BT-302 Polycarboxylate Superplasticizer: Revolutionizing Concrete Performance
High Slump Retention, Solid 50% Formula: Excellence in Every Pour
Product Introduction: Elevating Concrete Standards with BT-302
BT-302 heralds a new era of innovative concrete solutions with its fast-releasing features and exceptional slump retention, crafted meticulously from a unique TPEG formulation via advanced free radical polymerization, enhanced by a novel sustained-release synthesis. In concrete's alkaline environment, the slow-releasing molecular structure of this product artfully dispenses dispersion agents, masterfully managing cement spread and seamlessly inhibiting slump loss. Its water-reduction rate is low, but its slump protection is extraordinarily high, ensuring superior performance in demanding construction scenarios.Optimally paired with water-reducing agents, it excels in high-strength concrete needing robust slump protection, ideal for pumping, super-flow, self-compacting, high-performance concrete, and commercial concrete for ambitious infrastructure projects like high-speed railways, expressways, and hydroelectric powerinstallations.
Main Features: Unveiling the Excellence of BT-302
*The innovative slow-release mother liquor outpaces conventional PCE mother liquor, transforming concrete practices.
The release initiates generally around 30 minutes, adaptable to material conditions
*Remarkably high slump performance ensures no slump loss for up to 2 hours
*Designed for synergy, its low water reduction rate requires pairing with water-reducing agents for optimal results
*Low viscosity and thixotropy make it ideal for concrete with a low water-cement ratio

Applications: Versatility Across Construction Landscapes
1. Ideal for early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concrete, BT-302 adapts seamlessly to industrial and civil premix applications, particularly excelling in low-grade commercial concrete.
2. Its adaptability extends to high-profile projects including high-speed rail, nuclear energy, water conservancy, subways, grand bridges, expressways, harbors, and wharves.
3. Perfectly suited to diverse industrial, civil, and commercial concrete mixing stations.
How to Use: Guiding You to Maximum Efficiency
1. Presented as a colorless or light yellow liquid, it speaks of purity and precision. Dosage: Employ 0-30% mother liquor synergized with water-reducing agents, blending additional materials to craft an efficient water-reducing solution. Apply at 1% - 3% of total cementitious weight for optimal results.
2. Conduct compatibility tests with cement and gravel prior to usage, especially when changing cement or gravel types to tailor the water-reducing agent accordingly.
3. While it can be used alone (typically not advised), its power is best unleashed when combined strategically. Unlock the full potential of Versatile Polycarboxylate Superplasticizer Liquid by combining it with water-reducing mother liquor. This synergy creates a powerful blend that elevates performance. This remarkable solution is designed for set retarding, and the innovative mother liquor effectively minimizes concrete slump loss, ensuring consistency and durability. Explore the benefits of compounding with functional aids, crafting admixtures that offer retarder, early strength, antifreeze, and pumping functionalities to meet diverse construction needs.. Ensure your success by tailoring application methods and conditions through rigorous testing and advanced compounding technology..
4.Enhance compatibility and performance by using this product alongside other admixtures such as early strength agents, air entrainment agents, and retarders. Always conduct a pre-use test. Important: Avoid mixing with naphthalene series water reducers to prevent incompatibility.
5.Achieve optimal concrete performance: carefully determine the concrete cement and mix ratio through comprehensive testing. When ready, incorporate the mixture with precision by adding the mixed and measured water to the concrete mixer simultaneously. Conduct a thorough mixing test beforehand to guarantee superior concretequality.
6.For concrete blends containing active admixtures like fly ash and slag, accurately calculate the water-reducing agent dosage based on the total cementing materials to maintain optimal performance.
