Product Description

 BT-302 Polycarboxylate Superplasticizer (Slump Retaining) 50% solid liquid

Introducing BT-302 Polycarboxylate Superplasticizer (slump retaining), a remarkable advancement in admixture technology crafted by Shandong Gaoqiang New Material Technology Co., LTD. This cutting-edge product blends the groundbreaking polycarboxylate superplasticizer mother liquor with premium imported additives. The synthesis process, refined through collaboration with leading polyether manufacturers, features a novel catalyst and a meticulously engineered control system, showcasing a scientifically designed molecular structure for optimal performance.

To cater to diverse customer demands, Gaoqiang presents the innovative polycarboxylate-based superplasticizer (slump retaining), masterfully designed to balance slump retention and dispersibility. This forward-thinking solution addresses slump loss in freshly mixed concrete, leveraging superplasticizer post-addition strategies and insights into reactive polymers. By altering admixture adsorption behaviors and crafting an advanced polymer structure, this product mirrors graft copolymer admixtures, yet stands out with extended graft side chains, reduced carboxyl group ratios, and strategically placed ester cross-linking points.

The copolymer's extended polyethylene glycol side chains offer remarkable steric hindrance, effectively decelerating cement particle aggregation. At the cement-water interface, minimal polymer adsorption ensures essential dispersibility. In the alkaline cement milieu, ester cross-linking points initiate hydrolysis, releasing low molecular weight copolymers with enhanced dispersing capabilities into the cement-water matrix. This process offsets superplasticizer depletion by C3A and C4AF, maintaining the superplasticizer's critical micelle state and averting significant slump loss.

Unveiling Performance Characteristics:

(1) Experience zero slump loss after 1 hour and retain over 80% of the initial slump after 2 hours, effectively tackling rapid slump loss and fulfilling slump retention requisites under special conditions.
(2) Achieve exceptional concrete workability with high fluidity, simplifying pouring and compacting processes while reducing concrete viscosity, ideal for efficient pumping operations.
(3) Committed to sustainability, our production process generates no waste water, waste gas, or waste residue, ensuring an environmentally friendly solution.
(4) Offers remarkable versatility, adapting seamlessly to Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and various admixtures.

Comprehensive Usage Guidelines:

(1) Initiate with a recommended dosage range of 0.5% - 1.0% by cementitious material weight, determining the optimal amount through testing based on cement and aggregate characteristics.
(2) The superplasticizer is versatile: dissolve in water and blend with other additives or directly incorporate into concrete. For best results, add post-compounding.
(3) Harmoniously combine with various retarders and slump retention agents. Avoid mixing with fatty acids, naphthalene-based, amino-based, or ion-based additives to maintain peak performance.
(4) Benefit from our expert technical team providing on-site guidance for optimal usage and compounding.
