The structure (10) comprises construction blocks (12, 12a, 12b) formed from a non-reinforced concrete comprising a binder and an eco-agglomerated granules, and a spacer (18) to maintain a predetermined spacing between the construction blocks. The eco-agglomerated granules are free of a metallic element, and comprises reinforcement fibers (0.2-1%)and shell sand (15-50 wt.%) that is composed of aggregates from shellfish waste and has dimensions of 160 mu m to 4 mm. The construction blocks include a rigid reciprocal unit having a female member and a male member. The structure (10) comprises construction blocks (12, 12a, 12b) formed from a non-reinforced concrete comprising a binder and an eco-agglomerated granules, and a spacer (18) to maintain a predetermined spacing between the construction blocks. The eco-agglomerated granules are free of a metallic element, and comprises reinforcement fibers (0.2-1%)and shell sand (15-50 wt.%) that is composed of aggregates from shellfish waste and has dimensions of 160 mu m to 4 mm. The construction blocks include a rigid reciprocal unit having a female member and a male member adapted to cooperate with each other to ensure a structural association of the construction blocks, where the male member is formed by a fiberglass rod that is partially sealed in the non-reinforced concrete. The fiberglass rod is partially housed in the construction blocks to ensure mechanical connection of the construction blocks with the fiberglass rod by the adhesion of non-reinforced concrete and/or a sealant. The female member includes receiving units formed in one of the construction blocks, and the fiberglass rod and the sealant are arranged in an interior of the receiving unit. The fiberglass rod is embedded in the non-reinforced concrete and the spacer to ensure a mechanical connection of the spacer with the fiberglass rod, and is partially housed in the spacer to ensure a mechanical connection of the spacer with the fiberglass rod by the adhesion of non-reinforced concrete and/or the sealant. The receiving units are co-axially formed in the construction blocks. The spacer is structurally distinct from the construction blocks and formed of a material that is different from the non-reinforced concrete. The reinforcement fibers have a length of 1-10 cm. The construction blocks have a body covered by a surface coating formed of the non-reinforced concrete. An independent claim is included for a process for fabricating a structure useful in an underwater environment. |
