    Abstract: Geopolymers have recently emerged as a promising class of inorganic aluminosilicate polymer materials. They present a viable alternative to Portland cement, which is well known for its significant contribution to greenhouse gas emissions. To support the reduction of these emissions, this study aims to develop geopolymer cements by investigating the... Show More
