Special Issue Information

Dear Colleagues,

Traditional building materials are very popular. Nowadays, thanks to innovative technology, new properties, advantages, and disadvantages of materials are being discovered. The disadvantages of traditional building materials have increased interest in the use of alternative materials in civil engineering. These alternative materials include production and post-production waste materials from different industry branches. The usage of waste materials as an alternative addition or admixture for traditional materials could help to reduce greenhouse gas emissions, is environmentally friendly, and would help to save the planet. Concrete is one of the most popular traditional materials and can be modified by the addition and admixture of waste materials. To produce an advanced and environmentally friendly material (green concrete), new research, numerical simulations, and design methods are required. These would allow us to discover the properties of new material and thus develop new methods of designing construction elements for different kinds of building objects. The similar dependencies of composites including waste materials can be developed with other traditional building materials such as wood, steel, glass etc.

I would like to encourage you to publish articles related to the aforementioned topics. I look forward to our fruitful cooperation.

Prof. Dr. Jacek Domski

The aim of this study was to develop sustainable concrete by recycling concrete aggregates from steel waste and construction waste (iron ore tailings (IOTs) and recycled coarse aggregates (RCAs)) to replace silica sand and natural coarse aggregates. In experimental testing, the compressive strength, peak strain, elastic modulus, energy dissipated under compression, and compressive stress–strain curve were analyzed. Microscopically, scanning electron microscopy and energy-dispersive spectrometry were employed to investigate the microstructural characteristics of the interfacial transition zone (ITZ), and the results were compared with the ITZs of natural aggregate concrete and recycled aggregate concrete (RAC). In addition, the pore structure of concrete was determined by nuclear magnetic resonance. The results revealed that an appropriate IOT content can improve the ITZ and compactness of RAC, as well as optimize the mechanical and deformation properties of RAC. However, due to the presence of a smaller number of microcracks on the surface of IOT particles, excessive IOTs could reduce the integrity of the matrix structure and weaken the strength of concrete. According to the research, replacing silica sand with 30% IOTs led to a reduction in the porosity and microcracking which resulted in a much denser microstructure. Full article
