Kovettuma

Kovettuma is a Finnish noun meaning the process or state of becoming hard or setting into a rigid solid. It derives from the verb kovettaa, “to harden.” The term is used across fields to describe a transition from a malleable, plastic, or liquid state to a solid state through chemical reaction, drying, or thermal treatment. The specifics depend on the material in question.

In construction and civil engineering, kovettuma describes the curing of cement-based materials such as concrete and plaster. During kovettuma, hydration reactions develop strength, and the rate is influenced by temperature, moisture, and insulation. Proper curing improves durability and early strength; common references are to strength development over time and reaching target performance after days of curing, such as seven or 28 days for concrete.

In materials science and engineering, kovettuma also refers to the curing of polymers and resins and to hardening through heat treatment in metals (for example, quenching and tempering) or chemical cross-linking in polymers. The term is also applicable to coatings and composites, indicating the transition to fixed geometry and mechanical properties.

In dentistry and related areas, dental materials undergo kovettuma as they set after mixing or exposure to light or heat, gaining stability and strength.

Overall, kovettuma denotes the general hardening or setting process of a material, with the mechanism, conditions, and measurements varying according to the material involved.
