Alkali-Activated Hybrid Cement from Mineral Wool Fiber Waste and OPC

Cements to replace ordinary portland cement (OPC) are currently being studied due the high environmental costs of OPC production. One viable alternative is alkali-activated cements, which can be made from pozzolanic materials such as stone wool fiber waste (SW). At present, SW most used insulation material in world, and disposal recycling it an challenge its fibrous nature low density. In present work, (AAC) hybrid (AAHC) were obtained alkaline activation SW. The unconfined compressive strength (UCS) AAC AAHC was evaluated. After 28 days curing at room temperature, maximum UCS reached 6.7 MPa for samples without addition 12.3 those with OPC. addition, reaction products identified all combinations through XRD SEM-EDS. results promising they show a industrial product has reduced carbon footprint.
