Introducing the BT-302 Polycarboxylate Superplasticizer
Experience Unmatched High Slump Retention with Solid 50% Formulation
Product Introduction Overview
BT-302 heralds a new era in superplasticizers, offering fast-releasing benefits and remarkable slump retention, crafted from premium TPEG through advanced free radical polymerization, incorporating an innovative sustained-release group for enhanced synthesis. In the alkaline environment of concrete, this product's unique slow-releasing group gradually disseminates a dispersive function, effectively maintaining cement dispersion to minimize concrete slump loss.Furthermore, it boasts a modest water reduction rate, while delivering exceptional slump protection performance.This makes it an ideal choice for high-strength concrete applications.Commonly paired with water reducing solutions, this product excels in high-strength concrete demanding superior slump retention. Its applications extend to pumping concrete, self-compacting super-flow concrete, and high-performance concrete, including commercial concrete for high-speed railways, expressways, and hydro-power, as well as other expansive engineering endeavors.
Main Feature Highlights
*The slow-release mother liquor surpasses the faster-releasing PCE mother liquor.
Typically, the release occurs 30 minutes post-application (varies depending on material specifics).
*Exhibits incredibly high slump performance, sustaining concrete slump for 2 hours with no loss.
*While its low water reduction rate suggests it is typically used in tandem with water-reducing mother liquor.
*Features low viscosity and thixotropy, making it particularly suitable for concrete with low water-cement ratios.

Instructions for Use
1. This product appears as a colorless or light yellow liquid. Dosage: Typically,incorporate 0-30% mother liquor with water-reducing solutions, blending with small additional materials to formulate the water-reducing agent. Generally, the dosage is 1% to 3% of the total weight ofcementing materials.
2. Conduct compatibility tests with cement and gravel before first use or when changing cement/gravel types and batches. Tailor the water-reducing agent proportion based on test outcomes.
3.While this product can be used standalone, typically, it is not advisable. Instead, combine it with water-reducing solutions for optimal performance. It harmonizes seamlessly with water-reducing mother liquor to maximize benefits and efficiency. Boasting advanced set retarding capabilities, this product ensures extended workability and increased efficiency for any construction project. Our superior mother liquor formulation is designed to significantly reduce concrete slump loss, providing consistency and reliability. Enhance its capabilities by compounding with functional aids, offering a bespoke solution tailored to your specific needs. Craft versatile admixtures with multi-functional attributes like retarder, early strength, antifreeze, and pumping functions, ensuring your construction material outperforms expectations.. To achieve optimal results, determine the precise application method and conditions through rigorous testing and advanced compounding technology..
4.This versatile product seamlessly integrates with various admixtures such as early strength agents, air-entrainment agents, and retarders. It is crucial to conduct thorough testing prior to use. Note: Avoid mixing with naphthalene series water reducers to maintain integrity.
5.Selection of an appropriate concrete cement and mix ratio should be determined through meticulous testing. During application, ensure mixed and measured water is simultaneously incorporated into the concrete mixer. Conduct a mixing test in advance to guarantee superior concrete quality.e
6.Incorporating active admixtures like fly ash and slag requires precise calculation of the water-reducing agent, based on the overall amount of cementing materials, for optimal performance.
