Abstract

Recently, as the amount of coffee consumption increases, the amount of spent coffee grounds increases, but the amount recycled is small and utilization in the construction field is insufficient. Therefore, in this study, the properties of mortar and the quality of bricks were evaluated by replacing a part of the amount of cement used with spent coffee grounds coated with a water repellent. As a result, the mortar incorporating the spent coffee grounds coated with the water repellent improved the compressive strength, density and absorption ratio compared to the mortar incorporating the spent coffee grounds not coated with the water repellent. In addition, the quality of the bricks manufactured based on the appropriate replacement ratio of the water repellent coated spent coffee grounds satisfied all KS standards. Therefore, it is considered that the appropriate W/B for manufacturing bricks is 38%, and the appropriate replacement ratio of water repellent coated spent coffee grounds is up to 6%.
