Introducing our cutting-edge BT-302 Polycarboxylate Superplasticizer, a marvel of modern construction technology.
Engineered to provide exceptional High Slump Retention with an impressive 50% Solid Content.
Product Introduction
BT-302 represents a new era in construction materials with its advanced, fast-releasing, and innovative formulation. Designed for superior slump retention. as a premium mother liquor, crafted from TPEG through state-of-the-art free radical polymerization, enhanced with an innovative sustained-release group to elevate synthesis.. When introduced to the alkaline environment of concrete, the slow-release groups within its molecular structure gradually unleash their dispersive capabilities, ensuring continuous cement dispersion. This effectively mitigates the issue of concrete slump loss,and it boasts a minimal water reduction rate, while offering unparalleled performance in slump protection..Typically paired with water reducing mother liquor, it is quintessential for high-strength concrete demanding superior slump protection. Its versatility shines in pumping concrete, super-flow self-compacting concrete, as well as high-performance commercial concrete tailored for high-speed railway, expressway, and hydro-power, along with other monumental engineering projects.
Main Features
*Our slow-release mother liquor is innovatively faster than traditional PCE mother liquor.
The release timeline typically commences after 30 minutes (modifiable depending on materials).
*Exhibits extraordinary slump performance, maintaining concrete slump for up to 2 hours without degradation.
*Designed with a low water reduction rate, it's generally combined with water reduction mother liquor for optimal results.
*Boasts low viscosity and thixotropy, particularly suitable for concrete with a reduced water-cement ratio.

Applications
1. Ideal for a variety of concrete types: early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concrete. Perfectly suited for industrial and civil constructions, particularly low-grade commercial concrete.
2. Extensively applicable in national infrastructure: high-speed railways, nuclear power, water conservancy, hydro-power projects, subways, large bridges, expressways, harbors, and wharves.
3. Tailored for diverse industrial and civil constructions, as well as commercial concrete mixing stations.
Usage Instructions
1. This innovative product is available as a colorless or light yellow liquid. Dosage: Typically,combine 0-30% of mother liquor with water-reducing mother liquor and integrate with other minor materials to formulate a water-reducing agent. The recommended dosage of the water-reducing agent ranges from 1% to 3% of the total cementitiousmaterials' weight. .
2.Prior to deployment or when altering the type or batch of cement and gravel, conduct adaptability tests to determine the optimal formulation of the water-reducing agent.
3.While this product can be used independently, it is generally recommended to use it in combination for enhanced effectiveness. Our innovative Eco-Friendly Slump Retention Polycarboxylate Superplasticizer Liquid, boasting a 50% solid formula, seamlessly combines with water-reducing mother liquor or set retarding agents, offering an effective solution to minimize concrete slump loss. Alternatively, it can be compounded with specialized additives, to create admixtures that deliver retarder, early strength, antifreeze, or pumping capabilities,tailored to meet diverse construction needs. For optimal results, application methods and conditions should be carefully assessed through testing and compounding technology,ensuring superior performance.
4.Our product is versatile and can be synergistically used with other admixtures like early strength agents, air entrainment agents, and retarders. It is crucial to conduct preliminary testing before use, and avoid mixing with naphthalene series water reducers to ensure compatibility.
5.Concrete cement and mix ratios should be established through rigorous testing. During application, ensure that the mixed and measured water is added simultaneously with our product into the concrete mixer. Prioritize conducting a mixing test to maintain the concrete's excellent quality.e
6.In scenarios where active admixtures such as fly ash and slag are used in the concrete mix, calculate the water-reducing agent based on the total cementing materials for optimal effectiveness.
