Key Points

This research aims to evaluate the physical, mechanical, and durability properties of cement mortar using fayalite slag and bottom ash as sand replacements.
Full replacement of standard sand with fayalite slag and bottom ash was assessed.
Partial replacement of standard sand with fayalite slag was also tested for performance.
Mechanical properties were measured according to ASTM standards.
Full replacement of standard sand with fayalite slag yielded comparable properties.
Full replacement with bottom ash negatively affected mechanical properties.
Partial replacement with fayalite slag resulted in the highest mechanical properties and lowest alkali silica reaction rate.

Implication

Study examined the effects of fayalite slag and bottom ash on cement mortar properties, suggesting potential reuse benefits.

Abstract

• Fayalite slag (FS) and bottom ash (BA) can be reused as sand replacement in mortars. • Full replacement of standard sand (SS) with FS resulted in comparable properties. • Full replacement of SS with BA adversely influenced the properties. • Partial replacement of SS with FS resulted in highest mechanical properties. • FS had the lowest alkali silica reaction rate according to ASTM C1260 standard.
