Is polycarboxylic acid water reducing agent also widely used?

wallpapers News 2021-05-25
Polycarboxylic acid water reducer is a high-performance water reducer and a cement dispersant in the application of cement concrete. It is widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects. The product is environmentally friendly, non-flammable, non-explosive, and can be safely transported by trains and cars.
Advantages of polycarboxylic acid water reducer
The new generation of polycarboxylate superplasticizer overcomes some of the disadvantages of traditional superplasticizers. It has the advantages of low dosage, good slump retention performance, low concrete shrinkage, strong adjustability in molecular structure, and great potential for high performance. Outstanding advantages such as not using formaldehyde in the process.
1. Good compatibility with various cements, good slump retention performance of concrete, prolonging the construction time of concrete.
2. Low dosage, high water reduction rate and small shrinkage.
3. Significantly improve the early and late strength of concrete.
4. This product has low chloride ion content and low alkali content, which is conducive to the durability of concrete.
5. The production process of this product is pollution-free, does not contain formaldehyde, conforms to the ISO14000 international standard for environmental protection management, and is a green product.
6. Using polycarboxylate water reducer, more slag or fly ash can be used to replace cement, thereby reducing costs

Disadvantages of polycarboxylic acid water reducer
1. Insufficient slump retention under high temperature environment.
2. Strong temperature sensitivity, the same polycarboxylic acid water reducing agent is constructed in different seasons, the concrete slump retention properties are far different.
3. Few functional products, it is difficult to meet the requirements of ultra-high, ultra-long-distance concrete pumping, negative temperature construction, ultra-early-strength concrete preparation, and high durability of concrete.
4. High viscosity. In the high admixture, low water-binder ratio concrete preparation, the concrete viscosity is high, which is not conducive to construction.
5. Strong sensitivity to the mud content of sand and gravel aggregates.
6. The adaptation to machine-made sand is also poor, and the mixing amount is sensitive to affect construction.

How to use polycarboxylic acid water reducer
Under normal circumstances, when the solid content is converted to 20%, the dosage is 0.5 to 1.5% of the weight of the cementitious material, and the recommended dosage is 1.0%. Please consult the supplier for details.
