Abstract [eng] |
In recent years, there has been a worldwide concern about sustainable development and the use of eco friendly materials. The application of wheat straw in the construction industry has therefore attracted a considerable interest, as wheat straw can be used as a reinforcing additive in the production of eco buildings or low carbon building materials. Wheat straw contains cellulose, hemicellulose, and lignin as well as organic substrates and extractives, which makes the surface of straw less compatible with the binding material. Many chemical and physical pre treatment strategies have been proposed to increase matrix biomass adhesion and, hence, the ultimate performance of cement free composites. However, the impact of environmentally friendly treatment methods on different wheat species remains undiscussed. Therefore, the aim of this study is to investigate changes in the morphology of two wheat varieties (S1 and S2) after thermal and non thermal treatment. SEM EDS, FTIR and TGA results revealed that the wheat variety and the treatment method both has a significant impact on the morphology of wheat. It was observed that after thermal treatment, the phloem cells of the S2 wheat were more damaged than those of the S1 sample however, the level of wax removal was lower. The non thermal treatment was less effective in removing hemicellulose or other constituents, although it induced the reduction of silicon content on the outer surface of wheat, indicating the destruction of siliceous layers. Results suggest that the S1 straw after thermal pre treatment should be more compatible with the binding material. |
