Product Description

 BT-302 Polycarboxylate Superplasticizer (Slump Retaining) solid content of 50% in liquid form

The BT-302 Polycarboxylate Superplasticizer (slump retaining) is an innovative, cutting-edge additive engineered by Shandong Gaoqiang New Material Technology Co., LTD. This superplasticizer is crafted from a pioneering polycarboxylate mother liquor and select imported additives. Our synthesis process benefits from strategic technical partnerships with leading polyether manufacturers, resulting in a newly developed catalyst and a sophisticated control system with a meticulously engineered molecular structure.

To cater to diverse customer demands, Gaoqiang has skillfully designed a novel polycarboxylate-based superplasticizer (slump retaining). This product not only retains slump effectively but also exhibits remarkable dispersibility. Drawing on the principles of slump loss in freshly mixed concrete, our design integrates insights from post-addition superplasticizer methods and reactive polymer research. By altering the adsorption behavior of admixtures and crafting a precise polymer structure, we deliver a product that mirrors graft copolymer admixtures. It features extended graft side chains, reduced carboxyl group ratios, and ester cross-linking points within its copolymer framework.

Featuring extended polyethylene glycol side chains, our copolymer molecules create a steric hindrance effect, mitigating the physical aggregation of cement particles. A minimal polymer presence at the cement-water interface offers optimal dispersibility. The ester cross-linking points within the copolymer undergo hydrolysis in alkaline cement environments, progressively releasing low molecular weight copolymers with dispersing capabilities into the cement-water matrix. This compensates for superplasticizer consumption by C3A and C4AF, maintaining the product in a critical micelle state and effectively preventing significant slump loss.

Performance Characteristics:

(1) Experience no slump loss after 1 hour and retain over 80% of the initial slump after 2 hours. This remarkable feature addresses the common challenge of rapid slump loss in concrete, ensuring slump retention even under special conditions.
(2) Enjoy exceptional concrete workability, characterized by high fluidity, ease of pouring, and efficient compaction. Effectively reduces concrete viscosity, making it ideal for pumping applications.
(3) Environmentally sustainable, with no wastewater, gas emissions, or waste residue generated during production, aligning with eco-friendly practices.
(4) Versatile compatibility with Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and a variety of admixtures.

Usage Guidelines:

(1) For experimental purposes, a recommended dosage of 0.5% - 1.0% (based on the weight of cementitious materials) is advised. Optimal dosage should be determined through testing, tailored to the specific characteristics of the cement and aggregates used.
(2) The superplasticizer can be seamlessly dissolved in water and combined with other additives, or directly introduced into the concrete mix. It is recommended to add it post-compounding for best results.
(3) Compatible for use with various retarders and slump retention agents. However, 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, ensuring proper usage and efficient compounding for optimal results.
