Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a quantitative addition device for polycarboxylate superplasticizer in concrete. Background Technology
[0002] With the advancement of modern construction technology, the performance requirements for concrete are becoming increasingly stringent. Concrete not only needs high strength and good durability, but also excellent workability and construction efficiency. Polycarboxylate superplasticizers, as high-performance concrete admixtures, can significantly improve concrete fluidity, reduce water consumption, and enhance durability. Therefore, they are widely used in the concrete industry. During concrete production, the amount of superplasticizer added has a significant impact on concrete performance. Traditional methods of adding superplasticizers often rely on manual operation, making it difficult to ensure the accuracy of the dosage and easily leading to unstable concrete performance.
[0003] In practical use, the single-angle mixing of the mixing rod cannot fully cover all corners of the mixing tank. During the mixing process, particles and paste in the concrete may settle due to uneven mixing force, resulting in insufficient mixing in some areas. This uneven mixing leads to a decrease in the homogeneity of the concrete and affects its final performance. Utility Model Content
[0004] The purpose of this invention is to provide a quantitative addition device for polycarboxylate superplasticizer in concrete. Through the design of the stirring rod and the cooperation of the arc block, the mixing is more efficient. The arc block helps the stirring blades to form a better mixing trajectory in the tank, reducing the dead corners of the mixing. Since the superplasticizer can be evenly distributed, the fluidity, strength and durability of the concrete are improved, thereby improving the overall quality of the building.
