Anti-freezing concrete and preparation method thereof
The invention discloses anti-freezing concrete and a preparation method thereof. The anti-freezing concrete is prepared from the following raw materials in parts by weight: 300-400 parts of cement; 70 to 80 parts of fly ash; 600 to 700 parts of sand; 1000 to 1100 parts of stone; 5 to 10 parts of a water reducing agent; 130 to 150 parts of water; 1.5 to 2.5 parts of an air entraining agent; 50 to 80 parts of modified basalt fiber; 20 to 30 parts of polyacrylonitrile fiber; 10 to 20 parts of hydroxyethyl cellulose; the modified basalt fiber is prepared by modifying basalt fiber, ethanol, nitric acid, polyacrylate and hydrazine hydrate. The concrete has the effect of improving the freeze-thaw resistance of the concrete.
