In many concrete projects, traditional high performance concretes such as naphthalene series cannot meet project requirements due to technical performance limitations. A new generation water-reducing agent, high-performance water-reducing agent, polycarboxylate water, which has received much attention at home and abroad because it has developed an effective molecular structure based on a mechanism of cement truly dispersed and super smeared out.
It can prevent concrete from sagging without appreciable delay and prevents concrete from sagging because it can provide higher softening effect at low concentration, good flow retention, high cement content, high molecular weight and high pore removal to be applied to a variety of suitable plastic techniques, good strength development, excellent durability and effective polycyclic acid water reducer.
Arboxylic has comprehensive technical advantages and environmental protection properties that meet the needs of modern concrete technology. Therefore, water-reducing polycarboxylate high-performance water-reducing agents are increasingly used for the production of high-performance concretes. The use of polycarboxylic acid additives is said to account for over 80% of all high performance additive products in Japan and over 50% in North America and Europe.
In my country, polycarboxylate water reducing agents have only been successfully used in the Three Gorges Dam, Sutong Bridge, Tianwan Nuclear Power Plant, Beijing-Shanghai High-speed Railway and other other major national rail and energy systems. Projects that produce meaningful results.
