What is a water reducing agent


Water reducing agent is a surface active agent, and its molecular formula consists of two parts: hydrophilic and hydrophobic groups. When cement is mixed with Water, there is no Water saving technology. Due to the role of molecular cohesion between cement particles, the glue will form a coagulation structure, as shown in Figure a below. A part of the river water will be wrapped in the flocculation structure of the cement particles, thereby reducing the fluidity of the concrete mixture. After falling into the cement slurry, water reducing agent will be added, The Water mixing group of the water-reducing agent is directionally adsorbed on the cement, and the surface cement particles carry the same electric charge on the surface, causing the cement particles to separate, as shown in Figure b below, thereby releasing the Uri water in the flocculation structure. The water-reducing agent's adsorption, dispersion, wetting, and lubrication effects make the concrete mixture increase its fluidity without increasing water consumption. In addition, Water reducing agent can also form a layer of a solvated water mill on the surface of cement particles, which plays a good lubrication role between cement particles. It can increase liquidity. Increase the fluidity of the concrete mixture when the original mix ratio remains unchanged; that is, the water-cement balance and strength remain unchanged. Increase strength. Under the condition of maintaining fluidity and cement consumption, mixing Water can be reduced, decreasing the water-cement ratio, thereby improving the strength of concrete. Save cement. Under the condition of maintaining constant stability, i.e., constant water-cement balance and constant fluidity, it is possible to reduce mixing Water, thereby reducing the amount of cement used, ensuring strength and saving cement. Improve other properties. Adding Water reducing agents can also improve the cohesiveness and water retention of concrete mixtures, Improve the compactness and durability of hardened concrete, and Reduce and delay the hydration heat of concrete.
