Admixtures

Plasticizers

Description

Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.

Transcript

Consider concreting in locations that are difficult to access in a mold. Plasticizers help concrete compact on its own, enhancing workability with less water or cement.

Common plasticizers include lignosulfonic acids and hydroxylated carboxylic acids, functioning as water-reducing admixtures that can cut water use by 5 to 15 percent in co...
