The invention provides a cement-based ultra-high strength contraction-free grouting concrete which is composed of cement, quartz sand, water reducer, swelling agent, defoamer, anti-settling agent, steel fiber, retarder and water-retaining agent in parts by weight: 100 parts of cement, 5-10 parts of swelling agent, 50-100 parts of quartz sand, 0.5-2.5 parts of water reducer, 0.3-1.0 part of defoamer, 0.1-0.3 part of anti-settling agent, 5-30 parts of steel fiber, 0-1.0 part of retarder and 0.1-0.3 part of water-retaining agent. The invention has the following beneficial effects: (1) at the normal temperature, the 1d compression strength of the cement-based grouting concrete is improved to be above 70 MPa; (2) at the normal temperature, the 28d compression strength of the cement-based grouting concrete is improved to be above 120 MPa; and (3) the cement-based ultra-high strength contraction-free grouting concrete can be used for installing large, ultra-large equipment basis, and can be used for occasions, such as bolt anchoring, structure fastening, road repair and the like which have high requirements on the compression strength of grouting concrete.
