Product Description

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

Introducing the BT-302 Polycarboxylate Superplasticizer (slump retaining), a pioneering advancement in concrete technology. Crafted meticulously by Shandong Gaoqiang New Material Technology Co., Ltd., this innovative superplasticizer features a state-of-the-art polycarboxylate mother liquor, enhanced with premium imported additives. The development process involves strategic collaboration with leading polyether manufacturers, culminating in a revolutionary catalyst and control system that boasts a scientifically engineered molecular structure.

In response to the evolving needs of our clientele, Gaoqiang proudly presents a cutting-edge polycarboxylate-based superplasticizer designed specifically for slump retention while maintaining superior dispersibility. Drawing inspiration from the dynamics of slump loss in freshly mixed concrete and advanced studies on reactive polymers, this product redefines admixture adsorption behavior through a uniquely crafted polymer structure. Featuring a chemical architecture akin to graft copolymer admixtures, it showcases extended graft side chains, optimized carboxyl group ratios, and strategically positioned ester cross-linking points.

The innovative copolymer molecules, adorned with elongated polyethylene glycol side chains, deliver robust steric hindrance, effectively mitigating cement particle aggregation. By adsorbing minimally at the cement-water interface, it ensures a balanced dispersibility. The ester cross-linking points, upon interaction with the alkaline cement medium, gradually hydrolyze, releasing low molecular weight copolymers that enhance dispersion within the cement-water matrix. This dynamic process counteracts the superplasticizer's consumption by C3A and C4AF, maintaining its efficacy by preserving its critical micelle state, thereby preventing notable slump loss.

Performance Characteristics:

(1) Experience no slump loss after an hour, with an impressive retention of over 80% of the initial slump after two hours. This innovation addresses the challenge of rapid slump loss, fulfilling specific slump retention requirements under demanding conditions.
(2) Achieve outstanding concrete workability with high fluidity, facilitating effortless pouring and compacting, while significantly minimizing concrete viscosity, making it ideal for efficient pumping applications.
(3) Our production process is environmentally friendly, ensuring no generation of wastewater, waste gas, or waste residue, aligning with sustainable practices.
(4) Demonstrates exceptional adaptability to a wide range of cements, including Portland, ordinary Portland, slag Portland, fly ash, and *** ash cement, as well as diverse admixtures.

Usage Guidelines:

(1) For optimal results, an experimental dosage of 0.5% - 1.0% by weight of cementitious material is recommended. Fine-tuning of dosage is advised based on specific cement and aggregate characteristics.
(2) This superplasticizer can be dissolved in water and combined with other additives, or added directly to concrete mixes. For best results, it is recommended to incorporate it post-compounding.
(3) Compatible with various retarders and slump retention agents. However, it is advisable to avoid mixing with fatty acids, naphthalene-based, amino-based, or ion-based additives to preserve performance integrity.
(4) Our expert technical team offers comprehensive on-site guidance to ensure optimal usage and compounding techniques.
