Introducing BT-302: The revolutionized Polycarboxylate superplasticizer that sets new benchmarks in construction chemistry.
Experience Unmatched Performance with High Slump Retention Solid at a robust 50% composition.
Product Introduction
BT-302 represents the apex of superplasticizer technology, designed as a fast-releasing marvel that elevates your concrete applications. Enhanced with superior slump retaining capabilities, crafted into a sophisticated mother liquor formulation using TPEG. This advanced product is synthesized through free radical polymerization, incorporating a groundbreaking sustained-release group. In the alkaline environment of concrete, this intelligent slow-releasing group gradually liberates dispersive agents, ensuring continuous dispersion of cement particles, effectively minimizing concrete slump loss.It offers an efficient yet reliably low water reduction rate, while delivering superior slump protection, safeguarding your concrete's fluidity over time.Typically paired with water reducing mother liquor, this product shines in high-strength concrete applications demanding exceptional slump retention. It's indispensable in pumping concrete, super-flow self-compacting, high-strength, high-performance concrete, and commercial concrete for projects like high-speed railways, expressways, and hydro-power plants, among other monumental engineering feats.
Main Feature
*The innovative slow-release mother liquor outpaces traditional PCE mother liquor with its rapid release action.
Typically activating after 30 minutes (subject to material-specific variations), it consistently delivers.
*Exhibiting extraordinary slump performance, it maintains concrete slump for an impressive 2 hours without degradation.
*While its low water reduction rate suggests combining with a water reduction mother liquor for optimal performance.
*Designed with low viscosity and thixotropy, it's ideally suited for concrete mixes with reduced water-cement ratios.

Application
1. Perfect for formulating early-strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concretes. Ideal for industrial and civil building projects where premix cast-in-place concrete is used, particularly low-grade commercial concrete.
2. Extensively applicable to high-speed railways, nuclear power, water conservation projects, subways, large-scale bridges, expressways, ports, wharves, and other significant national infrastructure.
3. Suitable for diverse industrial and civil construction projects and commercial concrete mixing stations.
How to Use
1. This product is available as a colorless or light yellow liquid, adaptable to diverse use cases. Dosage: Typically,utilize 0-30% of the mother liquor with a water-reducing mother liquor, blending in additional components to create an effective water-reducing agent. The advised dosage is usually 1% to 3% of the total cementitious materials weight.
2.Prior to application or when altering cement, gravel types, or batches, conduct compatibility tests. Adjust the water-reducing agent proportion per test results.
3.This product can be used solo (though usually not recommended), or integrated with water-reducing mother liquor for enhanced performance. set retarding Our premier mother liquor is designed to significantly reduce concrete slump loss, offering a seamless solution for construction challenges. Additionally, it can be ingeniously compounded with functional aids to create superior admixtures enhanced with retarder, early strength, antifreeze, and pumping functionalities. This revolutionary approach ensures versatility and efficiency in construction projects.. The application method and conditions should be determined by precise testing and advanced compounding technology..
4.This product is versatile and can be used in conjunction with other admixtures like early strength agents, air entrainment agents, retarders, etc. It is imperative to test before application to ensure compatibility. Note: Do not mix with naphthalene series water reducers.
5.Concrete The cement and mix ratio should be meticulously determined through testing. During use, both the mixed and measured water should be added simultaneously to the concrete mixer. Prior to application, a thorough mixing test is essential to maintain the concrete'sintegrity.
6.In cases where active admixtures such as fly ash and slag are part of the concrete mix, calculate the water-reducing agent amount based on the total volume of cementing materials for optimal results.
