Mechanical and protective properties of cement mortar modified with nanomagnetite under high temperature conditions

Key Points

• Investigate how nanomagnetite modifies the mechanical and protective properties of cement mortar under high temperatures.
• Cement mortar samples modified with varying concentrations of nanomagnetite were tested.
• Mechanical and protective properties were evaluated under high temperature conditions.
• Comparative analyses against standard cement mortar were conducted.
• Nanomagnetite significantly improved the compressive strength of cement mortar under high temperatures.
• Protective properties against thermal degradation were enhanced, showing a 30% improvement in durability.
• The optimal concentration of nanomagnetite was found to enhance performance without compromising workability.
