Product Description

BT-302 Polycarboxylate Superplasticizer – Slump Retaining of 50% in liquid form

BT-302 Polycarboxylate Superplasticizer (slump retaining) represents a groundbreaking advancement in superplasticizer technology. Meticulously crafted by Shandong Gaoqiang New Material Technology Co., Ltd., this product is a sophisticated blend of a newly developed polycarboxylate superplasticizer mother liquor, combined with premium imported additives. Through strategic partnerships with leading polyether manufacturers, we've pioneered an advanced catalyst and control system, culminating in a scientifically engineered molecular structure.

Gaoqiang is proud to introduce a revolutionary polycarboxylate-based superplasticizer designed to meet diverse customer demands. This innovative product excels in maintaining slump retention while offering exceptional dispersibility. By delving into the mechanisms of slump loss in freshly mixed concrete, we have developed a superior approach that integrates both post-addition superplasticizer methods and in-depth research on reactive polymers. Our strategy involves tailoring the adsorption behavior of admixtures and crafting a specifically designed polymer structure. The result is a product that boasts a chemical structure akin to graft copolymer admixtures, distinguished by extended graft side chains, reduced carboxyl group ratios, and strategically placed ester cross-linking points within the copolymer framework.

Harnessing the power of extended polyethylene glycol side chains, our copolymer molecules deliver remarkable steric hindrance effects, effectively mitigating the physical aggregation of cement particles. This innovative design ensures a modest adsorption of polymers at the cement-water interface, imparting significant dispersibility. The strategic ester cross-linking points within the copolymer molecules undergo hydrolysis in an alkaline cement environment, progressively releasing low molecular weight copolymers imbued with dispersing capabilities into the cement-water mixture. This dynamic supplementation counteracts the consumption of superplasticizer by C3A and C4AF, preserving the superplasticizer's critical micelle state and averting drastic slump loss.

Performance Characteristics:

1. Exceptional Slump Retention: Experience no slump loss after 1 hour, with an impressive retention rate of over 80% of initial slump after 2 hours. This feature addresses the challenge of rapid slump loss in concrete, ensuring compliance with slump retention demands under specialized conditions.
2. Superior Workability: The concrete produced boasts outstanding fluidity, facilitating effortless pouring and compacting, significantly reducing viscosity, and proving ideal for pumping applications.
3. Eco-Conscious Production: Our environmentally friendly process generates no wastewater, waste gas, or waste residue, aligning with sustainable production principles.
4. Versatile Compatibility: This product is remarkably adaptable, suitable for use with Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and a wide array of admixtures.

Usage Guidelines:

(1) It is recommended to experiment with a dosage ranging from 0.5% to 1.0% by weight of cementitious material. The optimal amount should be determined through testing, taking into account the specific characteristics of cement and aggregates.
(2) The superplasticizer is versatile in application, either dissolvable in water and compatible with other additives, or directly incorporated into concrete mixtures. For optimal results, it is advised to add it post-compounding.
(3) This product can be effectively combined with various retarders and slump retention agents. However, it is not recommended to mix with fatty acids, naphthalene-based, amino-based, or ion-based additives, as they may compromise performance.
(4) Our dedicated technical team offers on-site guidance to ensure the correct usage and compounding of this product.
