Product Description

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

The BT-302 Polycarboxylate Superplasticizer (slump retaining) represents a pioneering achievement in concrete admixture technology. Developed by Shandong Gaoqiang New Material Technology Co., LTD., this cutting-edge superplasticizer combines the advanced polycarboxylate superplasticizer mother liquor with premium imported additives. Our synthesis process, in technical collaboration with leading polyether manufacturers, introduces a revolutionary new catalyst and control system, all underpinned by a scientifically crafted molecular structure.

Gaoqiang's innovative polycarboxylate-based superplasticizer is meticulously engineered to cater to diverse customer needs, offering unmatched slump retention with optimal dispersibility. Inspired by in-depth research on slump loss dynamics in freshly mixed concrete, this breakthrough design leverages post-addition superplasticizer methodologies and reactive polymer insights. By altering admixture adsorption behavior and crafting a corresponding polymer structure, this product emulates graft copolymer admixtures with its elongated graft side chains, reduced carboxyl group ratios, and strategic ester cross-linking points.

The copolymer's extended polyethylene glycol side chains furnish substantial steric hindrance, effectively decelerating cement particle aggregation. A strategic polymer adsorption at the cement-water interface ensures requisite dispersibility. Within the alkaline cement milieu, the copolymer's ester cross-linking points undergo hydrolysis, systematically releasing low molecular weight copolymers with superior dispersing attributes into the cement-water matrix. This innovative mechanism compensates for superplasticizer consumption by C3A and C4AF, sustaining the superplasticizer's critical micelle state, and mitigating significant slump loss.

Performance Characteristics:

(1) Exceptional slump retention: Maintain zero slump loss after 1 hour and preserve over 80% of the initial slump after 2 hours, efficiently addressing rapid slump loss challenges in concrete under specialized conditions.
(2) Superior concrete performance: Boasting high fluidity for effortless pouring and compacting, this superplasticizer effectively reduces concrete viscosity, making it ideal for pumping applications.
(3) Eco-conscious production: Demonstrating our commitment to sustainability, the production process is clean and green, generating no waste water, waste gas, or waste residues.
(4) Unmatched versatility: Our formulation exhibits exceptional compatibility with a wide range of cements and admixtures, including Portland, ordinary Portland, slag Portland, fly ash, *** ash cement, and more.

Usage Guidelines:

(1) For optimal results, begin with a recommended experimental dosage of 0.5% - 1.0% by weight of cementitious material. Tailor the dosage through testing, considering the unique characteristics of cement, aggregates, and other variables.
(2) Flexibility in application: Dissolve the superplasticizer in water and blend with other additives, or add directly into the concrete mix. For best results, incorporate it post-compounding.
(3) Compatible with various retarders and slump retention agents, but avoid mixing with fatty acids, naphthalene-based, amino-based, or ion-based additives to preserve performance integrity.
(4) Our dedicated technical team offers comprehensive on-site guidance to ensure proper usage and compounding for your specific needs.
