NOVELTY - A concrete drainage pipe comprises 150-160 pts. wt. regenerated aggregate, 8-10 pts. wt. fine coal gangue, 45-55 pts. wt. fly ash, 1.6-2.2 pts. wt. lime, 0.6-0.9 pt. wt. gypsum, 0.05-0.08 pt. wt. aluminum powder, 1.5-1.8 pt. wt. diatomaceous earth, 37-40 pts. wt. cement, 1-1.5 pt. wt. nano-silica, 0.5-1 pt. wt. graphene oxide, 2-2.5 pts. wt. redispersible latex powder, 30-40 pts. wt. fine sand, 50-80 pts. wt. crushed stone, 0.035-0.055 pt. wt. plasticizer, 0.09-0.1 pt. wt. water-reducing agent and 100-140 pts. wt. water. The fineness of fly ash is 5-15% after passing through 45 microm square-hole sieve. The fineness of fine sand is 10-20% after passing through 80 microm square-hole sieve. The fineness of regenerated fine aggregate is 10-30% after passing through 0.15 mm square-hole sieve. The fineness of aluminum powder is 0.5-1% after passing through 80 microm square-hole sieve. The cement is Portland cement. USE - Concrete drainage pipe. ADVANTAGE - The lime fly ash regenerated aggregate permeable concrete product has high compressive strength, good water permeability, good anti-freezing performance, strong adaptability to the environment, and has excellent ecological environment benefit, and ensures the stability of the mixed material preparation drain pipe, reaching the strength requirement. DETAILED DESCRIPTION - A concrete drainage pipe comprises 150-160 pts. wt. regenerated aggregate, 8-10 pts. wt. fine coal gangue, 45-55 pts. wt. fly ash, 1.6-2.2 pts. wt. lime, 0.6-0.9 pt. wt. gypsum, 0.05-0.08 pt. wt. aluminum powder, 1.5-1.8 pt. wt. diatomaceous earth, 37-40 pts. wt. cement, 1-1.5 pt. wt. nano-silica, 0.5-1 pt. wt. graphene oxide, 2-2.5 pts. wt. redispersible latex powder, 30-40 pts. wt. fine sand, 50-80 pts. wt. crushed stone, 0.035-0.055 pt. wt. plasticizer, 0.09-0.1 pt. wt. water-reducing agent and 100-140 pts. wt. water.
