Product Description

BT-302 Polycarboxylate Superplasticizer slump retention  50% solid content in liquid form

Experience the innovation of BT-302 Polycarboxylate Superplasticizer (slump retaining), a groundbreaking product crafted by Shandong Gaoqiang New Material Technology Co., Ltd. This advanced superplasticizer is formulated with a novel polycarboxylate mother liquor, developed in collaboration with leading polyether manufacturers. With cutting-edge imported additives and a scientifically engineered molecular structure, this product leverages a breakthrough catalyst and control system for unparalleled performance.

Shandong Gaoqiang has ingeniously engineered a new polycarboxylate-based superplasticizer that excels in both slump retention and dispersibility, tailored to satisfy diverse customer requirements. This product draws inspiration from slump loss mechanisms in freshly mixed concrete, integrating insights from superplasticizer post-addition techniques and reactive polymer research. By redefining admixture adsorption behavior and innovatively designing polymer structures, this superplasticizer mimics graft copolymer admixtures with enhanced features like longer graft side chains, minimized carboxyl ratios, and ester cross-linking points.

The sophisticated design of this superplasticizer includes elongated polyethylene glycol side chains that offer steric hindrance effects, effectively mitigating cement particle aggregation. The copolymer's ester cross-linking points hydrolyze in the alkaline cement environment, gradually releasing dispersing low molecular weight copolymers into the cement-water matrix. This ensures continuous superplasticizer availability by counteracting C3A and C4AF consumption, maintaining critical micelle states, and preventing substantial slump loss.

Exceptional Performance Characteristics:

(1) Remarkably, this product ensures no slump loss after 1 hour, with more than 80% of the original slump preserved after 2 hours, addressing rapid slump loss challenges and fulfilling specific retention needs.
(2) Enjoy superior concrete workability and fluidity, facilitating easy pouring and compaction while significantly reducing viscosity, making it ideal for efficient pumping applications.
(3) This eco-friendly product ensures a sustainable production process with no wastewater, exhaust, or residue generation, aligning with modern environmental standards.
(4) Exhibits broad compatibility with Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and various admixtures, showcasing its versatile adaptability.
