dc.description.abstract | In the terms of cost reduction, design flexibility, time and environmentally friendly process, additive manufacturing is gaining acceptance as an innovative technology in the construction industry. The energy demand estimation, as one of the primary parts of building industry nowadays, imposed a need for constant development of the existing materials. Taking into consideration stresses in the material and thermal transmittance value, several mixes that have adequate consistency and workability are described. The common is concrete base consisting of cement, sand and additives. Other elements include geopolymers, fibers, soil, clay, gravel, sulfur. Considering standards and regulations for the maximum thermal transmittance value (U-value), in the countries of Eastern Europe specifically, all considered mixes had greater U-value. The various wall configuration with different cavities inside (empty or filled with sand) enables better thermal properties of the wall that can obtain U-value less than legislation prescribes. | sr |
