Introducing the BT-302 Polycarboxylate Superplasticizer - a marvel in concrete technology!
This high-performance superplasticizer boasts High Slump Retention with a Solid 50% concentration.
Product Introduction
Discover the BT-302, a groundbreaking generation of fast-releasing and dynamic slump retaining mother liquor, innovatively crafted from TPEG through advanced free radical polymerization, complemented by the introduction of a novel sustained-release group in its synthesis process. In the alkaline environment of concrete, the slow-releasing group in this product's molecular structure gradually releases a dispersive functional group, continuously dispersing the cement to effectively inhibit concrete slump loss. It boasts a minimal water reduction rate, yet excels in delivering superior slump protection performance.Typically paired with a water-reducing mother liquor, it is ideally utilized in high-strength concrete demanding exceptional slump protection. Its versatility extends to pumping concrete, super-flow self-compacting, and high-strength, high-performance concrete as well as commercial concrete for high-speed railways, expressways, hydro-power, and an array of large-scale engineering marvels.
Main Features
*The slow-release mother liquor outperforms faster-release PCE mother liquors.
Typically, the release occurs after 30 minutes (subject to material variations).
*Offers unmatched slump performance, maintaining concrete slump for 2 hours without loss.
*While it has a low water reduction rate, it is generally used in conjunction with a water-reducing mother liquor.
*Featuring low viscosity and thixotropy, it's ideal for concrete with a low water-cement ratio.

Application
1. Perfectly suited for the formulation of early strength concrete, retarded concrete, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concrete. Ideal for all industrial and civil building projects in premix cast-in-place concrete, particularly in low-grade commercial applications.
2. Widely applicable in high-speed railways, nuclear power sites, water conservancy and hydro-power endeavors, subways, grand bridges, expressways, harbors, and wharves, among other major and pivotal national projects.
3. Fits all types of industrial and civil construction and commercial concrete mixing stations.
How to Use
1. This product appears as a colorless or light yellow liquid. Dosage: Typically, use 0-30% mother liquor with a reducing water mother liquor, incorporating other minor materials to create a water-reducing agent. The dosage of this agent is generally 1% ~ 3% of the total cementing materials' weight.
2.Before introducing this product or altering the type and batch of cement and gravel, conducting adaptability tests with cement and gravel is crucial. Based on these tests, formulate the appropriate proportion of the water-reducing agent
3.This product can be used singly (although not typically advised to use it alone) This innovative solution can seamlessly blend with water-reducing mother liquor, offering a remarkable enhancement in concrete performance. It features sophisticated set retarding capabilities, and can be expertly combined with mother liquor to significantly diminish concrete slump loss. Alternatively, it can be compounded with advanced functional aids to craft admixtures with a multitude of benefits, including retarder, early strength, antifreeze, and superior pumping functions.The versatility of this product is unmatched. For optimal results, the application method and relevant conditions should be determined through comprehensive testing and advanced compounding technology.Always ensure the best performance.
4.This product offers exceptional compatibility with various admixtures such as early strength agents, air entrainment agents, and retarders. Ensure thorough testing before use, and avoid mixing it with naphthalene series water reducers to maintain concrete integrity.
5.The concrete cement and mix ratio should be meticulously determined by testing. During use, ensure the mixed and measured water is added concurrently with the concrete mixer. Conduct mixing tests beforehand to guarantee superior concrete quality.e
6.When integrating active admixtures like fly ash and slag in the concrete ratio, calculate the water-reducing agent based on the total amount of cementitious materials for optimized results.
