POROUS GREENING VEGETATION BLOCK FOR LIVER ECOSYSTEM PROTECTION

摘要

A block composition for ecological restoration is provided to simultaneously increase recycling rate of the industrial waste and secure compressive strength of a block for ecological restoration sufficiently by using recycled aggregate and industrial waste including blast furnace slag, waste glass powder, and others. A block composition for ecological restoration comprises: 70 weight parts of aggregate with a unit weight of 1350 to 1450 kg prepared by mixing crushed aggregate having a grain size range selected from 25 to 50 mm, 20 to 25 mm, 15 to 20 mm, 8 to 13 mm, and 1 to 3 mm with recycled aggregate at a mixing ratio of 5:5, 7:3, or 3:7; 30 weight parts of a binder with a unit weight of 450 to 490 kg which includes blast furnace slag-cement, blast furnace slag, calcined loess, and quartz porphyry with a particle size corresponding to a sieve size of 100 to 325 mesh, and with which one or more selected from calcium hydroxide, kaolin, metakaolin and regenerated waste glass powder are additionally mixed; 1 to 1.5 weight part of a water-reducing agent with respect to 100 weight parts of the binder; and 25 to 30 weight parts of water with respect to 100 weight parts of the binder.
