Presenting the BT-302 Polycarboxylate Superplasticizer
Experience Unmatched Performance with High Slump Retention Solid 50%
Product Introduction
BT-302 represents the pinnacle of modern superplasticizer technology, offering a cutting-edge formulation of fast-releasing and slump-retaining capabilities in a sophisticated mother liquor derived from TPEG, expertly crafted through free radical polymerization. This process introduces a novel sustained-release group enhancing the synthesis. When utilized under the alkaline conditions found in concrete, the innovative slow-releasing group within this product's molecular structure gradually liberates its dispersive functionalities, thereby maintaining cement dispersion and effectively inhibiting concrete slump loss. It boasts a modest water reduction rate, yet it excels in delivering exceptional slump protection performance.Although typically paired with a water-reducing mother liquor, it is predominantly tailored for high-strength concrete projects necessitating superior slump protection. Its applications span across pumping concrete, super-flow self-compacting, high-strength high-performance concrete, and commercial concrete for critical infrastructure such as high-speed railways, expressways, hydro-power, and other monumental engineering endeavors.
Main Features
*The innovative slow-release mother liquor is engineered to surpass the release speed of traditional PCE mother liquors.
The release timing generally commences after 30 minutes, subject to material-specific variations.
*Boasting extraordinary slump performance, this product ensures concrete slump retention for up to 2 hours without degradation.
*Due to its low water reduction rate, it is ordinarily not used in isolation. It requires integration with a water-reducing mother liquor.
*Characterized by low viscosity and thixotropy, it is optimally suited for concrete with reduced water-cement ratios.
