Implication

Randomized trial evaluates rapid hardening properties of alkali-activated mortar with various modifiers, suggesting enhanced performance.

Key Points

The study aims to develop a one-part rapid hardening repair mortar using calcined clay and basic oxygen furnace slag, assessing the impact of different modifiers.
Systematic production of one-part alkali-activated mortar using calcined clay and BOFS.
Comparison of modifiers: sodium fluoride (NF), red mud (RM), calcined alumina (CAL).
Evaluation of compressive strength, drying shrinkage, substrate bond strength according to ASTM and EN standards.
Incorporation of NF reduced setting time by up to 73% and increased 3 h compressive strength to 12.8 MPa (+81% vs. control).
Drying shrinkage decreased from 4252 µƐ to 162 µƐ with the addition of RM, CAL, and NF.
Bond strength improved, meeting R3 and R4 requirements as per EN 1504-3.
