At present, the use of polycarboxylate superplasticizer in construction is relatively common, because its product performance can enhance the building strength and improve the quality of the project, so it plays a very important role in the construction, the following is to introduce its advantages.
1.The alkali content and chloride ion content are very small, and the addition of polycarboxylic acid mother liquor has no corrosion harm to the reinforcement and no adverse effect on the concrete. At the same time, the product does not salting out and crystallize in low temperature season, which is convenient to use
2.It is beneficial to improve the workability of concrete mixture, reduce bleeding, and improve the appearance quality and durability of hardened concrete. It is especially suitable for fair faced concrete engineering.
3.The concrete prepared with polycarboxylate superplasticizer mother liquor will not have obvious segregation and bleeding even under the condition of high slump, and the concrete appearance color is uniform. When used to prepare high-grade concrete, the concrete has good workability and cohesion, and the concrete is easy to mix.
Therefore, polycarboxylate superplasticizer is very necessary for building construction. It is generally added in proportion when used, which can not only make the project more firm, but also reduce various hazards. Only when we understand the material properties and advantages, we will be able to better apply it in the later stage.
