Çimento harçlarında ahşap atık kullanımı

It is a well-known fact that CO2 emission generated during cement manufacturing is threatening the global pollution. Since concrete is the second most consumed substance on Earth after water, it is not surprising that a cement industry accounts for around 5 percent of global carbon dioxide emissions itself. Generation of all kinds of wastes is another alarming matter in terms of the environment and health. This study addresses the influence of the use of wood waste on the fresh and hardened properties of cement mortars. Wood wastes used in this study were in the form of wood powder and wood fibre. Physical characterisation namely X-Ray Fluorescence as well as particle size distribution were performed in this thesis. Mechanical properties such as compressive and flexural strength as well as porosity and permeability of cement mortars combined wood wastes were measured. Resistance to freeze and thaw of these mortars are also examined in the thesis. Experimental results have shown that inclusion of wood wastes in cement mortars enhances the mechanical properties of these mortars. Durability characteristics of these mortars were also found to be improved when wood waste is used as substitution material. Combining waste wood in cement mortars have also found to positively influence the cost efficiency of these mortars. The results reported in the thesis do not only provide a more sustainable development of cement-based materials for construction practices but also suggest an approach for the waste management scheme to be recognised particularly for the undeveloped countries.
