▎ 摘  要

NOVELTY - Concrete comprises 420-460 pts. wt. cement-based raw materials, 720-760 pts. wt. sand, 1000-1200 pts. wt. quartz sand, 30-45 pts. wt. additive, 0.8-1.6 pts. wt.antibacterial agent, 7-10 pts. wt. dispersant, and 150-160 pts. wt. water. USE - Antibacterial and corrosion resistant concrete for deep drainage. ADVANTAGE - The antibacterial and corrosion resistant concrete has good anti-microbial erosion performance, at the same time, it can resist the harm caused by dry-wet and bad alternation, it is used for urban underground deep pollution discharge tunnel with higher service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing antibacterial and corrosion resistant concrete for deep drainage, which involves: 1. placing cement-based raw material admixture, quartz sand, quartz mixing uniformly to obtain dry mixed material, dispersing agent, antibacterial agent; 2. dispersing additive is in water to obtain mixed solution; 3. adding the mixed solution in the dry mixing, stirring and mixing uniformly to obtain the antibacterial and corrosion resistant concrete.
