Foam concrete as ground insulation

Reference number
Funding from Vinnova SEK 100 000
Project duration August 2017 - December 2017
Status Completed

Purpose and goal

To use materials as insulation in the foundation , its properties for this environment must be identified. Tests of, for example, water absorption, water vapor diffusion, drying time etc. are required to predict its function in the construction.

Expected results and effects

Test of water absorption, drying time, capillary rise, water vapor resistance, thermal conductivity and moisture content at different relative humidity, radon transmission have been tested. Pressure strength could not be included as cracking in test bodies was too large.

Planned approach and implementation

For dry designs, the material would function properly. Large capillary rise, high water absorption and relatively long drying time mean that use in free water constructions is doubtful. Special measures for creating capillary-breaking layers may be required. The material has a high transmission for radon and water vapor
