Popis: | The traditional cement production wastes a large amount of natural resources and energy, and causes environmental pollution, which cannot meet the green and sustainable development needs of modern building materials. Geopolymer is an environmentally friendly materials that can utilize industrial solid wastes and have low environmental load and energy consumption, which is expected to become a substitute for OPC. However, geopolymers also have shortcomings in some properties that need to be improved. This paper reviews the recent research progress on the performance improvement, potential new applicationw and sustainability assessment of geopolymer materials. Discussion from this paper showed that the properties of geopolymer materials, including rheology, hardening properties, toughness, etc., can be significantly improved by some methods such as chemical additives, mineral admixtures, nanoparticles, fibers, etc. Furthermore, this paper proves that geopolymers have great application potential as porous thermal insulation materials and 3D printing building materials, and points out some performance optimization methods for geopolymer-based porous materials and 3D printing materials. In this work, it was also concluded that geopolymer shows significant advantages over OPC in sustainable analysis index such as E-energy and E-CO2 (Energy and CO2 emission) based on LCA method. Finally, a few potential opportunities and development directions have been suggested for future research on geopolymer materials. |
