High Performance Concrete Water Reducer

Polycarboxylic acid concrete water reducer agent is an effective water reducing agent and cement dispersant in cement concrete applications. It is widely used on roads, bridges, embankments, tunnels, skyscrapers and other projects.

The water reducing agent is environmentally friendly, non-flammable, explosive and can be safely transported in trains and cars.

Based on the differences in backbone structures, polycarboxylic acid superplasticizer products can be divided into two categories: the use of acrylic acid or methacrylic acid as backbone types and the grafting of polyethers with different lengths of side chain.

Others are polyethers whose primary bond is maleic anhydride and have different side chain lengths. Based on this, several high performance water reducing products with different properties have been derived.

Prior to the formation of the polycarboxylate dehydrating agent, it was necessary to reconstitute the supernatants from the polycarboxylate supernatants. It has the advantage of low dosage, good droplet stability, low concrete shrinkage, high controllability of molecular structure and high potential for high performance. Significant advantages such as the absence of formaldehyde in the process.

For the synthesis of a water reducing agent of a polycarboxylate, the design of the molecular structure is crucial, including the backbone group, the side chain density, and the side chain length in the molecule. The synthesis processes mainly comprise a grafting process with in situ polymerization, first a polymerization process, then a functionalization process and a direct copolymerization process of the monomers.

In many concrete projects, traditional high performance concretes, such as the naphthalene series, are unable to meet project needs due to technical performance limitations. A new generation water reducing agent, high performance water reducing agent, polycarboxylate water, which has attracted much attention at home and abroad because it designed effective molecular structure based on mechanism of truly dispersed and superdispersed cement.

It can prevent concrete from sagging without noticeable delay and prevent concrete from sagging because it can provide higher softening effect at low concentration, good flow retention, high cement freedom, molecular weight by weight and high pore removal to accommodate a variety of synthetic techniques. , good strength development, excellent durability and effective polycyclic acid water reducer.

Arboxylic has comprehensive technical advantages and environmental protection characteristics that meet the needs of modern concrete technology. Therefore, water-reducing polycarboxylate high-performance water-reducing agents are increasingly becoming the choice for the production of high-performance concretes.

According to reports, the use of polycarboxylic acid additives accounted 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 others important national water protection systems, bridges, nuclear energy and railways. projects that produce meaningful results.
