Introducing BT-302: A premier Polycarboxylate Superplasticizer
Renowned for its High Slump Retention and Solid 50% Formula
Product Introduction
BT-302 represents a groundbreaking advancement in fast-releasing technology and exceptional slump retention capabilities. This innovative mother liquor is crafted from TPEG via advanced free radical polymerization. A novel sustained-release group is meticulously integrated into the synthesisprocess. In the alkaline environment of concrete, the slow-releasing group within this product's molecular structure gradually delivers its dispersive properties. This continual dispersion of cement significantly inhibits concrete slump loss,ensuring longevity. Boasts a modest water reduction rate, while excelling in high-performance slump protection.Perfect choice for challenging conditions.Best used alongside water-reducing mother liquor, it predominantly serves high-strength concrete with stringent slump protection needs. Ideal for pumping concrete, super-flow self-compacting concrete, and robust high-performance concrete. Widely adopted in commercial concrete applications for high-speed railways, expressways, hydro-power projects, and other extensive engineering undertakings.
Main Features
*Pioneering slow-release mother liquor surpasses traditional PCE variants in release speed.
With typical release commencing after 30 minutes (varying with material specifics).
*Showcases extraordinary slump performance, maintaining concrete slump for over 2 hours.
*Low water reduction rate mandates its use in conjunction with water-reducing mother liquor for optimal results.
*Characterized by low viscosity and thixotropy, it's tailored for concrete necessitating a low water-cement ratio.

Applications
1. Seamlessly fits the formulation of early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concrete. Supports all industrial and civil structures through premix cast-in-place concrete, making it especially suitable for low-grade commercial applications.
2. Extensively applicable to high-speed railways, nuclear power facilities, water conservation, hydro-power initiatives, subways, monumental bridges, expressways, harbors, wharves, and other national-scale and key infrastructure projects.
3. Ideal for diverse industrial and civil construction endeavors and commercial concrete mixing stations.
How to Use
1. The product appears as a colorless or subtly light yellow liquid. Dosage: Typically,incorporate 0-30% mother liquor with the water-reducing counterpart, blending with auxiliary materials to create a water-reducing agent. The recommended dosage of this agent spans 1% ~ 3% of the comprehensive cementions composition.
2.Conduct adaptability tests with cement and gravel before deploying this product or altering cement and gravel types and batches. Formulate the water-reducing agent proportion based on test outcomes.
3.While this product can be used independently (though not typically recommended) it can be effectively combined with water-reducing mother liquor for enhanced performance. Discover the benefits of set retarding, a key feature that empowers your concrete projects to maintain optimal workability over time. Dive into the advantages of our mother liquor, expertly formulated to significantly reduce concrete slump loss. Ideal for seamless integration or compounding with functional aids to create a multifaceted admixture. Enhance your concrete with retarder, early strength, antifreeze, and pumping functionalities.. Ensure maximum efficiency and effectiveness by carefully determining application methods and conditions through rigorous testing and advanced compounding technology..
4.Maximize performance by using this product in conjunction with other admixtures like early strength agents, air entrainment agents, and retarders. Conduct thorough testing before use to ensure compatibility. Please refrain from mixing with naphthalene series water reducers.
5.Optimize your concrete's cement and mix ratio through comprehensive testing. When in use, incorporate mixed and measured water simultaneously with the concrete mixer. Prior to application, perform a mixing test to guarantee the highest quality.e
6.For concrete mixes containing active admixtures such as fly ash and slag, calculate the water-reducing agent based on the total cementing materials to achieve optimal results.
