alkukosteus

Alkukosteus, a Finnish term, refers to the initial moisture content present in building materials at the time of construction or installation. This moisture can originate from various sources, including the manufacturing process of materials like concrete, timber, and plaster, or from environmental exposure during storage and transportation. It is a crucial factor in construction as it can significantly influence the material's performance and the building's long-term durability.

High alkukosteus can lead to several problems. In timber, it can promote mold growth and wood decay, potentially compromising structural integrity. For concrete and masonry, it can result in efflorescence, a salt deposit on the surface, and can affect the curing process, leading to reduced strength and increased porosity. In newly constructed buildings, excessive alkukosteus is often referred to as "building moisture" and can contribute to poor indoor air quality, potential health issues for occupants, and damage to finishes like paint and wallpaper.

Controlling and managing alkukosteus is therefore an essential aspect of quality construction. This involves proper storage of materials, protecting them from rain and humidity, and ensuring adequate ventilation during and after the construction process. Monitoring alkukosteus levels using specialized equipment helps identify and address potential issues before they become serious problems. Proper management of alkukosteus contributes to a healthier, more durable, and energy-efficient building.
