Product Description

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

BT-302 Polycarboxylate Superplasticizer (slump retaining) represents a groundbreaking development in advanced construction chemistry. Crafted from Shandong Gaoqiang New Material Technology Co., Ltd.'s pioneering polycarboxylate superplasticizer mother liquor, this product integrates state-of-the-art imported additives. The synthesis process is a result of strategic technical collaboration with leading polyether manufacturers, yielding a sophisticated catalyst and control system that features a meticulously engineered molecular structure.

To cater to diverse client requirements, Gaoqiang proudly presents a revolutionary polycarboxylate-based superplasticizer (slump retaining), engineered for superior slump retention and exceptional dispersibility. Rooted in a profound understanding of slump loss dynamics in fresh concrete, this innovation draws from advanced superplasticizer post-addition techniques and cutting-edge reactive polymer research. By strategically altering admixture adsorption behavior and meticulously designing its polymer structure, this product mirrors graft copolymer admixtures while boasting longer graft side chains, reduced carboxyl group ratios, and ester cross-linking points for unparalleled performance.

The copolymer's extended polyethylene glycol side chains impart significant steric hindrance, effectively decelerating the physical aggregation of cement particles. Even with minimal polymer adsorption at the cement-water interface, it ensures notable dispersibility. In alkaline cement environments, the copolymer's ester cross-linking points undergo hydrolysis, gradually releasing dispersing-capable low molecular weight copolymers into the cement-water milieu. This innovative supplementation counterbalances superplasticizer consumption due to C3A and C4AF, maintaining the superplasticizer in a critical micelle state and effectively preventing substantial slump loss.

Performance Characteristics:

(1) Remarkably, there is no slump loss after 1 hour, with over 80% of the initial slump retained after 2 hours. This effectively addresses the challenge of rapid slump loss, ensuring compliance with stringent slump retention requirements even under specific conditions.
(2) The concrete's operational excellence is unmatched, showcasing high fluidity for seamless pouring and compacting. This product significantly reduces concrete viscosity, making it ideal for efficient pumping.
(3) Environmentally conscious, the production process generates no wastewater, waste gas, or residue, aligning with sustainable practices.
(4) Exhibits extensive compatibility with Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and a wide range of admixtures.

Usage Guidelines:

(1) For optimal results, a recommended experimental dosage is 0.5% - 1.0% (by weight of cementitious material). It is advisable to determine the precise dosage through testing, considering the specific characteristics of cement and aggregates.
(2) The superplasticizer is versatile, either dissolvable in water and combinable with other additives, or directly incorporable into concrete mixtures. For best results, it is recommended to add post-compounding.
(3) Compatible with various retarders and slump retention agents, but should not be mixed with fatty acids, naphthalene-based, amino-based, or ion-based additives to preserve its superior performance.
(4) Our expert technical team is readily available to provide on-site guidance for optimal usage and compounding.
