Sustainable construction materials based on recycled asbestos cement wastes

Abstract

Asbestos-containing waste is one of the main problems of the last decade. The management and disposal of these waste products are in fact of great importance to prevent damage to the environment and to human health. This study presents a characterization of asbestos cement wastes, after having been reduced to powder by a high energy milling (HEM) process of 4 hours. The very fine powders acquired at all processing occasions are described to check the mineralogical and morphological transformation of the asbestos stages. A SEM examination together with thermal and mechanical tests are performed to test the effectiveness of the recycling process.The consequences of thermal examinations demonstrate that the endothermic impacts related to the neo-shaped restricting stages significantly increment with relieving time. Moreover, the innovative efficacy of the reusing procedure is assessed by getting ready and testing water powered lime and processed powder-based mortars. The entire test set gives great outcomes as far as the hydration energy and mechanical properties of the building materials examined. Estimations of responded lime around 40% and estimations of compressive quality in the scope of 2.17 and 2.29 MPa, are estimated.
