Abstract
This study investigated the development of a more durable and sustainable cementitious composite substrate for oyster reef restoration using recycled oyster shells and low cement content. The effects of concrete mix proportions (w/c ratio, sand content, and cement content) on the physical properties of the hardened concretes were investigated. Increasing the water, sand, cement, and high-range water reducing admixture content improved both the compressive and flexural strength mostly by improving the coating of cementitious materials around the shells. The proposed material for reef restoration is superior in terms of cost, durability, environmental benefits, and carbon footprint.
