Introducing the advanced BT-302 Polycarboxylate Superplasticizer, designed to elevate your construction projects with unmatched effectiveness.
Experience unparalleled performance with our High Slump Retention Solid at an impressive 50% concentration, ensuring consistent and reliable results.
Product Introduction
BT-302 represents a cutting-edge innovation in the realm of fast-releasing and slump-retaining capabilities, featuring a mother liquor crafted from TPEG utilizing free radical polymerization. Enhanced with a specially devised sustained-release group, this synthesis processensures longevity and reliability. In concrete's alkaline environment, the product's unique slow-releasing group gradually unleashes its dispersive function, continuously dispersing cement particles to effectively prevent slump loss,ensuring your mix maintains a robust, although low water reduction rate, with exceptional slump protection.It iscommonly paired with water-reducing mother liquor. This product is tailored for high-strength concrete requiring superior slump protection, and is ideally suited for pumping concrete, super-flow self-compacting formulations, as well as high-strength, high-performance concrete. It is also integral to commercial concrete applications in high-speed railway, expressway, hydro-power, and other monumental engineering infrastructures.
Main Features
*The slow-release mother liquor is engineered to act faster than traditional PCE mother liquors.
Release occurs typically around 30 minutes, adjustable based on material properties.
*Exhibits extraordinary slump performance, maintaining concrete slump for up to 2 hours without loss.
*While having a low water reduction rate, it is generally used in combination with a water-reducing mother liquor for optimal results.
*Boasting low viscosity and thixotropy, it is ideally suited for concrete mixes with a low water-cement ratio.

Applications
1. Perfect for formulating early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concrete. Suitable for both industrial and civil premix cast-in-place projects, particularly low-grade commercial concrete.
2. Highly adaptable for use in high-speed railways, nuclear power, water conservancy, hydro-power, subway, large bridges, expressways, harbors, and wharves, serving national large-scale projects.
3. Applicable for a variety of industrial and civil construction projects, as well as commercial concrete mixing stations.
How to Use
1. This product is available as a colorless or light yellow liquid. Dosage: Typically, use 0-30% mother liquor with a water-reducing mother liquor, blending with other small materials to create an effective water-reducing agent. Recommended dosage of the water-reducing agent is generally 1% ~ 3% of the total cementing material weight.
2.Before employing this product or altering the type and batch of cement and gravel, perform an adaptability test to ensure compatibility and adjust the composition of the water-reducing agent accordingly.
3.While this product can be used alone (though it's not common), it generally delivers better performance when combined with other components. This dynamic product can seamlessly blend with water-reducing mother liquor, enhancing its versatility. It can also incorporate set retarding agents, allowing it to effectively minimize concrete slump loss or be combined with specialized aids to formulate admixtures that boast properties such as retardation, early strength development, antifreeze capabilities, and improved pumping functions.This adaptability makes it a cornerstone in innovative concrete solutions. For optimal performance, application methods and conditions need careful assessment through testing and expert compounding technology,ensuring the highest quality results.
4.This product exhibits exceptional compatibility with a variety of admixtures, including early strength agents, air entrainment agents, retarders, and more. However, it is crucial to conduct thorough testing before use and strictly avoid mixing it with naphthalene series water reducers.
5.To achieve superior concrete performance, it's essential to determine the concrete cement and mix ratio through rigorous testing. During application, ensure that the mixed and measured water is added simultaneously with the product to the concrete mixer. Always perform a comprehensive mixing test beforehand to guarantee the concrete's quality and integrity.
6.In scenarios where active admixtures like fly ash and slag are included in the concrete mix, calculate the water-reducing agent's dosage as part of the total cementing materials to maintain optimal performance.
