The invention relates to a slab joint shoving material for an ALC external wallboard and a preparation method thereof. The slab joint shoving material is prepared from, by weight, 30-97% of a cementing agent, 1-10 parts of a self-repairing master batch, 1-5 parts of a volume stabilizer, 0-1 part of a defoaming agent, 0-60 parts of filler, 1-10 parts of emulsified paraffin, 0.1-2 parts of a water retaining agent, 0.1-1 part of a thixotropic agent and 0-1 part of a condensing time regulating agent. The slab joint shoving material has the good bonding strength, tensile breaking strength and breaking elongation at break and has the low volume change rate, water absorbing rate and water absorbing speed; meanwhile, the slab joint shoving material further has the certain micro-crack self-repairing, sealing performance and flexibility, and ensures the engineering quality of an autoclaved aerated concrete external wallboard.
