- Abstract
The paper presents experimental results obtained in the manufacturing process of a glass foam obtained from the recycling of glass from cathode ray tubes (CRT). The glass foam samples were performed experimentally by the sintering-foaming process. The heating technique was unconventional, the energy provided by the microwave was used as a heat source. The process is different from the conventional techniques applied both in the manufacture of industrial glass foam and in the numerous small-scale experiments known in the literature. The glass foam samples obtained were characterized by traditional methods of analysis. The main characteristics were bulk density, porosity, thermal conductivity, compressive strength, water absorption and microstructural configuration of the samples. The experimental results proved that the applied process obtained a glass foam with good characteristics (porosity of 90%, thermal conductivity of 0.042 W / m-1 • K-1 and compressive strength of 2.1 MPa) usable in construction.
