A Study on the Interlocking Block Using Oyster Shell Powder as Aggregate

굴 패각 분말을 골재로 사용한 인터로킹 블록에 관한 연구

During the molding process of the existing interlocking block, the pigment is firstly laid, and cement is poured on the pigment secondly to give vibration. Interlocking blocks made of conventional cement are entirely dark where the pigment area is removed. On the other hand, when looking at the mortar with oyster shells added, the color is closer to that of the existing cement mortar. Therefore, if an interlocking block is produced by adding a pigment to a mortar with an oyster shell added, it is considered that the amount of pigment is less than that of the existing interlocking block. This study is a basic study of interlocking blocks. To investigate the strength characteristics of mortar using oyster shell powder as aggregate, W/C is 25%, 50%, oyster shell replacement rate is 0%, 25%, 50%, 75%, 100% was substituted to make a mortar and its strength change was studied.
