Abstract | Pile foundations are the elements of structures used to carry and transmit the structures loads to the bearing ground located at some depth below ground surface. The aim of this paper is to explore the improvement of reinforced concrete piles, subjected to harsh marine environment, because of including supplementary ce-mentitious materials, including fly ash and ground granulated furnace slag (GGFS). The overview showed that fly ash might be the optimum material to be included because it improved the workability, slump, hy-dration process, and it enhanced some mechanical properties such as compressive strength. The main im-provement was in the durability properties. For instance, the permeability and void ratio was significantly improved as well as the internal microcracks were decreased as a results of initial temperature reduction of hydration process. Fly ash replacement ratio should be within a limit, 10-30%. Having a ratio more than these can delay the hydration process; hence, delaying the initial and final setting times. Incorporating ground granulated blast furnace slag was enhanced durability properties such as resistance to chemical at-tacks, chloride attacks, carbonation and it decreased water permeability of concrete. |
