Abstract
Experiments were conducted in a low-tide zone to assess the development and application of a carbon-blend mortar coating method and an artificial algal bed of carbon fibers to improve a shallow coastal environment. Carbon fibers, with particles of coke, bamboo charcoal, and iron were used as a carbon blend material. The carbon fiber coating plate showed a high algae coverage rate of greater than 60% because of growth of Colpomenia sinuosa and Colpomenia bullosa. The algae coverage rate of other material coating plates and blocks were less than 30%; plain concrete showed no algae growth. Large amounts of sludge tend to adhere to the carbon fibers. The activated sludge on artificial algae of carbon fibers attracts and cultivates marine organisms, which inhabit the base of algae. It is possible to develop artificial reefs to improve shallow coastal environments through a combination of these characteristics.
