The Development of Tile Roof from Disposal Materials

Abstract

This research aimed to explore an appropriate mixture of tile roof sheet made from disposal materials to use as an alternative option of low-cost construction. The mixtures were Portland cement type 1 and aggregate of paper pulp and oil palm fibers. The experimental tests were conducted to investigate its engineering properties. The results showed that compressive strength and flexural strength inversely depended on paper pulp quantity and water cement ratio (W/C). The increase in quantity of paper pulp and W/C contributed to the decrease of compressive strength and flexural strength. The mixture mixed with oil palm fibers presented higher flexural strength than that without oil palm fibers. This was because the stringy shape of oil palm fibers could yield a stronger bond. The mixture mixed with oil palm fibers, furthermore, presented better thermal properties than another without oil palm fibers. The appropriated mixture of paper pulp, oil palm fiber and W/C that suitable for producing tile roof were 15, 10 and 0.8, respectively.
