Determination method for compressive strength of tailing cemented filling body

The invention discloses a method for measuring the compressive strength of a tailing cemented filling body, and belongs to the technical field of mine filling strength measurement, and the method comprises the following steps: step 1, coating a layer of engine oil on the inner surface of a test mold, and placing a piece of thin paper at a bottom air pump hole; 2, according to the mine filling concentration and the lime-sand ratio requirement, materials needed by the test are weighed; 3, stirring the mixed slurry sample for 2-3 minutes, filling the test mold with the slurry sample at one time, and standing for 24-28 hours to form a pre-test piece; 4, during the standing maintenance period of the test piece, absorbing water secreted from the surface of the slurry every one hour; 5, demolding the filling test piece; step 6, putting the demolded test piece into a curing box for curing; 7, the test piece is placed in a mortar compression resistance clamp to be subjected to compression resistance detection; the inv
