kevytlaastia

Kevytlaastia, translating to "lightweight mortar" in English, is a building material characterized by its reduced density compared to traditional mortars. This lightness is achieved by incorporating air voids or lightweight aggregates into the mix. Common lightweight aggregates include expanded perlite, vermiculite, or hollow spherical particles. The primary benefit of kevytlaastia is its decreased weight, which can lead to structural advantages such as reduced load on foundations and easier handling during construction.

The composition of kevytlaastia typically involves cement, water, and these lightweight aggregates. The specific proportions vary depending on the desired properties, such as thermal insulation, sound absorption, or compressive strength. While lighter, kevytlaastia generally exhibits lower compressive strength than dense mortars. Therefore, its applications are often found in areas where high structural load-bearing capacity is not the primary requirement.

Common uses for kevytlaastia include non-load-bearing interior walls, screeds, thermal insulation layers, and as a bedding material for pipes and utilities. Its insulating properties can contribute to energy efficiency in buildings. Kevytlaastia is also sometimes used in repair work where minimizing added weight is crucial. The application methods are similar to those of conventional mortars, utilizing trowels and other standard masonry tools. Its reduced density also makes it a more sustainable option in some contexts due to lower material transport emissions.
