Due to several deterioration of coral reefs around the world, h as increased the need to rehabilitate marine environments. Arti ficial reefs have been proposed as a tool for conservation of these ecosystems. A s part of an initiative to develop modules forming artificial r eefs made of ecological concrete for the conservation of the biodiversity in the Colombian Caribbean; this work constitutes a starting poin t. 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 biolog ical and physicochemical evaluations of the material exposed to marine environment was concluded that this is a favorable substrate fo r the coral reefs, and the plates were colonized by more than 3 0% of its surface by marine organisms, their structure found internally stable, a nd there were no adverse effect s on marine biota near the test site.
Debido al deterioro de los arrecifes de coral en todo el mundo ha aumentado la necesidad de rehabilitar los entornos marinos. Los arrecifes artificiales se han propuesto como una herramienta para la conservación de estos ecosistemas. Durante once meses se sumergieron dos placas en forma trapezoidal, en Bajo Grande (Isla Palma), Caribe Colombiano. Esto se realizó como parte de una iniciativa para desarrollar módulos formadores de arrecifes artificiales. Se fabricó un mortero ecológico donde se reemplaza el uso de agregados naturales por residuos cerámicos. Las placas expuestas al medio marino fueron colonizadas por organismos en un 30% de su superficie aproximadamente, la estructura interna de las muestras se mantuvo estable y no se apreciaron efectos adversos sobre la biota marina cercana al lugar de prueba. Después de hacer evaluaciones biológicas y fisicoquímicas del material expuesto se concluyó que éste constituye un sustrato favorable para el desarrollo de los arrecifes artificiales.
