Product Description

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

Introducing the revolutionary BT-302 Polycarboxylate Superplasticizer (slump retaining), a trailblazing formulation crafted by the esteemed Shandong Gaoqiang New Material Technology Co., LTD. This innovative product is a harmonious blend of our proprietary polycarboxylate superplasticizer mother liquor and premium imported additives. Developed in collaboration with leading polyether manufacturers, our synthesis process boasts a cutting-edge catalyst and an expertly engineered control system, all designed with a meticulously planned molecular structure for unmatched performance.

Gaoqiang proudly presents a meticulously engineered polycarboxylate-based superplasticizer (slump retaining) tailored to cater to diverse customer requirements. This advanced formulation not only retains slump but also exhibits superior dispersibility. Rooted in the principles of slump loss in freshly mixed concrete, our product embodies the essence of both post-addition superplasticizers and reactive polymer research. By innovatively altering the adsorption behavior of admixtures and crafting a bespoke polymer structure, we have achieved a chemical marvel akin to graft copolymer admixtures. With elongated graft side chains, reduced carboxyl group ratios, and ester cross-linking points, our product stands as a pinnacle of chemical ingenuity.

Our product's long polyethylene glycol side chains create a robust steric hindrance effect, effectively decelerating the physical aggregation of cement particles. A carefully calibrated polymer adsorption at the cement-water interface ensures a remarkable level of dispersibility. The strategically positioned ester cross-linking points undergo hydrolysis in the alkaline cement medium, releasing low molecular weight copolymers into the system. This ingenious process compensates for superplasticizer consumption by C3A and C4AF, maintaining the superplasticizer in a critical micelle state and effectively preventing slump loss.

Performance Characteristics:

(1) Experience no slump loss after 1 hour, with over 80% of the initial slump retained after 2 hours. This effectively resolves the challenge of rapid slump loss in concrete, meeting the stringent requirements for slump retention under specialized conditions.
(2) Enjoy excellent workability with high fluidity for easy pouring and compacting. The BT-302 significantly reduces concrete viscosity, making it ideal for efficient pumping applications.
(3) Environmentally conscious production ensures no waste water, gas, or residue is generated, aligning with green manufacturing standards.
(4) Our product demonstrates exceptional adaptability across a wide range of cements, including Portland, ordinary Portland, slag Portland, fly ash, *** ash, and various admixtures.

Usage Guidelines:

(1) For optimal results, we recommend an experimental dosage of 0.5% - 1.0% by weight of cementitious material. Determine the best dosage through meticulous testing, considering cement and aggregate characteristics.
(2) The superplasticizer can seamlessly dissolve in water and blend with other additives, or be directly mixed into concrete. For best results, add post-compounding.
(3) Versatile compatibility with various retarders and slump retention agents. 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 for optimal usage and compounding practices.
