Product Description

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

BT-302 Polycarboxylate Superplasticizer (slump retaining) represents a groundbreaking advancement in concrete technology. Engineered by Shandong Gaoqiang New Material Technology Co., Ltd., this innovative superplasticizer is crafted using a state-of-the-art polycarboxylate superplasticizer mother liquor, complemented by premium imported additives. Our synthesis process benefits from strategic collaboration with leading polyether manufacturers, resulting in the development of a pioneering catalyst and an advanced control system, meticulously designed with a scientifically optimized molecular structure.

Gaoqiang has meticulously crafted a versatile polycarboxylate-based superplasticizer with exceptional slump retention and dispersibility, tailored to diverse customer requirements. This innovation draws upon the latest insights into slump loss in freshly mixed concrete, integrating advanced post-addition superplasticizer techniques and cutting-edge reactive polymer research. Our approach involves precision modification of admixture adsorption behaviors and strategic polymer structure design, resulting in a product akin to graft copolymer admixtures, yet distinguished by extended graft side chains, reduced carboxyl group ratios, and ester cross-linking points within the copolymer architecture.

The copolymer's extended polyethylene glycol side chains introduce significant steric hindrance, effectively decelerating cement particle aggregation. Minimal polymer adsorption at the cement-water interface ensures dispersibility. Ester cross-linking points undergo hydrolysis in alkaline cement environments, progressively releasing low molecular weight copolymers that enhance dispersion within the cement-water matrix. This innovative mechanism offsets superplasticizer depletion from C3A and C4AF interactions, sustaining a critical micelle state and averting detrimental slump loss.

Performance Characteristics:

(1) Unparalleled slump retention: maintains initial slump with no loss after 1 hour, retaining over 80% of initial slump after 2 hours. This exceptional performance addresses the persistent challenge of rapid slump loss in concrete, ensuring optimal slump retention even under demanding conditions.
(2) Superior concrete workability: offers high fluidity for effortless pouring and compaction, significantly reducing concrete viscosity. Ideal for pumping applications.
(3) Eco-conscious production: environmentally friendly with zero waste water, waste gas, or waste residue during manufacturing.
(4) Exceptional compatibility: seamlessly integrates with Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and an array of admixtures.

Usage Guidelines:

(1) Optimal dosage ranges from 0.5% to 1.0% by weight of cementitious material. Conduct thorough testing to determine the ideal dosage, taking into account the specific characteristics of cement, aggregates, and other materials.
(2) The superplasticizer can be seamlessly dissolved in water and combined with other additives, or directly introduced into the concrete mix. For best results, we recommend adding it post-compounding.
(3) Compatible with various retarders and slump retention agents. Avoid mixing with fatty acids, naphthalene-based, amino-based, or ion-based additives to preserve optimal performance.
(4) Our expert technical team is available to provide on-site guidance for precise usage and compounding, ensuring optimal results.
