A new concrete mix sodium nitrate, sodium carbonate, sodium sulfate, calcium chloride, calcium carbide, lime, cement, coarse aggregate and sand in a percent ratio of (0.51-0.70):(0.56-0.58):(0.66-0.90):(0.05-0.10):(0.17-0.40):(0.05-0.01):(25-30):(29.25-12):(30-35) mixed with 13.75 to 20% of water. A process for preparing the composition involves comminution of certain components to a predetermined range of particle size and a treatment to insure certain ranges of moisture content of various components of the composition.
