Effects of Nano Silica and Basalt Fibers on Fly Ash Based Geopolymer Concrete
Emission of carbon dioxide gas has been a source of major concern for the construction industry. To curb this emission, geopolymer concrete has been deemed as a potential alternative in the recent studies. Previous research also indicates that silica and fibers provide strength benefits to ordinary...
