Abstract：To investigate the potential utilization of coffee grounds ash in green-growing concrete,green-growing concrete was prepared by replacing cement with coffee grounds ash of equal volume.The effects of coffee grounds ash content of 5％,10％,and 15％on the compressive strength,alkalinity,and porosity of green-growing concrete were studied,and the green-growing performance of tall fescue in coffee grounds ash green-growing concrete was tested.The results showed that the activity indices of coffee grounds ash at 7 and 28 days were 39.7％and 47.9％,respectively.When the content of coffee grounds ash is 5％,the compressive strength of coffee grounds ash green-growing concrete at 7 and 28 days increased by 8.3％and 21.6％respectively compared to the untreated condition.When the coffee grounds ash content is 15％,the porosity of coffee grounds ash green-growing concrete is the highest,at 28.4％.As the amount of coffee grounds ash increases,the alkalinity of coffee grounds ash planted concrete gradually decreases.After 21 days,the growth height and density of tall fescue in coffee grounds ash green-growing concrete increased,and the growth rate was significantly better than that of the untreated group.
