▎ 摘  要

NOVELTY - An anti-seepage-filled lightweight aggregate insulation concrete comprises 6 pts. wt. nano mild heavy calcium powder, 48 pts. wt. Portland cement, 38 pts. wt. quartz sand, 8 pts. wt. fly ash or slag powder, 9 pts. wt. sepiolite, 2.8 pts. wt. water-repellent dispersible latex powder, 2.2 pts. wt. permeable crystalline active masterbatch, 1.3 pts. wt. polyester fiber, 3.7 pts. wt. powdery acrylic emulsion modifier, and 0.8 pt. wt. carboxylated graphene powder. USE - Anti-seepage-filled lightweight aggregate insulation concrete (claimed). ADVANTAGE - The concrete has excellent crack resistance, high impermeability and high heat preserving effect. DETAILED DESCRIPTION - An anti-seepage-filled lightweight aggregate insulation concrete comprises 6 pts. wt. nano mild heavy calcium powder, 48 pts. wt. Portland cement, 38 pts. wt. quartz sand, 8 pts. wt. fly ash or slag powder, 9 pts. wt. sepiolite, 2.8 pts. wt. water-repellent dispersible latex powder, 2.2 pts. wt. permeable crystalline active masterbatch, 1.3 pts. wt. polyester fiber, 3.7 pts. wt. powdery acrylic emulsion modifier, and 0.8 pt. wt. carboxylated graphene powder. The particle size of nano mild heavy calcium powder is 1000-1200 mesh. The length of polyester fiber is 10-15 mm, and diameter is 20-25 mu m. The particle size of carboxylated graphene is 500-600 mesh. An INDEPENDENT CLAIM is included for preparation of anti-seepage-filled lightweight aggregate insulation concrete.
