Berhanu Assefa, who generated the idea of the project, consulted me throughout the year. I am grateful to Agrostone Production Center Manager, Mr. Noah that permitted chemical and raw materials for producing the board samples and Mr. Hailemicale, Head of Quality Control and Research Department, consulted and gave information about the production process. I convey my gratitude to Director General of Quality and Standards Authority of Ethiopia (QSAE), Mr. Messay Girma who permitted me to test the samples in the QSAE laboratory and Miss Genet Geberamedihin, Head of Testing and Calibration Directorate, who facilitated the test in laboratories. Finally, I would like to thank my beloved wife Hanna, my families and friends who encouraged me for completing the project
