Potassium-Based Geopolymer Composites Reinforced with Chopped Bamboo Fibers
Bamboo is a fast-growing, readily available natural material with tensile specific strength equivalent to that of steel (250–625 MPa/g/cm3). In the pursuit of sustainable construction materials, a composite was made with potassium polysialate siloxo geopolymer as the matrix and randomly oriented cho...
