The increased demand for infrastructure due to global population growth has resulted in the depletion of natural aggregate sources and escalation cost building materials. There is also problem environmental pollution as a result wastes generated from agricultural activities. This led various studies aimed at investigating use waste materials substitutes aggregates concrete. In this research, sa...

Abstract After pouring concrete precast cavity shell structure has been developing rapidly in recent years, compared with cast-in-place structure, the new fabricated low cost, high construction efficiency, and advantages of green environmental protection, shear wall is most widely used, which includes prefabricated plate shell, annular tendon layout, cast-in-situ important process. But by sever...

Concrete is one of the most widely used building materials today interms physical construction. made from a mixture offine, coarse aggregate, cement, and water with certain ratio, aswell as that are usually added to concrete mixtureduring or during mixing, changing properties tomake it more suitable in jobs economical, can alsobe other mixed needed if deemednecessary. Seashells be mix concrete....

This work proposes a green material for artificial reefs to be placed in Galicia (northwest Spain) taking into account the principles of circular economy and sustainability ecosystem. New concrete formulations marine applications, based on cement and/or sand replacement by mussel shells, are analyzed terms resistance abrasion. The interest lies importance canning industry Galicia, which generat...
