Abstract: The purpose of the research is to determine the influence of Calcined Petroleum Coke as a partial replacement to carbon fiber as an admixture to the electrical conductivity of cement mortar. Related studies were inspected beforehand by the researchers to have greater foresight with the study at hand. The physical and electrical properties of Calcined Petroleum Coke were determined through testing its resistivity and calculating its density, specific gravity and water absorption. The physical and mechanical properties of cement mortar with Calcined Petroleum Coke and carbon fiber were determined through flexural and compressive strength tests, with samples consisting of 0%, 25%, 50%, 75% and 100% of Calcined Petroleum Coke admixture content; The samples were tested consistently on the 7th, 14th, 21st, and 28th curing days. All of the aforementioned tests were applied with multiple trials. Through analyzing the results of the tests and existing data, the comparison between using carbon fiber and Calcined Petroleum Coke as partial admixture to the electrical conductivity of cement mortar was carefully taken into consideration. The findings of the study reveal that the use of Calcined Petroleum Coke as an admixture yielded greater mortar strength while ‘helming’ the resistive capabilities of the carbon fiber; in other words, the use of Calcined Petroleum Coke was found to be more cost-effective than its carbon fiber counterpart. From the data gathered, recommendations were given which will be beneficial to the construction industry and other related studies in the future. Keywords: Cement Mortar, Calcined Petroleum Coke, Carbon Fiber, Conductivity, Resistivity.
I. INTRODUCTION The versatility and worldwide accessibility of concrete make it the world‟s first choice in various types of constructions and structures. Concrete is a composite material that has excellent strength properties and durability but is a poor electrical conductor. Although concrete has existed in various forms, it is still a material with possibilities for compelling innovations. Concrete that is excellent in both mechanical and electrical conductivity properties may have significant applications in various areas. Over a number of years, numerous unsuccessful research efforts were made to develop this type of concrete. Motivated by this challenge, the Institute for Research in Construction (IRC) has succeeded in achieving this goal with electrically conductive concrete, a patented invention that offers future promise for the use in a variety of construction applications.
