The invention discloses a magnesite concrete which is prepared from the following raw materials in parts by weight: 50-60 parts of magnesite, 320-400 parts of ordinary Portland cement, 6-10 parts of bentonite, 10-20 parts of coal gangue, 5-8 parts of novel water reducing agent, 3-5 parts of rosin, 500-600 parts of river sand, 3-4 parts of magnesium chloride, 30-50 parts of blast-furnace cinder, 5-10 parts of dry carbide slag, 1-2 parts of sodium lauroyl sarcosine, 3-5 parts of bone coal, 170-200 parts of water, 3-5 parts of glass powder, 1-2 parts of ferrous sulfate, 4-6 parts of calcium phosphate, 1000-1100 parts of limestone rubble, 1-1.6 parts of air entraining agent and 1-2 parts of ethylenediamine tetraacetic acid. After the magnesite is mixed in the magnesium chloride solution and mixed with the solution a, the hardness and surface water resistance are effectively enhanced. The concrete has the advantages of high overall quality, high wear resistance, high impact resistance, high hardness, favorable crack resistance, long service life, high safety and environment friendliness.
