Geopolymers have emerged as a promising green technology in the construction industry. With their lower energy requirements and ability to reduce carbon footprints, they offer a sustainable alternative to traditional construction materials. One particular area of research that has gained significant attention is the use of Sidoarjo mud as an amorphous alumina-silicate material in geopolymers. Previous studies have highlighted the potential of Sidoarjo mud in geopolymers. However, it has been found that the high chloride content in the mud can negatively impact the durability of the geopolymer. This issue has become a major concern for researchers worldwide, as it affects the long-term performance and stability of geopolymer-based structures. To address this challenge, researchers are exploring various strategies to mitigate the impact of high chloride content in Sidoarjo mud. One approach is to modify the composition of the mud by reducing the chloride content through washing or leaching processes. Another approach is to incorporate additives or admixtures that can effectively bind the chloride ions and prevent their migration within the geopolymer matrix. In addition to the chloride issue, the physical and chemical stability of geopolymers is another key area of research. Geopolymers have shown good resistance to chemical attack, making them suitable for harsh environments. Their porous structure also allows for ion exchange, which can further enhance their performance in concrete applications. The use of geopolymers in construction offers several advantages over traditional materials. Not only do they have lower energy requirements, but they also have the potential to reduce carbon emissions. Geopolymers can be produced using industrial by-products or waste materials, further contributing to sustainable practices in the construction industry. In conclusion, the use of geopolymers as a green technology in construction holds great promise. While challenges such as the high chloride content in Sidoarjo mud need to be addressed, ongoing research and development efforts are focused on finding solutions. With their good physical and chemical stability, as well as their potential for ion exchange, geopolymers have the potential to revolutionize the construction industry and contribute to a more sustainable future.
