Mechanical Performance Optimization and Microstructural Mechanism Study of Alkali-Activated Steel Slag–Slag Cementitious Materials

Buildings
The optimal proportion of alkali-activated steel slag–slag cementitious materials is investigated by considering the combined effects of steel slag content, alkali content, water glass modulus, and water–binder ratio using the Box–Behnken design in ...

Components of the Fracture Response of Alkali-Activated Slag Composites with Steel Microfibers

Applied Sciences, 2019
Knowledge of the mechanical and primarily fracture parameters of composites with a brittle matrix is essential for the quantification of their resistance to crack initiation and growth, and also for the specification of material model parameters employed

Impact of activator chemistry on permeability of alkali‐activated slags

Journal of the American Ceramic Society, 2017
Abstract Durability of alkali‐activated slags has been assessed by measuring the permeability using the beam‐bending technique. This nondestructive technique obtains permeability values by measuring the hydrodynamic load relaxation curve of a saturated slender beam of solid paste placed in three‐point bending. The

Alkali activation of fayalite slag

, 2017
In this thesis, alkali activation of fayalite slag was investigated. The slag utilized is a waste by product from nickel production, the activation of which resulted in the formation of a geopolymer binder of acceptable properties. The need for a reduction in overall waste output as well as the cementitious properties exhibited by this slag motivated ...
