Roofing Tiles Innovation Based on Seashells, Coconut Fiber and Sodium Lignosulfonate

Abstract

Seashells and Coconut Fiber has many uses other than it's discarded and become waste. The sodium lignosulfonate also can be use as an mixture in the concrete mix in the present and future of construction. In this study, the seashells, coconut fiber and sodium lignosulfonate is presented as improved strength, water reducer and heat resistance additional mixture in innovation of roofing tiles. This product of roofing tiles divided into three sample (30%,60% and 80%) with different ratio of additional mixture. With different ratio of additional mixture it divided again in 3 sample. This study conducted with the aim to produce concrete improvements on the roof tiles by adding new additional materials such as shell powder, coconut fiber and sodium lignosulfonate. The test that been conducted are compression strength test, water absorption test and thermal conductivity test which is the compression strength test sample 1 with 30% additive materials with 10.00 N/mm² is the highest than sample 60% and 80% but this test are not suitable for roofing tiles strength testing. The water absorption result sample 1 with 30% additive materials absorb less water than other sample with 4.2% and standard sample 4.4% which is fulfilled the Malaysian Standard (MS797).For thermal conductivity testing, sample 1 with 30% additive materials has the lowest temperature reading than existing roof tiles nowadays. The overall of the testing shows that the sample 1 with 30% additive materials are the almost succeeded since the water absorption test and thermal conductivity test shows the best reading compared to the existing roof tiles. This study also shows that the additive materials should not be mixed together into one ratio because it will effect the reading result of the testing.
