Polycarboxylate high-performance water-reducing agent is a new generation of environmentally friendly products developed by Qiandao Company and the Cement New Materials Research Institute. Its technical performance reaches internationally leading levels, featuring low dosage, minimal slump loss, and excellent compatibility with various cements and admixtures. It is the preferred choice for preparing high-strength concrete. It has been successfully applied in large-scale high-speed railway construction and major domestic projects, such as the Qinghai-Tibet Railway, the Hangzhou Bay Bridge, the Beijing Olympic Stadium project, the Three Gorges Dam, the Beijing Capital International Airport expansion project, the Sutong Bridge, the Yangshan Deepwater Port Terminal, and the Shanghai Maglev Train tracks.
The water-reducing agent series specifically designed for seawater and sea sand concrete addresses the issues of reduced concrete slump and rapid slump loss associated with seawater and sea sand mixing. It is suitable for concrete construction in coastal, offshore, and deep-sea projects, particularly for plain concrete components such as fence panels, twist blocks, pavement, and airport pavements.
Product Parameters
Powder dosage: 0.16%-0.3% (of cementitious material); water-based additive dosage: 0.8%-2.0% (of cementitious material). The optimal dosage is subject to field testing.
Water reduction rate > 25%; the higher the dosage, the higher the water reduction rate.
It offers excellent early strength and reinforcement, and is compatible with various cements and admixtures.
It has low slump loss and high plasticity, producing high-quality fluidized concrete with excellent pumpability.
It contains no chlorides and poses no corrosion risk to steel bars. Concrete incorporating this product exhibits high resistance to media erosion.
This product can produce high-performance concrete with high strength, high elastic modulus, high impermeability, low shrinkage, and excellent durability.
