Sika develops and markets a complete range of admixtures and additives for use in concrete, cement, and mortar production. These products enhance specific properties of the fresh or hardened concrete, such as workability, watertightness, durability, load-bearing capacity, or early and final strength. The demand for admixtures and additives is currently on the rise, particularly due to the increased performance requirements placed on concrete and mortar, especially in urban areas and for infrastructure construction. Furthermore, the growing use of alternative cementitious materials in cement, mortar, and therefore also in concrete, is increasing the need for admixtures.

Innovations

Extended workability, controlled over several hours, is especially important for urban construction sites with congested traffic, or remote areas resulting in long transportation times. At the same time, once the concrete is placed, fast curing is of utmost importance to meet tight construction schedules. Sika ViscoFlow® is a workability enhancing admixture, based on a new inhouse-developed polymer which significantly prolongs the workability time of the fresh concrete and still ensures equally fast strength development. The workability time can be modified in accordance to jobsites requirements.
