<p>Solid waste materials of concrete artificial reefs include scallop shells, wheat straw and fly ash. In this study, the basic properties (compressive strength and slump) and ecological effects (leaching and carbon fixation) of these materials were investigated. The results indicate that the compressive strength could meet the construction demands when scallop shells replace 40% gravel or 80% sand, fly ash replaces 30% cement, and the addition rate of wheat straw is less than 6% of the cement mass. Leaching experiments reveal that solid waste materials promote leaching of alkaline substances and silicate from artificial reefs. To a certain extent, leaching of alkaline substances could improve the capacity of the AR ecosystem and cope with ocean acidification. Leaching of silicate could alleviate the environmental problem of silicon limitation and promote marine productivity. Preliminary statistics reveal that reusing solid waste as concrete articial reefs could extend the carbon fixation of reef itself. Therefore, the use of wheat straw, scallop shells and fly ash as AR materials has ecological and economic benefits in reducing carbon emissions and expanding waste resource reuse methods.</p>
