This study investigates the practical application of Modified Fly Ash Slurry (MFAS) as a supplementary cementitious material for concrete. The effects of the stirred storage period on the physical properties of MFAS and the performance of mortar incorporating MFAS were evaluated. The results indicate that stirring MFAS for 91 days reduces its particle size and increases its specific surface area. Stirred storage at concentrations of 60–70wt% had no adverse effect on the compressive strength of mortar, while the best fluidity was achieved at a storage concentration of 65wt%.
