  • Patent number: 5728208
    Abstract: 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):(2 5-30):(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.

  • Patent number: 5728428
    Abstract: A new composition for the protection of a body of concrete sodium nitrate, sodium carbonate, sodium sulfate, calcium chloride, calcium carbide, lime, cement, and sand in a percent ratio of (0.9-1.8):(2-3):(2.5-3.6):(0.05-0.15):(0.75-1.15):(0-8-1):(36-40):(49-39.3 ) mixed with 8 to 10% 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. A new method for the application of the protective composition involves the preparation of the surface being protected to increase the exposed surface area of the surface being protected by a factor of 1.15 to 1.36.
