At present, the use of polycarboxylate superplasticizer water reducing agents is relatively common in construction, because their product performance can improve building strength and engineering quality. This product is green, non flammable, and not explosive, and can be safely transported by train and car. When the dosage of water reducing agent reaches 0.9%~1.1%, the slump of concrete with a water cement ratio of 0.12-0.16 and a sand content of 38% can still be maintained above 250mm for 2 hours, the expansion can reach 600mm, the final setting time is within 24 hours, and there is no segregation phenomenon. The compressive strength at 90 days is even above 180MPa.So it plays a very important role in construction, and the following will introduce its advantages.
1. The alkali content and chloride ion content are very low, and the addition of polycarboxylate superplasticizer mother liquor does not cause corrosion damage to steel bars and has no adverse effects on concrete. At the same time, the product does not salt out or crystallize during low temperature seasons, making it easy to use.
2. It is beneficial for the workability of concrete mixtures, reduces bleeding, improves the appearance quality and durability of hardened concrete, and is particularly suitable for use in plain concrete projects.
3. The concrete prepared with polycarboxylate superplasticizer water reducing agent mother liquor will not exhibit obvious segregation or bleeding even under high slump conditions, and the appearance color of the concrete is uniform. When used to prepare high-grade concrete, the concrete has good workability, good cohesion, and is easy to mix.
So polycarboxylate water reducing agents are very necessary for construction. When used, they are usually added in proportion, which not only makes the project more solid but also reduces various hazards. Only by understanding the material properties and advantages can we apply them well in the later stage. Polycarboxylate superplasticizer water reducing agent is a high-performance water reducing agent and a cement dispersant used in the application of cement concrete. Applied in projects such as highways, bridges, dams, tunnels, and high-rise buildings.
