Abstract
This work is devoted to the consideration of the possibility of creating a material with improved characteristics, namely reduced weight and thermal conductivity, using a filler in the form of hollow ceramic spheres to reduce the stress-strain state of the foundation of soil engineering objects and the effect of temperatures on soil stability. The constituent elements of the geopolymer were studied by electron microscopy methods, their composition and some properties were determined, as well as thermal conductivity, density and compressive strength of geopolymer samples. As a result of the studies, it was shown that adding microspheres to the geopolymer improves its thermal conductivity properties and lightens the design of the roadbed.
