Architectural Flooring Systems
The expansive cement additive, marketed as Komponent, is an ettringite-based system that is used with all types of portland cements (ASTM C150) and blended hydraulic cements (ASTM C595) like Types 1L, 1S, 1T, 1C, 1P and LC3.
The early ettringite formation produces designed expansion within the concrete or grout mix that effectively counteracts tensile stress, overcomes drying shrinkage, and prevents negative volume change. The amount of expansion is engineered into the concrete mix to compensate for the shrinkage characteristics of the local cement source, SCMs, and any other constituents that influence shrinkage of the concrete.
Shrinkage-compensating concrete is placed with some form of restraint, whether traditional rebar, post-tensioning tendons, steel fibers, micro-rebar, or synthetic fibers. The initial designed expansion puts the reinforcement into tension and the concrete into compression.
In conventional concrete slabs, drying shrinkage cracks occur when movement caused by drying shrinkage is resisted by an external restraint, such as friction with the subgrade. This produces tensile stress that literally "tears" or fractures the concrete. By preventing negative volume change, shrinkage-compensating concrete and grouts effectively prevent drying shrinkage cracking that leads to early deterioration, maintenance and repairs.
No. Shrinkage-reducing admixtures (SRAs) are designed to delay shrinkage by influencing the surface tension of excess pour water. This decreases capillary stress and shrinkage induced during drying. Over time, these effects diminish and the excess free water is released, resulting in delayed drying shrinkage.
Komponent technology creates a high-quality cement paste that efficiently consumes mix water during hydration and chemically binds the water molecules within the ettringite structures. Once chemically bound, they cannot be separated, ensuring dimensional stability of the concrete.

For over 60 years, Komponent (Type K) shrinkage-compensating concrete has been meeting stringent sustainable design requirements. By improving durability, optimizing low GWP mix designs, and reducing total volume of concrete and reinforcement required, carbon intensity (GWP) savings and cost savings are optimized. Learn how Komponent ShCC helps maximize sustainable design without sacrificing performance. Learn how.
Shrinkage-compensating concrete is a high-performance concrete solution that delivers exceptional results. Historically, an ShCC solution has come at a premium largely due to limitations in design methodologies that resulted in overdesign. Today's advanced finite element analysis (FEA) tools overcome the limitations of the past and now efficiently and effectively optimize designs without unnecessary overdesign. Overdesign drives costs in numerous ways: financially, construction schedules impacts, and in carbon intensity impacts. Design comparisons are available that allow Owners and Engineers to effectively evaluate design options "side-by-side" that provide valuable insight into construction costs, schedule impacts, carbon savings and ultimate return on investment (ROI).
