The research into alternatives for replacing cement in concrete has increased in recent years to reduce environmental impact. Geopolymers or alkali-activated materials are one of the options. This project aims to develop a wet cell based on a geopolymer with alginate and natural fibers.
The wet cell will be a final prototype consisting of panels for wet construction areas such as bathrooms and kitchens. Currently, there is a lack of bio-based solutions for wet spaces on the market. This project, in collaboration with suppliers and users from the industry, aims to provide a solution for a wet cell using bio-based materials. The natural fibers added to the geopolymer will partially replace sand and gravel, resulting in a lighter product than concrete. Additionally, the fibers enhance thermal and acoustic insulation. Natural fibers must be pretreated to improve their bonding with other materials in the mixture. The chemicals used in alkali-activated materials are the same as those used for fiber pretreatment. Moreover, alginates extracted from seaweed can be used as binders, and alkali is used in the extraction process.
Objectives
One of the objectives is to develop the method and technique for producing geopolymers with alginates while simultaneously pretreating the fiber during mixing. After defining the optimal geopolymer mixture, panels will be produced, and ultimately, a wet cell will be constructed using the geopolymer panels.
