Product Description

 BT-302,  Polycarboxylate Superplasticizer slump retention solid content of 50% Liquid

BT-302 Polycarboxylate Superplasticizer (slump retaining) stands as a testament to innovation, crafted from a novel polycarboxylate superplasticizer mother liquor. Developed by Shandong Gaoqiang New Material Technology Co., LTD, in collaboration with top-tier polyether manufacturers, it integrates imported additives and a newly engineered catalyst and control system. This synthesis boasts a scientifically crafted molecular structure, ensuring unparalleled performance.

Gaoqiang has ingeniously engineered a revolutionary polycarboxylate-based superplasticizer, tailored for diverse customer needs. This advanced formulation excels in slump retention while offering remarkable dispersibility. Drawing from the dynamics of freshly mixed concrete slump loss, and informed by cutting-edge superplasticizer post-addition techniques and reactive polymer studies, this product redefines adsorption behavior. Its polymer structure, characterized by elongated graft side chains, reduced carboxyl group ratios, and strategic ester cross-linking, mirrors graft copolymer admixtures, unlocking superior performance.

The innovative copolymer molecules, endowed with extended polyethylene glycol side chains, deliver powerful steric hindrance, effectively mitigating cement particle aggregation. As the ester cross-linking points undergo hydrolysis in the alkaline cement environment, they gradually liberate low molecular weight copolymers. These copolymers seamlessly integrate into the cement-water matrix, enhancing dispersibility and compensating for superplasticizer consumption by C3A and C4AF. This process ensures the superplasticizer remains in a critical micelle state, safeguarding against significant slump loss.

Performance Characteristics:

(1) Experience zero slump loss after one hour, with over 80% of the initial slump preserved even after two hours. This innovation effectively addresses rapid slump loss challenges, meeting stringent slump retention requirements in specialized conditions.
(2) Exceptional concrete workability is guaranteed, with high fluidity that facilitates easy pouring and compacting. The viscosity of concrete is significantly reduced, making it ideal for pumping operations.
(3) Embrace environmental responsibility with this product, as its production process generates no waste water, waste gas, or residue, marking a sustainable choice for the industry.
(4) Enjoy broad compatibility across a spectrum of cement types, including Portland cement, ordinary Portland cement, slag Portland cement, fly ash cement, *** ash cement, and various admixtures.

Usage Guidelines:

(1) For optimal results, experiment with a recommended dosage of 0.5% - 1.0% by weight of cementitious material. Tailor the dosage to the specific characteristics of cement, aggregates, etc., through precise testing.
(2) Versatile in application, this superplasticizer can be dissolved in water and combined with other additives, or directly added to concrete for mixing. For best results, incorporate after compounding.
(3) Seamlessly compatible with a variety of retarders and slump retention agents, yet it's advised to avoid mixing with fatty acids, naphthalene-based, amino-based, or ion-based additives to preserve optimal performance.
(4) Benefit from our expert technical team, offering on-site guidance for the correct usage and compounding of this product.
