Viscosity modifiers, also known as rheology-modifying admixtures or workability-retaining admixtures, are concrete additives designed to control the rheological properties of concrete, particularly its viscosity and flow characteristics. Viscosity modifiers are valuable in situations where maintaining the workability and pumpability of concrete is critical. Their use can result in more efficient concrete placement, reduced labour requirements, and improved overall construction quality.
