BT-302 Polycarboxylate Superplasticizer: Elevate your concrete mixtures with this state-of-the-art solution.
High Slump Retention Solid 50%: Ensuring robust workability in concrete mixtures.
Product Introduction: Discover the pioneering advantages of BT-302.
BT-302 is a revolutionary new-generation superplasticizer, engineered for exceptional slump retention, crafted from superior-grade TPEG via advanced free radical polymerization techniques, incorporating a novel sustained-release group into the formula. In the alkaline environment of concrete, this product's unique slow-releasing molecular group gradually disperses, providing ongoing cement dispersion and effectively mitigating concrete slump loss. It boasts a moderate water reduction rate, yet delivers exceptional slump protection performance.Typically utilized in conjunction with a water-reducing mother liquor, it is primarily intended for use in high-strength concrete demanding superior slump protection, and its applications span pumping concrete, super-flow self-compacting and high-strength high-performance concrete as well as commercial concrete tailored for high-speed railways, expressways, and hydro-power infrastructures and other major engineering projects.
Main Feature: Unleash the full potential of your concrete projects.
*Faster release than conventional PCE mother liquor, thanks to the innovative slow-release formulation.
With a typical release time initiated 30 minutes post-application (dependent on material characteristics).
*Achieve unsurpassed slump retention, maintaining slump for up to 2 hours.
*This product's low water reduction rate necessitates its combination with a water-reducing mother liquor for optimal performance.
*Featuring low viscosity and enhanced thixotropy, it is ideally suited for concrete formulations with low water-cement ratios.

Application: Versatile solutions for diverse construction needs.
1. Suitable for configuring early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concrete, catering to all types of industrial and civil structures, especially for lower-grade commercial concrete.
2. Extensively applicable in high-speed railways, nuclear power, water conservancy projects, subways, large bridges, expressways, harbors, and wharves as part of national large-scale and key construction projects.
3. An essential component for industrial and civil construction sites and commercial concrete mixing stations.
How to Use: Ensure peak performance and reliability.
1. This product is available as a colorless or light yellow liquid. Dosage: Typically, use 0-30% mother liquor combined with the reducing water mother liquor, integrating additional minor materials to craft a water-reducing agent. The recommended dosage of this agent is generally 1% ~ 3% of the total weight of cementing materials.
2.Prior to utilization, or when altering the type and batch of cement and aggregate, it is essential to conduct an adaptability test with cement and gravel to determine the optimal water-reducing agent proportion based on test outcomes.
3.While this product can be used independently (although not typically advised), it can also be optimally combined with a water-reducing mother liquor for enhanced results. Set Retarding: Master the art of controlling your concrete setting times with our highly effective set retarding capabilities. Our mother liquor is expertly formulated to significantly reduce concrete slump loss, ensuring a consistent quality in every pour. Ideal for compounding with robust functional aids, providing a versatile mix that exceeds expectations. Create tailor-made admixtures that introduce retarder, early strength, antifreeze, and efficient pumping functionalities, elevating your concrete to new heights.. To achieve optimal results, determine the application method and conditions through comprehensive testing and advanced compounding technology..
4.Our product harmonizes effortlessly with a variety of admixtures such as early strength agents, air-entraining agents, retarders, and more. Conduct thorough testing before use. Note: Avoid mixing with naphthalene series water reducers for best results.
5.Concrete mix perfection starts with precise testing. Cement and mix ratios need careful determination. Ensure mixed and measured water is added simultaneously with the admixture to the mixer. Conduct preliminary mixing tests to guarantee impeccable concrete quality. concretee
6.Maximize efficiency when using active admixtures like fly ash and slag. Calculate the water-reducing agent as part of the total cementitious materials for supreme performance.
