Product Description

Presenting the BT-302 Polycarboxylate Superplasticizer (Slump Retaining) solid content of 50% in liquid form.

Introducing the BT-302 Polycarboxylate Superplasticizer, a cutting-edge slump-retaining agent crafted with a novel mother liquor, meticulously developed by Shandong Gaoqiang New Material Technology Co., Ltd. This innovative superplasticizer is enhanced with imported additives and boasts an advanced synthesis process in collaboration with leading polyether manufacturers. The result is a revolutionary catalyst and control system, underscored by a scientifically engineered molecular structure.

To address diverse customer demands, Gaoqiang has ingeniously engineered a modern polycarboxylate-based superplasticizer that excels in retaining slump while offering impressive dispersibility. This innovation draws upon the principles of slump loss in freshly mixed concrete, leveraging post-addition methods of superplasticizers and groundbreaking research on reactive polymers. By altering the adsorption behavior of admixtures and meticulously designing the polymer's architecture, this product mirrors graft copolymer admixtures but stands out with its elongated graft side chains, reduced carboxyl group ratios, and strategically placed ester cross-linking points.

The elongated polyethylene glycol side chains within the copolymer molecules offer notable steric hindrance effects, effectively decelerating the cement particles' physical aggregation. A modest polymer amount at the cement-water interface enhances dispersibility. As the ester cross-linking points hydrolyze in the alkaline cement medium, they gradually release low molecular weight copolymers, enhancing dispersing functionality within the cement-water system. This action compensates for the superplasticizer consumption due to C3A and C4AF, maintaining its critical micelle state and effectively averting significant slump loss.

Performance Characteristics Elegantly Outlined:

(1) Remarkably, there is no slump loss after 1 hour, with over 80% of the initial slump retained after 2 hours. This effectively resolves rapid slump loss challenges in concrete, meeting specialized slump retention requirements seamlessly.
(2) The concrete showcases excellent workability, characterized by high fluidity and ease of pouring and compacting. This feature significantly reduces concrete viscosity, making it ideal for pumping applications.
(3) Environmentally conscious, this product's production process generates no waste water, gas, or residue, aligning with eco-friendly practices.
(4) Demonstrating wide compatibility, it adapts seamlessly to a variety of cements, including Portland, ordinary Portland, slag Portland, fly ash, *** ash, and diverse admixtures.

Comprehensive Usage Guidelines:

(1) For optimal results, a recommended experimental dosage ranges from 0.5% to 1.0% by weight of the cementitious material. Testing is advised to determine the optimal dosage based on the specific characteristics of the cement, aggregates, and other materials.
(2) This superplasticizer can be seamlessly dissolved in water and compounded with other additives, or directly incorporated into concrete mixes. For optimal results, it's recommended to add it post-compounding.
(3) It can be synergistically used with various retarders and slump retention agents. However, it's advisable to avoid mixing it with fatty acids, naphthalene-based, amino-based, or ion-based additives to maintain peak performance.
(4) Our expert technical team is available to provide on-site guidance for proper usage and compounding, ensuring optimal performance.
