Mechanical Properties of Silica Fume Concrete in Marine Environment

Abstract

Concrete is a common material used in marine structures. Cement, as a concrete-forming substance, contributes to global CO2 emissions. Reducing cement by adding Silica Fume transforms concrete into green concrete without reducing its quality. Concrete construction in the marine area is commonly affected by abrasive factors such as water penetration, waves, and sea currents. Concrete materials have good quality, as shown by their mechanical properties. This study examined how Silica Fume affected the mechanical characteristics of concrete. The specimens were made with variations of Silica Fume 5%, 7%, and 10% by weight of Cement, then cured with seawater. Tests are carried out for mechanical properties such as compressive strength, flexural strength, permeability, and abrasion mass loss. The test results showed that the compressive and flexural strength values achieved good results, and the weight loss and abrasion coefficient values were better than ordinary concrete.
