Protection of the Coastal Shores by Adequate Concrete Wave Breakers

EasyChair Preprint no. 13518

Abstract

Climate change is a pertinent pervasive phenomenon that has been under increasing scrutiny and regulation across the world. The coastal prolonged shorelines are susceptible to the intensifying rise in sea levels and its chemical composition. This work pursued the production of concrete mix adequate for seawater wave breakers subjected to an aggressive environment. To meet this goal, conventional and environmentally friendly concrete mixtures were evaluated. Cement was partially replaced, with different percentages, by various admixtures; sugarcane bagasse ashes, nano clay, quartz, fly ash, and silica fumes with an air-entraining agent, superplasticizer, and water acting as the binding agent in each mix. compressive strength and flexural strength were tested on all mixtures to shed light on the potentially augmented mechanical properties of the mixtures. Moreover, abrasion, chemical soundness, and rapid chloride permeability tests were conducted to determine the prospective improvement in durability. Results reveal that the adjustment of concrete mixtures plays an integral role in enhancing the performance of wave breakers. In addition, the use of supplementary cementitious materials, as well as the use of chemical admixtures, need to be amended to meet both environmental as well as performance criteria.
