What Are Water Reducing Admixtures


Water Reducing Admixtures are mainly used in areas that experience hot and humid weather for concrete pumping, tremie, and placing. Careful concrete placement becomes required since the "initial" time to set will typically occur 1 hour earlier. It has also been shown that WRA use increases the concrete's initial compressive strength (up to 28 hours) by 10% when compared to a control mixture. Another benefit relating to the use of WRA is that the higher density of the concrete is achieved, making the concrete a lot less porous while obtaining higher durability and improving the overall quality of the mixture. A water-reducing admixture can reduce the water consumption for concrete mixing while keeping the concrete slump unchanged. Most are anionic surfactants, such as lignosulfonate, naphthalenesulfonate formaldehyde polymer, etc. After adding the water-reducing admixtures to concrete, it can disperse the cement particles, thereby improving its workability, reducing the unit water consumption, improving the fluidity of the concrete mixture, or reducing the unit cement consumption and saving cement. And achieve the goal of reducing cement costs for investors. Water-reducing admixtures can be categorized into liquid and powder types according to their appearance. The solid content of liquid agents is generally 20% and 40% (also known as mother liquor). According to the water-reducing and reinforcing capacity of the water-reducing agents, they can be categorized into standard type,  pumping type, slump-preserving type, regarding the type, and antifreeze type.
