The utilization of glass and fly ash as additives in concrete introduces many benefits from technical and environmental points of view. Change in the compressive strength of concrete depends on the aggregate-cement interactions and interface bonding mechanism. It is well known that silica in the glass can be highly reactive with the alkalis in cement paste. As a result of pozzolonic reaction, fly ash fills in the pores in the material. Therefore, using fly ash and glass as additives in concrete can improve the mechanical properties of concrete.
