Product Description

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

Introducing the revolutionary BT-302 Polycarboxylate Superplasticizer (slump retaining), a groundbreaking innovation by Shandong Gaoqiang New Material Technology Co., Ltd. This advanced superplasticizer is crafted from a novel polycarboxylate mother liquor, enhanced with premium imported additives. Through strategic collaboration with leading polyether manufacturers, a pioneering catalyst and cutting-edge control system have been developed, featuring a meticulously engineered molecular structure for superior performance.

Gaoqiang proudly presents a state-of-the-art polycarboxylate-based superplasticizer (slump retaining) designed to address diverse customer demands. This innovative solution excels in slump retention and dispersibility, grounded in comprehensive research on fresh concrete slump loss. By adjusting the adsorption dynamics of admixtures and crafting a bespoke polymer structure, this product mirrors graft copolymer admixtures but boasts extended graft side chains, reduced carboxyl group ratios, and strategic ester cross-linking points.

The ingenious design of the copolymer molecules, with elongated polyethylene glycol side chains, introduces steric hindrance that decelerates cement particle aggregation. A modest polymer presence at the cement-water interface enhances dispersibility. Furthermore, in the alkaline cement medium, ester cross-linking points undergo hydrolysis, progressively releasing low molecular weight copolymers that maintain the superplasticizer in its critical micelle state, counteracting significant slump loss by compensating for C3A and C4AF consumption.

Performance Characteristics:

(1) Exceptional retention abilities: No slump loss after 1 hour, retaining over 80% of the initial slump after 2 hours, effectively mitigating rapid slump loss in concrete, especially under demanding conditions.
(2) Superior concrete performance: High fluidity ensures effortless pouring and compacting, substantially decreasing concrete viscosity, making it ideal for efficient pumping applications.
(3) Environmentally conscious production: The process generates no wastewater, waste gas, or waste residue, aligning with eco-friendly practices.
(4) Versatile adaptability: Compatible with Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and a broad spectrum of admixtures.

Usage Guidelines:

(1) Experimentation recommended dosage ranges from 0.5% to 1.0% (by weight of cementitious material). Optimal dosage should be tailored through rigorous testing considering specific cement and aggregate characteristics.
(2) For maximum efficiency, dissolve the superplasticizer in water and blend with other additives, or introduce it directly into the concrete mix. Preferably, add after compounding for best results.
(3) Compatible with various retarders and slump retention agents. Avoid mixing with fatty acids, naphthalene-based, amino-based, or ion-based additives to preserve performance integrity.
(4) Our expert technical team is available to provide on-site guidance for optimal usage and precise compounding.
