[0023] Step 1: Take raw materials according to the following parts by mass:

[0024] Cement: 35,

[0025] Medium coarse sand: 9,

[0026] Gravel: 10,

[0027] Blast Furnace Slag: 20,

[0028] Soot: 13,

[0029] Silica fume: 2,

[0030] Steel bar rust inhibitor: 1.5,

[0031] Water reducer: 0.5;

[0032] Step 2: Take out the medium-coarse sand and put it in water to wash away the dirt on the surface, take out the cleaned medium-coarse sand, put it in a cool place for 20 minutes, and dry the water;

[0033] Step 3: Take out all the cement, put it into a mixer for stirring, put in the washed medium-coarse sand and stir for 3 minutes, so that the cement and medium-coarse sand are fully mixed;

[0034] Step 4: Continue to add gravel, blast furnace slag, coal ash and silica fume to the mixer, and stir the mixture evenly;

[0035] Step 5: Continue to add steel rust inhibitor to the mixer, and add a small amount of water to make the concrete mix evenly, and stir until it becomes

[0041] Medium coarse sand: 15,

[0042] Gravel: 11,

[0043] Blast Furnace Slag: 26,

[0044] Soot: 19,

[0045] Silica fume: 5,

[0046] Steel bar rust inhibitor: 3,

[0047] Water reducer: 2;

[0048] Step 2: Take out the medium-coarse sand and put it in water to wash away the dirt on the surface, take out the cleaned medium-coarse sand, put it in a cool place for 20 minutes, and dry the water;

[0049] Step 3: Take out all the cement, put it into a mixer for stirring, put in the washed medium-coarse sand and stir for 3 minutes, so that the cement and medium-coarse sand are fully mixed;

[0050] Step 4: Continue to add gravel, blast furnace slag, coal ash and silica fume to the mixer, and stir the mixture evenly;

[0051] Step 5: Continue to add steel rust inhibitor to the mixer, and add a small amount of water to make the concrete mix evenly, and stir until it becomes gel
