Product Description

Product Name: BT-302 Polycarboxylate Superplasticizer (Slump Retaining) Available as 50% Solid Liquid

Introducing the BT-302 Polycarboxylate Superplasticizer (slump retaining), an innovative solution meticulously crafted by Shandong Gaoqiang New Material Technology Co., LTD. This groundbreaking superplasticizer integrates an advanced mother liquor, developed in partnership with prominent polyether manufacturers. It boasts a novel catalyst and control system, all scientifically engineered with precision molecular design. Additionally, it incorporates imported, high-quality additives to enhance its performance.

Gaoqiang proudly presents an advanced polycarboxylate-based superplasticizer, specifically engineered for diverse customer needs. This unique product excels in retaining slump and ensuring optimal dispersibility. It leverages comprehensive research into slump loss in freshly mixed concrete, drawing insights from post-addition superplasticizer methods and reactive polymer studies. Through innovative design, this superplasticizer transforms admixture adsorption behavior with a tailored polymer structure, featuring longer graft side chains, reduced carboxyl group ratios, and strategic ester cross-linking points.

The copolymer's elongated polyethylene glycol side chains create steric hindrance, effectively mitigating cement particle aggregation. With minimal polymer adsorption at the cement-water interface, it maintains impressive dispersibility. The copolymer structure's ester cross-linking points hydrolyze in alkaline cement environments, steadily releasing low molecular weight copolymers that enhance dispersibility. This innovative supplementation counters superplasticizer consumption from C3A and C4AF, sustaining a critical micelle state and reliably preventing slump loss.

Key Performance Characteristics:

(1) Unparalleled slump retention: After 1 hour, no slump loss; after 2 hours, over 80% of the initial slump is retained. This effectively addresses rapid slump loss challenges in concrete, meeting stringent slump retention demands under unique conditions.
(2) Superior workability of concrete: High fluidity ensures easy pouring and compacting. The product significantly reduces concrete viscosity, making it ideal for pumping applications.
(3) Eco-friendly production: No wastewater, waste gas, or waste residue is generated during the manufacturing process, ensuring an environmentally sustainable product.
(4) Versatile compatibility: Suitable for Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and various admixtures, showcasing remarkable adaptability.

Expert Usage Guidelines:

(1) For experimental applications, a recommended dosage of 0.5% - 1.0% (by weight of cementitious material) is advised. Optimal dosage should be verified through testing, considering cement, aggregate characteristics, and other factors.
(2) This superplasticizer can be dissolved in water for compounding with other additives or directly added to concrete mixes. It is recommended to incorporate it after compounding for optimal results.
(3) Compatible with various retarders and slump retention agents. However, it should not be mixed with fatty acids, naphthalene-based, amino-based, or ion-based additives to prevent performance compromise.
(4) Our dedicated technical team offers on-site guidance for appropriate usage and compounding, ensuring optimal product performance.
