The Effects Of Solignum (Wood Preservative) To The Compressive Strength Of Coconut Lumber

Apart from structural wood preservation measures, there were number of different (chemical) preservatives and processes that can extend the life of wood, timber, wood structures or engineered wood. These generally increase the durability and resistance from being destroyed by insects or fungus. This study aimed to evaluate the effect of chemical preservative to the Strength properties of coconut lumber. Most especially to compare the compressive and flexural strength of treated and untreated coconut lumber and to determine if there were significant difference between the coconut lumber with chemical preservative to those with none. Coconut lumber bought were cut into various sizes, a total of 12 samples were used to this study. 6 samples for compression test, another 6 for flexural test. The samples were then grouped into Controlled and Treated specimen. 3 replication were used for each group. Solignum was used as chemical preservative for the treated specimen. Treated samples were soaked for a period of two weeks, while controlled samples were sundried. The samples were then subjected to Compressive and Flexural Strength Test to know the significant differences. The results of the test shows that when treated with Solignum the compressive strength of coconut lumber decreases, while it increases in terms on flexural strength. On statistical analysis there was no significant difference between treated and untreated wood samples. Since there was no significant difference, it can be inferred that the use of Solignum will not affect the Compressive and Flexural Strength of Coconut Lumber.
