BT-302 Polycarboxylate Superplasticizer: A Revolution in Concrete Enhancement
High Slump Retention with 50% Solid Concentration: Elevate Your Construction Standards!
Product Introduction
Experience the next-generation innovation with our BT-302, a revolutionary fast-releasing and exceptionally effective slump-retaining solution crafted from meticulously processed TPEG through state-of-the-art free radical polymerization. A groundbreaking sustained-release group has been seamlessly integrated into its synthesis. In the alkaline environment of concrete, the slow-releasing group within this product's molecular structure gradually releases a dispersive function group, continuously dispersing cement. This effectively curtails concrete slump loss. It boasts a remarkably low water reduction rate , yet offers superior slump protection capabilities.Designed to complement water-reducing mother liquor, this product excels in high-strength concrete applications demanding exceptional slump protection. It finds extensive use in pumping concrete, super-flow self-compacting concrete, high-performance construction, and commercial concrete for pivotal infrastructure projects like high-speed railways, expressways, and hydro-power ventures.
Main Features
* The slow-release mother liquor surpasses traditional PCE mother liquor in release speed.
The release typically occurs post 30 minutes, though this can vary with different materials.
* With outstanding slump performance, this product maintains concrete slump for 2 hours without degradation.
* Its low water reduction rate necessitates combination with a water-reducing mother liquor for optimal results.
* Boasting low viscosity and thixotropy, it is ideally suited for concrete formulations with a low water-cement ratio.

Application
1. Perfect for early strength concrete, retarded concrete, precast and cast-in-place concrete, flow concrete, self-compacting concrete, mass concrete, high-performance concrete, and clear concrete. It is especially beneficial for low-grade commercial concrete in industrial and civil buildings.
2. Exceptionally versatile, it is applicable to high-speed railways, nuclear power projects, water conservancy and hydro-power projects, subways, grand bridges, expressways, harbors, wharves, and other significant national projects.
3. Suitable for a wide range of industrial and civil construction projects, as well as commercial concrete mixing stations.
How to Use
1. This product is a colorless or light yellow liquid. Dosage: Typically,use 0-30% of the mother liquor in combination with a reducing water mother liquor, supplemented by other minor materials to formulate a water-reducing agent. The general usage is 1% to 3% of the total weight of cementitiousmaterials.
2.Before using this product, or when altering cement and gravel types or batches, conduct an adaptability test with both. Utilize results to refine the water-reducing agent's composition.
3.This product can be used singularly (though typically not recommended alone). It can be effectively combined with water-reducing mother liquor for enhanced performance. Experience the remarkable capabilities of set retarding, achieving optimal performance in diverse applications. Harness the power of mother liquor to significantly reduce concrete slump loss, or combine with versatile functional aids, thereby creating admixtures that feature enhanced retarder, early strength, antifreeze, and pumping functions.. For the best results, determine the application method and conditions through comprehensive testing and state-of-the-art compounding technology..
4.Compatibility is key! This product seamlessly integrates with other admixtures such as early strength agents, air entrainment agents, and retarders. However, it is crucial to conduct tests before use. Avoid mixing with naphthalene series water reducer to ensure optimal performance.
5.Concrete Mix and measure with precision! The cement and mix ratio should be determined by testing. When using, ensure that both mixed and measured water are added simultaneously to the concrete mixer. Conduct a mixing test beforehand to guarantee the superior quality of the concrete.e
6.Maximize effectiveness by calculating the amount of water-reducing agent as the total amount of cementing materials when active admixtures like fly ash and slag are present in the concrete ratio.
