NOVELTY - Mortar lining material comprises 60-90 pts. wt. high aluminum cement, 10-30 pts. wt. granulated blast furnace slag micro powder, 5-10 pts. wt. silicon ash, 100-300 pts. wt. sand, 0.1-0.2 pts. wt. water reducing agent, 0.01-0.02 pts. wt. retarder, 0.01-0.05 pts. wt. graphene oxide and 30-50 pts. wt. water. The water reducing agent is naphthalene water reducing agent or polycarboxylic acid water reducing agent. The retarder is citric acid or tartaric acid. USE - The mortar lining material is useful for ductile cast iron pipe lining for sewage (claimed). ADVANTAGE - The mortar lining material: has high density, post strength reduction, good corrosion resistance, low manufacturing cost, cement mortar lining reaches to 6.5 MPa after 90 days, porosity is 8.7% and cracking ratio is 18%; and provides anti-corrosion lining having high strength, wear resistance, strong acid resistance, and capable of inhibiting microbial growth. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: ductile cast iron pipe lining for sewage; and manufacturing the ductile cast iron pipe lining.
