Powdered polycarboxylic acid water-reducing agent is a new generation of high-performance water-reducing agent appearing at home and abroad in recent years.
Compared with traditional high-efficiency water-reducing agents such as naphthalene series, powdered polycarboxylic acid water-reducing agent has many unique technical performance advantages: (1) low dosage and high water reduction rate; (2) Good fluidity retention; (3) Good compatibility with cement; (4) The shrinkage of the prepared concrete is small, which is helpful to improve the volume stability and durability of concrete; (5) Environmental protection and no pollution during production and use, It is a green admixture. It is precisely because of the above performance advantages that the polycarboxylic acid-based high-performance water-reducing agent has attracted extensive attention in the domestic engineering industry in recent years. Many important projects have already used this new type of water-reducing agent in large quantities, such as Shanghai Maglev, Shanghai World Financial Center, Hangzhou Bay Cross-sea Bridge, Donghai Bridge, Beijing Yintai Building, Beijing Capital International Airport Expansion Project, etc. It is foreseeable that due to the many unique performance advantages mentioned above, powdered polycarboxylic acid water reducer will quickly become the mainstream product in the water reducer market.
Since the polycarboxylic acid water-reducing agent is mostly in a liquid state, the milling process is complicated and the production process is not safe. Therefore, most of them are sold on the market. Due to the improvement of technology and the improvement of the milling process, the polycarboxylic acid water-reducing agent in the powder state has also been more common. In contrast, products in powder form provide a lot of convenience from transportation to customer use. Since then, powder has formed the development trend of such products.
