Introducing the BT-302 Polycarboxylate Superplasticizer, a cutting-edge marvel in construction additives.
Experience unmatched performance with our High Slump Retention Solid at an impressive 50% concentration.
Product Introduction
BT-302 represents a new era in fast-releasing, slump-retaining technology, ensuring optimal consistency and durability. Crafted from mother liquor utilizing TPEG, this product is synthesized through advanced free radical polymerization, incorporating a revolutionary sustained-release group. In the alkaline environment of concrete, this molecular marvel releases its dispersive agents gradually, maintaining extended cement dispersion and effectively preventing slump loss. It boasts a modest water reduction rate, yet offers exceptional slump protection. Ideal for pairing with water-reducing mother liquor, BT-302 excels in high-strength concrete applications demanding superior slump protection. Its extensive use spans pumping concrete, ultra-flow self-compacting, high-strength, high-performance concrete, and commercial concrete for critical infrastructures like high-speed railways, expressways, and hydroelectric projects and monumental engineering ventures.
Main Features
*This innovative slow-release mother liquor outpaces traditional PCE mother liquors.
Typically releasing after 30 minutes (variable based on material specifics),
*Exhibits extraordinary slump performance, allowing concrete to maintain slump for up to 2 hours without loss.
*Due to its low water reduction rate, it is usually combined with water-reducing mother liquor for best results.
*Characterized by low viscosity and thixotropy, making it ideal for concrete with low water-cement ratios.

Applications
1. Perfect for configuring early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concrete, suitable for industrial and civil buildings in premix and cast-in-place concrete, particularly low-grade commercial concrete.
2. Extensively applicable in major infrastructure projects such as high-speed railways, nuclear power plants, water conservancy, hydro-power, subways, grand bridges, expressways, harbors, and wharves.
3. Tailored for all industrial and civil construction, as well as commercial concrete mixing stations.
How to Use
1. The product is available as a colorless or light yellow liquid. Dosage: Typically,utilize 0-30% mother liquor in combination with water-reducing mother liquor, and incorporate other minor materials to craft a potent water-reducing agent. The standard dosage of the agent is 1% ~ 3% of the total weight of cementing materials.
2. It is crucial to conduct adaptability tests with cement and gravel before first use or when changing cement and gravel types or batches. These tests inform the formulation of water-reducing agent proportions.
3. While this versatile product can be used independently (though typically not recommended), it is highly effective when combined with water-reducing mother liquor for enhanced results. Set retarding: A sophisticated approach to managing your concrete's setting time, providing ample working time and enhancing the overall quality of your mixture. Mother liquor to effectively curb concrete slump loss or blend with specialized functional aids. Aids: Enhance your concrete mix with tailored solutions that cater to specific needs. To achieve admixtures with multifaceted capabilities, such as retarder, early strength, antifreeze, and pumping functions.. The application methods and conditions should be precisely determined by comprehensive testing and advanced compounding technology..
4.This product synergizes with multiple admixtures like early strength agents, air entrainment agents, and retarders. Conduct thorough testing prior to usage. Ensure not to mix with naphthalene series water reducer for optimal performance.
5.Concrete: Cement and mix ratios must be ascertained through rigorous testing. When applying, add the mixed and measured water simultaneously with the concrete into the mixer. Conduct pre-application mixing tests to guarantee superior concrete quality.e
6.Incorporate active admixtures such as fly ash and slag? Calculate the water-reducing agent based on the total cementitious materials for precision.
