Biological and physicochemical evaluation of mortar as substrate for manufacturing artificial reef. Bol. cienc. tierra [online]. 2016, n.40, pp.55-63.

Due to several deterioration of coral reefs around the world, has increased the need to rehabilitate marine environments. Artificial reefs have been proposed as a tool for conservation of these ecosystems. As part of an initiative to develop modules forming artificial reefs made of ecological concrete for the conservation of the biodiversity in the Colombian Caribbean; this work constitutes a starting point. During eleven months two trapezoidal plates were submerged near to Isla Palma, Colombian Caribbean; plates were fabricated in concrete with portland cement and the aggregates were replaced by ceramic waste. After biological and physicochemical evaluations of the material exposed to marine environment was concluded that this is a favorable substrate for the coral reefs, and the plates were colonized by more than 30% of its surface by marine organisms, their structure found internally stable, and there were no adverse effects on marine biota near the test site.
