Development of Alkali-Activated Binders from Recycling Regional Tuff and Marble Wastes

The sustainability goals of the developing world have led many industries to recycle their wastes and reduce emitting greenhouse gases. To contribute these environmental responsibilities, this study has focused on development eco-friendly binder materials from regional ground tuff marble by activation Na2SiO3 NaOH or slaked lime (Ca(OH)2). results show that alkali-activated composites tend expansion, drying shrinkage cracking, leaching efflorescence. compressive strength values Ca(OH)2-activated pastes reached up 15 MPa 9 MPa, respectively. A reduction in molarity improved strength, dimensional stability durability tuff-based pastes.
