Degradation and mechanical properties of concrete made with metallurgical sludge waste in long-term
Metallurgical sludge waste (MSW), a by-product of mining, energy, and metallurgical industries, has shown potential as a substitute for traditional aggregates. This research article focuses on studying the properties of concrete incorporating MSW itself and recycled concrete aggregate (RCA) containing MSW at both early and late ages. Great emphasis is placed here on the tests carried out one year after concreting. A total of ten concrete mix proportions were prepared with varying amounts of MSW and RCA, including a reference mix. In order to investigate the effects and role of MSW on the durability properties of concrete mixes, several laboratory tests, their numerical evaluation and energy dispersive spectroscopy were carried out. The investigation aims to provide insights into the performance, durability and long-term behaviour of MSW concrete.
期刊介绍：
Materials and Structures, the flagship publication of the International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM), provides a unique international and interdisciplinary forum for new research findings on the performance of construction materials. A leader in cutting-edge research, the journal is dedicated to the publication of high quality papers examining the fundamental properties of building materials, their characterization and processing techniques, modeling, standardization of test methods, and the application of research results in building and civil engineering. Materials and Structures also publishes comprehensive reports prepared by the RILEM’s technical committees.
