Corrosion-resistant concrete for saline-alkali soil environment
The invention relates to corrosion-resistant concrete for a saline-alkali soil environment. The corrosion-resistant concrete is characterized by comprising the following raw materials in parts by weight: 240-300 parts of ordinary Portland cement, 172-216 parts of water, 36-48 parts of fly ash, 36-48 parts of slag powder, 7-9 parts of an expanding agent, 288-360 parts of medium sand, 192-240 parts of fine sand, 720-900 parts of stones, 7-9 parts of an anti-permeability agent, 4-6 parts of a water reducing agent, 4-6 parts of an SRA preservative and 4-6 parts of polypropylene fibers. The invention further provides a preparation method of the corrosion-resistant concrete for the saline-alkali soil environment.
