The invention discloses high-strength self-compacting concrete and a preparation method thereof, relates to the technical field of concrete, and solves the problem that the whole concrete is cracked due to the fact that sulfate ions easily erode the concrete, and the high-strength self-compacting concrete comprises the following components in parts by weight: 420-460 parts of a cement raw material; 58 to 62 parts of mineral powder; 50 to 60 parts of fly ash; 850 to 860 parts of medium sand; 850-860 parts of a crushed stone raw material; 9-11 parts of a water reducing agent; 140 to 145 parts ofwater; 3-6 parts of magnesium fluosilicate; and 12-18 parts of a filling reinforcing material. The high-strength self-compacting concrete provided by the invention has good and stable sulfate ion corrosion resistance, and is not easy to crack as a whole when being applied to regions with higher sulfate ion content.
