Discover the Excellence of BT-302 Polycarboxylate Superplasticizer
Harness the Power of High Slump Retention with Solid 50%
Product Overview
BT-302 is a state-of-the-art, fast-releasing innovation that prioritizes slump retention. This superior mother liquor, crafted from TPEG, utilizes advanced free radical polymerization, incorporating a groundbreaking sustained-release group within its synthesis. In the alkaline environment of concrete, the meticulously designed slow-releasing group within this product's molecular structure gradually releases a dispersive function, enhancing cement dispersion and effectively mitigating concrete slump loss, ensuring lasting performance.. It features a modest water reduction rate, yet delivers exceptional slump protection characteristics.Typically used in conjunction with water reducing mother liquor, it excels in high-strength concrete applications demanding superior slump protection, making it an ideal choice for pumping concrete, ultra-fluid self-compacting concrete, high-strength performance concrete, and commercial concrete used in high-speed railway, expressway, and hydro-power and other expansive engineering endeavors.
Key Features
*The slow-release mother liquor offers quicker release compared to PCE mother liquor.
Release typically occurs after 30 minutes, subject to material influences.
*Exhibits ultra-high slump performance, maintaining concrete slump for up to 2 hours without any loss.
*Low water reduction rate suggests combination use with water reduction mother liquor for optimal results.
*Boasts low viscosity and thixotropy, perfect for concrete with a low water-cement ratio.

Applications
1. Ideally suited for early strength concrete, retarded concrete, precast concrete, cast-in-place concrete, flow concrete, self-compacting concrete, mass concrete, high-performance concrete, and clear concrete across diverse industrial and civil buildings, especially tailored for low-grade commercial concrete applications.
2. Perfectly applicable to national large-scale and key projects like high-speed railways, nuclear power, water conservation and hydro-power projects, subways, large bridges, expressways, harbors, and wharves.
3. Versatile for all industrial, civil construction, and commercial concrete mixing stations.
Usage Instructions
1. This product is presented as a colorless or light yellow liquid. Dosage Recommendations: Typically,use 0-30% mother liquor combined with reducing water mother liquor, complemented by additional minor materials to formulate the water reducing agent. Usage of water-reducing agent usually falls between 1% to 3% of the total cementing materials weight.
2.Prior to usage or when altering the type and batch of cement and gravel, perform an adaptability test with cement and gravel. Formulate the water reducing agent proportion based on test outcomes.
3.This product can be used singly (although generally not preferred), or it can be seamlessly combined with water-reducing mother liquor for enhanced performance. Experience the superior benefits of set retarding properties. Our innovative mother liquor significantly reduces concrete slump loss, ensuring a consistent and reliable mix. It can be expertly compounded with functional aids to craft premium admixtures, offering enhanced retarder, early strength, antifreeze, and efficient pumping functionalities.. The ideal application method and conditions are best determined through meticulous testing and advanced compounding technology..
4.Our product harmoniously integrates with other admixtures, such as early strength agents, air-entraining agents, and retarders. For optimal performance, always conduct tests before use. Note: Avoid mixing with naphthalene series water reducers.
5.Concrete cement and mix ratios should be meticulously determined by comprehensive testing. During application, ensure that mixed and measured water is added to the concrete mixer simultaneously. Conduct a thorough mixing test beforehand to guarantee exceptional concrete quality.e
6.When utilizing active admixtures such as fly ash and slag within the concrete ratio, calculate the water-reducing agent based on the total amount of cementing materials for optimal results.
