Promote a high quality of play cement with cementitious powder from waste concrete, blast furnace slag and fly ash as sub material to development recycled cement in the way of 700℃ low-temperature heating. As a result, the fluidity test of recycled mortar using recycled cement, the composition of recycled cement to slaking by CaO greatly reduced by sub material added result in increased liquidity. And also, recycled cement with blast furnace slag as sub material is more superior in improvement of compressive strength than without adding cement..
