Development of thermal insulation properties of concrete roof tile by using para latex

Abstract

The purpose of this research is to improve the physical and mechanicalqualities of natural rubber latex tiles. Water: surfactant: surfactant: 1: 2.75: 0.03: 0.30:0.03: 0.04 by weight and added with natural latex. In the ratio of Portland Cement Type 1: Natural Latex is 1: 0, 1: 0.025, 1: 0.05, 1: 0.075 and 1: 0.10. Formed with compression presses at normal temperatures, it was found that the optimum amount of natural latex For concrete reinforced concrete tiles, the ratio is 1: 0.025. The tests in accordance with Thai Industrial Standard TIS 535-2556 are tested in 4 aspects. Dimensional stress test Water absorption test And waterproofness testing The value has passed the benchmark. And low thermal conductivity. Increasing the insulation of the roof as well. Can be used as a prototype product tile, concrete roof, natural latex. To produce commercially And there can be many local latex or rubber latex. To be more useful and valuable.
