Product Description

BT-302 Polycarboxylate Superplasticizer (Slump Retaining) – 50% Solid Liquid

Introducing the BT-302 Polycarboxylate Superplasticizer (slump retaining), a cutting-edge innovation from Shandong Gaoqiang New Material Technology Co., LTD. This new-age polycarboxylate superplasticizer is crafted using an advanced mother liquor, developed through our strategic partnership with leading polyether manufacturers. Enhanced by imported additives, the synthesis process features a novel catalyst and an expertly engineered control system, ensuring a scientifically optimized molecular structure.

At Gaoqiang, we understand diverse customer requirements, which is why we have meticulously designed a state-of-the-art polycarboxylate-based superplasticizer. This slump-retaining marvel not only retains slump but also showcases impressive dispersibility. Rooted in the principles of slump loss in freshly mixed concrete, our design leverages insights from post-addition superplasticizers and pioneering research on reactive polymers. By altering admixture adsorption behaviors and tailoring polymer structures, we offer a product akin to graft copolymer admixtures. However, ours feature elongated graft side chains, reduced carboxyl group ratios, and strategically placed ester cross-linking points.

The ingenious design of our product incorporates long polyethylene glycol side chains, delivering exceptional steric hindrance effects that decelerate cement particle aggregation. A minimal polymer presence at the cement-water interface ensures dispersibility, while the ester cross-linking points in the copolymer gradually hydrolyze in the alkaline environment, releasing low molecular weight copolymers into the system. This process effectively counteracts superplasticizer consumption by C3A and C4AF, maintaining its critical micelle state and halting significant slump loss.

Performance Characteristics:

(1) Experience no slump loss after an hour, with over 80% of the initial slump preserved after 2 hours. This superior performance addresses rapid slump loss issues in concrete, meeting stringent retention requirements under specialized conditions.
(2) Benefit from the superb workability of concrete, characterized by high fluidity, ease of pouring and compacting. This effectively lowers concrete viscosity, making it ideal for pumping applications.
(3) Prioritizing environmental responsibility, our production process generates no wastewater, waste gas, or waste residue.
(4) Demonstrates vast compatibility with various cement types, including Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and diverse admixtures.

Usage Guidelines:

(1) For optimal results, we recommend an experimental dosage of 0.5% - 1.0% by cementitious material weight. Tailor the dosage through testing based on cement and aggregate characteristics.
(2) The superplasticizer is versatile, dissolvable in water, and compatible with other additives. For best results, consider adding it post-compounding directly into the concrete mix.
(3) Perfectly combinable with various retarders and slump retention agents, but avoid mixing with fatty acids, naphthalene-based, amino-based, or ion-based additives to maintain performance integrity.
(4) Our expert technical team is on hand to provide comprehensive on-site guidance for optimal usage and compounding.
