BT-302 Polycarboxylate Superplasticizer
High Slump Retention Solid 50%
Product Introduction
BT-302 emerges as a cutting-edge solution, marking a new era of rapid-release and effective slump retention, crafted from a superior-quality TPEG base through advanced free radical polymerization. Enhanced with a novel sustained-release group, this synthesis elevates its capabilities.. In the alkaline environment of concrete, the slow-release component within this product's molecular framework gradually disperses, ensuring continuous cement dispersion for optimal retention.It features a modest water reduction ratio, yet excels in delivering unparalleled slump protection..Typically paired with water-reducing mother liquor, it excels in high-strength concrete applications demanding superior slump protection. Perfect for pumping concrete, ultra-flow self-compacting mixes, and top-end high-performance concrete, it serves commercial needs in high-speed railways, highways, and large-scale projects like hydro-power facilities and other monumental engineering endeavors.
Main Features
*Boasts faster release capabilities compared to standard PCE mother liquors.
The release typically commences around 30 minutes post-application, though timing may vary with material compositions.
*Delivers exceptional slump retention, ensuring 2-hour slump stability without degradation.
*While it has a lower water reduction capability, it's generally used in conjunction with water-reducing mother liquors.
*Low viscosity and thixotropic properties make it ideal for concrete with reduced water-cement ratios.

Applications
1. Ideal for formulating early-strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concrete types. Perfect for premix applications in both industrial and civil construction, particularly beneficial for low-grade commercial concrete.
2. Highly recommended for use in high-speed rail, nuclear power, water conservancy, hydro-power projects, subways, large bridges, expressways, harbors, and other significant national projects.
3. Suitable for all industrial, civil construction, and commercial concrete mixing stations.
How to Use
1. This product features a colorless or delicate light yellow hue. Dosage: Typically,blend 0-30% of the mother liquor with the water-reducing mother liquor, incorporating other minor additives to create an effective water-reducing agent. The typical dosage ranges from 1% to 3% of the total cementing materials' weight.
2.Prior to application or when switching cement and aggregate types or batches, conduct compatibility tests to determine the ideal water-reducing agent formulation.
3.This product can be used independently (though typically not recommended solo) It is best used in conjunction with water-reducing mother liquors, enhancing its effectiveness. Set Retarding: Discover the remarkable ability of our product to expertly delay the setting process, ensuring optimal workability and superior performance. Harness the power of our cutting-edge mother liquor to effectively reduce concrete slump loss, while seamlessly integrating with functional aids. Unlock the potential of your concrete mixtures by compounding with our premium additives to achieve tailored solutions with retarder, early strength, antifreeze, and pumping functions.. For precise application, the methodology and conditions should be ascertained through meticulous testing and sophisticated compounding technology..
4.This outstanding product can be synergistically used with a variety of admixtures such as early strength agents, air entrainment agents, and retarders, ensuring enhanced results. It is crucial to conduct thorough tests prior to use. Please refrain from mixing with naphthalene series water reducers to maintain efficacy.
5.Concrete cement and mix ratio should be meticulously determined through comprehensive testing. During use, ensure that the mixed and measured water is added accurately at the same time as it enters the concrete mixer. A preliminary mixing test is essential to guarantee the flawless quality of the concretee.
6.For concrete compositions containing active admixtures like fly ash and slag, calculate the water-reducing agent based on the total cementitious materials to achieve optimal results.
