Abstract
In the world, inert materials are used to obtain high-strength concrete, the volume weight of which is quite large. We cannot get concrete with low thermal conductivity from such inert materials. Therefore, in order to obtain high-strength, environmentally friendly and energy-efficient concrete, it was necessary to investigate local inert materials. The subject of research is natural zeolite and recycled ceramic waste, as well as polystyrene as an additive and micro-silica in cement mass to achieve penetrating waterproofing. The mentioned materials are obtained in Georgia in sufficient quantity, which allows us to produce energy-efficient concrete of high strength, low thermal conductivity, as well as sound and waterproofing. It is safe for both people and the environment. The correct mix will be provided by materials found in the local market, and the desired and low energy efficiency ensures the production of an environmentally friendly concrete.
