BT-302 Polycarboxylate Superplasticizer for High Slump Retention Concrete
Product Introduction:
Our BT-302 represents a new era of fast-releasing, slump-retaining technology, ensuring that your concrete maintains its desired properties over extended periods. This innovative mother liquor is meticulously crafted from TPEG using a state-of-the-art free radical polymerization process. We've introduced a groundbreaking sustained-release group into the synthesis,offering unparalleled performance. In alkaline concrete conditions, the product's slow-releasing molecular structure gradually discharges dispersion groups, effectively dispersing cement and reducing slump loss.It boasts a low water reduction rate, while delivering exceptional slump protection, perfect for demanding projects..Commonly paired with water-reducing mother liquor, BT-302 excels in high-strength concrete applications with stringent slump protection needs. Its versatility spans pumping concrete, self-compacting and high-performance applications, including projects for high-speed railways, expressways, and hydropower.Ideal for major engineering feats.
Main Features: Discover the unmatched benefits.
*Innovative slow-release mother liquor, surpassing traditional PCE mother liquors.
The release is optimally timed, generally around 30 minutes, varying with specific materials.
*Boasting superior slump maintenance, concrete retains its slump for up to 2 hours without loss.
*Typically not used alone due to low water reduction rate; combines effectively with other mother liquors.
*Low viscosity and thixotropy make it ideal for low water-cement ratio concrete applications.
Typical Characteristics: Elevating concrete's physical properties.

Application: Versatility across sectors.
1. Ideal for early strength, retarded, precast, cast-in-place, flow, self-compacting, and high-performance concrete, catering to both industrial and civil projects, particularly low-grade commercial concrete.
2. Extensively applicable in high-speed railways, nuclear power, water conservancy, subways, large bridges, expressways, harbors, and other significant national projects.
3. Perfect for diverse industrial, civil construction, and commercial concrete mixing stations.
How to Use: Maximizing efficiency and performance.
1. This product is offered as a colorless or light yellow liquid. Dosage: Generally,combine 0-30% of this mother liquor with water-reducing mother liquor, mixing with additional materials to create a water-reducing agent. Typically, the dosage for the agent is around 1% ~ 3% of the total weight of cementing materials.
2.Conduct adaptability tests with cement and gravel before use or when altering cement and gravel types or batches to formulate the perfect water-reducing agent proportion based on the results.
3.This product can be used alone, though typically combined for optimal results. Elevate your concrete projects with our Advanced Polycarboxylate Superplasticizer, designed to be seamlessly combined with water-reducing mother liquor for optimal results and enhanced performance. Experience superior control over concrete set times with the addition of set retarding mother liquor, effectively combating concrete slump loss for more durable structures. Alternatively, pair with functional aids to craft specialized admixtures that deliver retarder, early strength, antifreeze, and enhanced pumping capabilities, tailored to your project's unique demands.. To achieve the best application results, the method and conditions should be meticulously determined by rigorous testing and advanced compounding technology..
4.Our product harmoniously complements other admixtures such as early strength agents, air entrainment agents, and retarders. It's essential to conduct compatibility tests prior to use. Note: Avoid mixing with naphthalene series water reducers to maintain product integrity.
5.For impeccable concrete formulation, cement and mix ratios must be precisely determined through testing. During usage, synchronize the addition of mixed and measured water with the concrete mixer. Prior mixing tests are crucial to ensure the superior quality and performance of the concrete.
6.In scenarios where active admixtures like fly ash and slag are present, calculate the water-reducing agent based on the total quantity of cementitious materials for consistent results.
