Product Description

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

BT-302 Polycarboxylate Superplasticizer (slump retaining) is an innovative blend of polycarboxylate superplasticizer, crafted from the pioneering mother liquor developed by Shandong Gaoqiang New Material Technology Co., LTD., enriched with premium imported additives. Our advanced synthesis process, executed in collaboration with leading polyether manufacturers, has resulted in a groundbreaking catalyst and control system, featuring a scientifically engineered molecular structure that elevates performance.

In response to diverse customer requirements, Gaoqiang has engineered a cutting-edge polycarboxylate-based superplasticizer (slump retaining) that excels in retaining slump while providing exceptional dispersibility. Drawing upon the principles of slump loss in freshly mixed concrete, this product merges insights from post-addition superplasticizer methods and reactive polymer research. By altering admixture adsorption behavior and crafting a precisely tailored polymer structure, this superplasticizer mirrors the chemical structure of graft copolymer admixtures, enhanced by longer graft side chains, reduced carboxyl group ratios, and strategic ester cross-linking points within the copolymer matrix.

The extended polyethylene glycol side chains within the copolymer molecules deliver robust steric hindrance, effectively decelerating the physical aggregation of cement particles. A minimal polymer presence at the cement-water interface ensures optimal dispersibility. As the ester cross-linking points hydrolyze within the alkaline cement environment, they release low molecular weight copolymers with dispersing capabilities into the cement-water matrix, offsetting superplasticizer consumption due to C3A and C4AF interactions, sustaining it in a critical micelle state to avert significant slump loss.

Performance Characteristics:

(1) Experience zero slump loss after 1 hour, with a remarkable retention of over 80% of the initial slump after 2 hours, effectively addressing the challenge of rapid slump loss in concrete and fulfilling slump retention requirements under specialized conditions.
(2) Benefit from superior concrete workability, high fluidity, and effortless pouring and compaction, which significantly reduces concrete viscosity and enhances suitability for pumping applications.
(3) Eco-friendly production ensures no discharge of wastewater, waste gas, or residues, highlighting our commitment to sustainability.
(4) Versatile adaptability to Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and a wide range of admixtures.

Usage Guidelines:

(1) For experimentation, a dosage of 0.5% - 1.0% (by weight of cementitious material) is recommended. Determine the optimal dosage through testing, considering the specific characteristics of cement, aggregates, and other variables.
(2) The superplasticizer can be dissolved in water and combined with other additives, or directly incorporated into the concrete mix. For optimal results, it is recommended to add it post-compounding.
(3) Compatible with a variety of retarders and slump retention agents. Avoid mixing with fatty acids, naphthalene-based, amino-based, or ion-based additives to maintain superior performance.
(4) Our dedicated technical team offers on-site guidance to ensure proper usage and effective compounding.
