Main varieties of retarding water reducing admixtures

Among the retardant water-reducing admixtures, which are processed from natural products, there are lignin sulfonate series and polyol series. The former is widely used in ordinary water-reducing agents. The polyol system is a retarding water-reducing agent that mainly has a retarding effect and also has a water-reducing and enhancing effect (generally does not entrain air). The main varieties include molasses water-reducing agent, low-density water-reducing agent, etc. Polysaccharide retardant water-reducing agent, sulfamate-based high-efficiency water-reducing agent, polycarboxylic acid-based high-performance water-reducing agent and retarder obtained by compounding naphthyl-based high-efficiency water-reducing agent with retarder or retarding ordinary water-reducing agent. Highly efficient water reducing agent.
