The present invention discloses flexible concrete for seam sealing, wherein the flexible concrete comprises, by mass, 15-25% of an inorganic cementing material, 1.0-2.0% of an expansion material, 4-8% of a filler, 40-60% of stone, 15-30% of sand, 0.3-1.0% of high strength special fibers, 3-6% of a macromolecule additive, and the balance of water. According to the present invention, the price of the selected raw materials is low, the bonding requirements with the old base surface can be met, and the good water resistance can be provided; and the flexibility and the expansion property of the concrete are improved so as to effectively reduce the pavement load and the harm caused by vibration.
