BT-302 Polycarboxylate Superplasticizer
Marvelous High Slump Retention in Solid Form, 50% Concentration
Product Introduction
Introducing BT-302, a groundbreaking, next-generation superplasticizer engineered for rapid release and unparalleled slump retention. Maximizing consistency with its innovative TPEG base, crafted through advanced free radical polymerization. A novel sustained-release group is intricately woven into its synthesis,ensuring superior performance. In the alkaline environment of concrete, BT-302's slow-releasing molecular group gradually unveils a dispersive function, persistently dispersing cement particles.This profoundly inhibits concrete slump loss, despite its low water reduction rate, while offering exceptional slump protection.It isbest deployed alongside water-reducing mother liquor. Primarily designed for high-strength concrete demanding supreme slump retention, BT-302 has become indispensable in applications such as pumping concrete, super-flow self-compacting, and high-strength, high-performance concretes. Perfect for commercial concrete in high-speed railways, expressways, hydro-power, and other monumental engineering feats.Ideal for massive-scale projects.
Main Features
* Boasting slow-release mother liquor with faster PCE mother liquor release.
Typically, the release commences post 30 minutes (depending on specific material variations).
* Features extraordinary slump retention, maintaining concrete slump for 2 hours without any loss.
* Due to its low water reduction rate, it is generally used in conjunction with water-reducing mother liquor.
* With low viscosity and thixotropy, it is particularly suited for concrete with a low water-cement ratio.

Application
1. Perfectly tailored for early-strength concrete, retarded concrete, precast and cast-in-place concrete, flow concrete, self-compacting concrete, mass concrete, high-performance and clear concrete. Ideally suited for all kinds of industrial and civil structures, particularly low-grade commercial concrete.
2. Embraced by sectors such as high-speed railways, nuclear power, water conservancy, subways, large bridges, expressways, harbors, wharves, and other significant national projects.
3. Unmatched versatility in various industrial, civil construction, and commercial concrete mixing stations.
How to Use
1. Presented as a colorless or light yellow liquid. Dosage: Typically,combine 0-30% mother liquor with water-reducing mother liquor, incorporating additional materials to create a water-reducing agent. The agent's standard dosage ranges from 1% to 3% of the total weight of the cementingmaterials. 2.
Before employing this product or transitioning between cement and gravel types and batches, an adaptability test is crucial. Use test results to determine the precise proportion of water-reducing agent.3.
Although this product can beused solo (with exceptions), it harmonizes best when combined with water-reducing mother liquor. This ensures optimal performance and efficiency. Achieve exceptional control with our set retarding technology. Introducing our mother liquor, expertly designed to minimize concrete slump loss. Combine seamlessly with functional aids to craft tailor-made admixtures featuring retarder, early strength, antifreeze, and enhanced pumping capabilities. To ensure optimal performance, determine the application method and conditions through rigorous testing and advanced compounding technology.
4.This innovative product is versatile, working harmoniously with other admixtures like early strength agents, air entrainment agents, and retarders. However, always conduct preliminary tests before use. Note: Avoid mixing with naphthalene series water reducers.
5.For Concrete ensure the cement type and mix ratio are determined through thorough testing. During application, incorporate the mixed and measured water simultaneously into the concrete mixer. Prior to use, perform a mixing test to guarantee superior concrete quality.
6.When utilizing active admixtures such as fly ash and slag within the concrete ratio, calculate the water-reducing agent based on the total cementing materials to ensure consistency.
