Sterilization of Biotic Agents by Microwave Technology in Construction Materials

The use of high-frequency electromagnetic microwave radiation in civil engineering is no novelty. There have been various discussions related to this issue. However, they are often based on inaccurate and superficial knowledge. One of the reasons is insufficient access to accurate data with professional description for readers. Since it is a very effective method, it is necessary to realize that every company protects their know-how. Therefore, the aim is to introduce the methods and effectiveness of this microwave (EMW) technology in civil engineering practice. As it is a very effective technology, BUT Brno (Faculty of Civil Engineering) cooperated with a commercial company and performed numerous measurements and experiments that were often close to the conditions occurring at real constructions. Furthermore, BUT Brno, together with the commercial company, performed a large number of measurements in situ conditions related to the sterilization of biotic agents by means of microwave technology. In most cases the measurements were performed at real constructions and focused on drying, moisture elimination, and inactivation of biotic pests.
