| 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%. |
