Is water reducing agent the most ideal water reducing agent? It seems so

As one of the raw materials of concrete, admixtures play an important role in infrastructure construction. In particular, water reducing agents have excellent comprehensive properties, are green and environmentally friendly, and have a wide control range. Water reducing agents use a variety of polymer compounds as the main raw materials. Due to different processes, the raw materials are also different. Low dosage can reduce water by 20% to 40%, the slump is basically not lost within 60 to 120 minutes, there is no bleeding and segregation phenomenon, and the alkali content is low, which is beneficial to inhibit the alkali aggregate reaction of concrete.

Water-reducing agent with the highest scientific and technological content

It is a high-performance water-reducing agent with good cohesion and pouring performance. The dosage is significantly lower than other types of water-reducing agents, and the water-reducing rate is higher than that of naphthalene-based water-reducing agents. It is suitable for the configuration of medium and high-strength high-performance concrete. The fluidity of concrete formulated with water-reducing agents is better than that of naphthalene-based water-reducing agents. Better fluidity can be obtained by adding dosage in each age, with small slump loss and no bleeding. More suitable for transporting pumped concrete over long distances. It has good fluidity and is easy to vibrate and compact. After the concrete is hardened, the appearance is dense and smooth, with few large pores and uniform distribution of small bubbles, which is beneficial to improving the frost resistance and impermeability of the concrete, and has the characteristics of early strength and high strength. It can be used in conjunction with fly ash mineral powder to reduce cement consumption.

Water-reducing admixtures are easier to disperse in concrete than naphthalene-based water-reducing admixtures. They are easy to vibrate and maintain plastic during construction. They technically solve the problems of poor fluidity and slump retention with traditional admixtures. Difficult question.

The application cost of high-performance water-reducing agents is generally lower than that of naphthalene-based water-reducing agents. Especially for high-strength grade concrete, the amount of water-reducing agents used is less, which can reduce the total cost.

The high-performance water-reducing agent is the third generation of high-performance water-reducing agent developed after the ordinary water-reducing agent represented by lignocalcium and the high-efficiency water-reducing agent represented by naphthalene series. The powder is A powdery high-performance water-reducing agent made through a spray drying process. It has excellent comprehensive indicators, is green and pollution-free, and is a high-performance and environmentally friendly product.

It has good dispersion, high water reduction rate and good adaptability to various cements. It is suitable for cement sculpture craft components, dry powder mortar, tile adhesive, caulking agent, gypsum products, and colored wear-resistant concrete floors. The early strength and impermeability of concrete are significantly increased, and the construction performance and water retention are better, and it will not be alkaline. This product complies with the GB national standard for high-performance water-reducing agents.

A new type of high-tech water-reducing agent synthesized using international advanced technology. It has a higher water-reducing rate and strength growth rate and does not crystallize in winter. Contains no chlorine salt and has no rust on steel bars. With high water reduction rate and low air entrainment, it is especially suitable for preparing high-strength and large-slump commercial concrete. The high-strength concrete prepared by it has particularly good workability, very little bleeding, and small slump loss

Low dosage, high water reduction rate and small shrinkage.

Significantly improve the early and late strength of concrete.

This product has low chloride ion content and low alkali content, which is beneficial to the durability of concrete.

This product has a pollution-free production process, does not contain formaldehyde, and complies with the ISO14000 international environmental protection management standard. It is a green and environmentally friendly product.

Application scope of water reducing agent

Suitable for precast and cast-in-place concrete in the construction of high-speed railways, passenger dedicated lines, industrial and civil buildings, roads, bridges, ports, airports and other projects , reinforced concrete and prestressed concrete.

Especially suitable for projects with long construction time of prepared concrete and high requirements for maintaining concrete slump, such as nuclear power projects.

Water reducing agents have been used in key national water conservancy projects, nuclear power plants, high-speed railways, cross-sea bridges, undersea tunnels, etc. Performance proves strength, facts are better than advertisements. </p
