Replacement of Fine Aggregates in Fine-Grained Concrete by Waste Material from Cetris Boards Production
Given the increasing amount of waste in the world, it is essential not only to reduce waste generation but also to explore potential uses for the waste produced. This includes waste generated in the production of building materials. The construction industry is a significant contributor to global waste and carbon dioxide emissions, making it crucial to address these issues for sustainable development. During the production of CETRIS boards, approximately 7 600 tons of waste are generated annually. One of the waste materials obtained during the board processing is a fine powder. This waste material can potentially be reused in two ways: it can be incorporated back into the process of producing CETRIS boards or utilized in the production of building materials. This research project focuses on examining the possibility of using this waste material as a substitute for fine aggregate in fine-grained concrete. To investigate its viability, the waste material underwent testing for dry density and absorbency. Subsequently, a reference mixture and concretes with different replacement rates (50%, and 100%) of natural fine aggregate were produced to create self-healing concrete mixtures. The study examined the density, and compressive strength of these concrete samples 28 days after concreting. The findings indicated that as the amount of waste material in the concrete increased, the measured properties decreased. However, despite the decrease, the compressive strengths of the concrete remained very high, leading to the classification as high-strength concrete. Further exploration and optimization of the replacement rates could lead to the development of environmentally friendly and sustainable building materials.
期刊介绍:
Defect and Diffusion Forum (formerly Part A of ''''Diffusion and Defect Data'''') is designed for publication of up-to-date scientific research and applied aspects in the area of formation and dissemination of defects in solid materials, including the phenomena of diffusion. In addition to the traditional topic of mass diffusion, the journal is open to papers from the area of heat transfer in solids, liquids and gases, materials and substances. All papers are peer-reviewed and edited. Members of Editorial Boards and Associate Editors are invited to submit papers for publication in “Defect and Diffusion Forum” . Authors retain the right to publish an extended and significantly updated version in another periodical.
