BT-302 Polycarboxylate Superplasticizer: Elevate your concrete mix with this cutting-edge superplasticizer designed for unparalleled performance.
Experience Remarkable High Slump Retention with Solid 50% Formula.
Product Introduction: Discover the future of concrete admixtures with our advanced formula.
BT-302 represents a new generation of fast-releasing technology and remarkable slump retaining capabilities. This innovative mother liquor is crafted from TPEG through free radical polymerization, incorporating a novel sustained-release group in its synthesis.. In alkaline concrete conditions, the slow-releasing group within this product's molecular structure gradually releases dispersive agents, continuously dispersing cement to effectively prevent slump loss.It boasts a modest water reduction rate, while delivering exceptional slump protection properties..Typically paired with water-reducing mother liquor, this product is ideal for high-strength concrete demanding superior slump retention. Its use spans pumping concrete, super-flow self-compacting, high-strength high-performance, and commercial concrete applications, including high-speed railways, expressways, and hydro-power projects, and other substantial engineering ventures.
Main Features: Unleash the potential of your concrete mixes.
*The innovative slow-release mother liquor transforms faster than conventional PCE variants.
Typically activating post 30 minutes (varies based on material specifics).
*Exhibits extraordinary high slump retention, maintaining concrete slump for 2 hours without loss.
*Though it has a lower water reduction rate, it excels when combined with water-reducing mother liquor.
*Boasting low viscosity and thixotropy, it's optimally suited for concrete with lower water-cement ratios.
Typical Characteristics: A testament to innovation in concrete technology.

Application: Versatility across numerous construction domains.
1. Perfect for early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and clear concrete in industrial and civil buildings, premix, and low-grade commercial concrete.
2. Ideal for national large and key projects, including high-speed railways, nuclear power, water conservancy, hydro-power, subways, large bridges, expressways, harbors, and wharves.
3. Suitable for all industrial, civil construction, and commercial concrete mixing stations.
How to Use: Master the art of application.
1. This product is available in a colorless or light yellow liquid form. Dosage: Typically, use0-30% of the mother liquor with a water-reducing mother liquor, mixing with other minor materials to craft the water-reducing agent. Generally, the agent's dosage is around 1% ~ 3% of the total cementitious material weight. materials.
2.Before utilizing this product or altering the type and batch of cement and gravel, it is imperative to perform an adaptability test. Based on test results, determine the appropriate water-reducing agent proportions.
3.This product can be used singularly (though typically not recommended). This innovative product can be seamlessly integrated with water-reducing mother liquor, set retarding properties, to effectively curb concrete slump loss. Alternatively, it can be expertly compounded with other functional aids, to craft admixtures boasting retarder, early strength, antifreeze, and pumping functionalities. The precise application method and conditions should be ascertained through rigorous testing and advanced compounding technology.
4.This versatile product can be synergistically used with a variety of admixtures including early strength agents, air entrainment agents, retarders, etc. It is imperative to conduct thorough tests before use. Do not use with naphthalene series water reducers.
5.The concrete cement composition and mix ratio should be meticulously determined by testing. During mixing, the combined and measured water must be added simultaneously to the concrete mixer. Conduct comprehensive mixing tests beforehand to ensure superior concrete quality.
6.In scenarios involving active admixtures such as fly ash and slag, calculate the water-reducing agent's quantity based on the total amount of cementing materials to achieve optimal results.
