ABSTRACT

During the current era, global warming has become an alarming issue resulting due to the rise in temperature around the globe. If the planet continues warming at such an accelerated rate, it would be difficult for people to live creating discomfort and a nearly challenging environment to survive. The plains of Pakistan are primarily tropical. During summer, the temperature soars beyond 50 0C in numerous parts of southern Pakistan, causing several causalities due to sunstroke and electric power load shedding during the summer season from May to August. The primary heat source inside a building is radiation due to direct sun exposure. Hence, it becomes necessary to adopt a new methodology to resist radiations passing inside the building through the roof providing comfort to the tenants. Efforts have been made to lower the room temperature and keep it within bearable limits by introducing new materials in concrete. Therefore, this research work aims to determine the performance of tiles with different materials as thermal insulation. White cement was used with the combination of marble dust, and ceramic powder separately during this investigation. Interesting results were obtained during the peak hours of temperature, where a temperature difference of 8ºC was attained. For example, while considering sandwiched 50 mm tiles (baked and unbaked), the top temperature was 48ºC, and the bottom temperature was 40ºC. The maximum temperature difference was found to be 13ºC when a total of 75 mm thick pure clay and baked clay tiles were used with a combination of white material tiles.
