensure optimal results in every use case..
4.This remarkable product can be seamlessly integrated with other admixtures, including early strength agents, air entrainment agents, and retarders. Conduct a test prior to use for compatibility assurance. Note: Avoid mixing with naphthalene series water reducers.
5.Concrete The precise cement and mix ratio should be established through thorough testing. During use, combine the admixture with mixed and measured water, or introduce it simultaneously into the concrete mixer. Prior to application, execute a mixing test to confirm the concrete's quality.e
6.In concrete formulations containing active admixtures like fly ash and slag, calculate the water-reducing agent dosage based on the total volume of cementing materials to ensure consistency and effectiveness.
