“…These precursors contain much less embodied carbon than ordinary Portland cement (OPC), which makes geopolymers the most promising eco-friendly materials. Recently, in practice, geopolymers have been tested for a variety of applications, including membrane and membrane supports [25], acoustic and thermal insulators [26], low-cost ceramics tiles and refractories [27,28], adsorbents and filters [29,30], catalysts [31], pH regulators [32]among others [33].…”

The construction sector is a significant contributor to global greenhouse gas emissions, resource depletion, and environmental degradation. Therefore, sustainable development in the construction sector is essential to reduce its environmental impact. Geopolymer materials have attracted particular attention offering technical properties similar to those of Portland cementitious materials with a much lower CO 2 emission and lower environmental impact. Their use as clean insulating materials seems promising due to their excellent thermal and mechanical properties. Moreover, natural fibers, such as bamboo, flax, hemp, and jute, can be used as reinforcement within the geopolymer matrix, providing additional benefits such as improved tensile and flexural strength, reduced density, and improved thermal and acoustic insulation properties. Hence, this review paper aims to explore the raw materials and manufacturing conditions involved in the formation of compact and porous geopolymer materials. In addition, the various factors affecting the properties of geopolymer materials are critically discussed and compared with those of Portland cementitious materials. Moreover, the impact of many variables, including fiber size, fiber orientation, and fiber content on the performance of natural fiber-reinforced geopolymer composites are highlighted, providing insights for future research developments.
