At present, polycarboxylate water reducer is still widely used in building construction. This is because its product performance can improve building strength and engineering quality. It is environmentally friendly, non-flammable and non-explosive, and can be safely transported by train and automobile.
At present, polycarboxylate water reducer is still widely used in building construction. This is because its product performance can improve building strength and engineering quality. It is environmentally friendly, non-flammable and non-explosive, and can be safely transported by train and automobile.Therefore, it plays a very important role in building construction, and its advantages will be introduced below.
1. The content of alkali and chloride ion is very small. After adding the polycarboxylic acid mother liquor, there is no harm to steel corrosion and no bad effect to concrete.At the same time, the product is not salting out in the low temperature season, no crystallization, easy to use.
2. It is conducive to improving the workability of concrete mixture, reducing bleeding and improving the appearance quality and durability of hardened concrete, especially suitable for use in fair-faced concrete projects.
3. The concrete prepared with polycarboxylic acid water reducer mother liquor will not have obvious segregation and bleeding even under the condition of high slump, and the concrete appearance is uniform in color.When used to prepare high-grade concrete, the concrete has good workability, good cohesion and is easy to mix.
Therefore, polycarboxylate water reducer is very necessary for building construction, and it is generally added in proportion when it is used, which can not only make the project more solid but also reduce various hazards. As long as we understand the material properties and advantages, we will be able to better apply it in the later stage.Polycarboxylic acid water reducer is a kind of high performance water reducer and a kind of cement dispersant in the application of cement concrete.It is widely used in highway, bridge, dam, tunnel, high-rise building and other projects.
