Description
Vasilii Mischinenko, Andrey Vasilchenko, and Georgy Lazorenko made porous building materials in 2024. They used coal gangue and waste concrete powder. Alkali activation turned the wastes into foams. Microwave heating sped up the process. The team varied heating time and power. Their goal was better properties with less energy.
Waste powder content also changed across samples. One mix gave the best overall performance. Strength fell only slightly in that mix. No chemical foaming agent was needed. Microwaves acted directly on the fresh mortar. Energy use dropped as a result. The work supports better waste-based foams. It also supports cleaner production methods.
