Product Description

 BT-302 Polycarboxylate Superplasticizer slump retention 50% solid liquid 

The BT-302 Polycarboxylate Superplasticizer is a groundbreaking innovation—a true masterpiece of chemical engineering. Developed by Shandong Gaoqiang New Material Technology Co., Ltd., this superplasticizer incorporates the latest advancements in polycarboxylate technology. By leveraging high-quality imported additives and forging significant technical partnerships with leading polyether manufacturers, we have crafted a new catalyst and control system. The scientifically designed molecular structure ensures unparalleled efficiency and effectiveness.

Gaoqiang proudly presents a revolutionary polycarboxylate-based superplasticizer designed to cater to diverse customer needs. This cutting-edge formulation not only excels in slump retention but also offers remarkable dispersibility. By drawing inspiration from advanced research in reactive polymers and innovative post-addition methods, we have redefined the adsorption behavior of admixtures. The result is a polymer with a unique structure, akin to graft copolymer admixtures but boasting longer graft side chains, reduced carboxyl group ratios, and strategic ester cross-linking points. This ensures optimal performance and longevity.

Our superplasticizer's long polyethylene glycol side chains deliver exceptional steric hindrance effects, decelerating cement particle aggregation. The strategic inclusion of ester cross-linking points allows for gradual hydrolysis within alkaline cement environments, releasing copolymers with potent dispersing functionality. This dynamic system compensates for superplasticizer consumption by C3A and C4AF, ensuring the maintenance of a critical micelle state and significantly minimizing slump loss.

Performance Characteristics:

(1) Unmatched slump retention—0% loss after 1 hour, and over 80% retention after 2 hours. This innovative solution effectively tackles rapid slump loss challenges, meeting stringent retention requirements even under demanding conditions.
(2) Superior workability with high fluidity—our superplasticizer ensures effortless pouring and compacting, dramatically reducing concrete viscosity and optimizing it for efficient pumping operations.
(3) Environmentally conscious production—our process generates no wastewater, waste gas, or residue, aligning with sustainable practices and contributing to a cleaner environment.
(4) Versatile adaptability—compatible with a wide range of cements, including Portland, slag, fly ash, and *** ash varieties, as well as various admixtures for maximum flexibility.

Usage Guidelines:

(1) Experimentation is key—recommended dosage ranges from 0.5% to 1.0% by weight of cementitious material. Conduct thorough testing to determine the optimal dosage tailored to the specific characteristics of your cement and aggregates.
(2) Versatile application—our superplasticizer can be seamlessly dissolved in water and integrated with other additives, or directly incorporated into concrete mixtures. For optimal results, we recommend post-compounding addition.
(3) Compatible with various retarders and slump retention agents, our superplasticizer should not be mixed with fatty acids, naphthalene-based, amino-based, or ion-based additives to ensure peak performance.
(4) Our dedicated technical team offers on-site guidance to ensure proper usage and compounding, maximizing your project's success.
