AB  - This study illustrates the utilization of roof tile waste as a resource in the manufacturing of fired bricks. Although commonly referred to as demolition waste, it is technically classifed as construction and demolition waste
(C&D). This demolition waste was used as a partial replacement of two soils (alluvial and laterite soil) at three firing temperatures that were considered economical (700, 850, and 900 ◦C). The waste considered was obtained from roof tiles previously fired at a low temperature below 800 ◦C, thus containing residual carbonates and clay
minerals. The increased waste input resulted in higher firing shrinkage, bulk density, and water absorption while
decreasing loss on ignition. An increase in firing temperature led to higher firing shrinkage, loss on ignition, and
bulk density, but lower water absorption. The bricks met both Indian and ASTM standards for 2nd and 3rd class
by adding 20–35 wt% of roof tile waste and firing at 850–900 ◦C in laboratory and industrial settings. The
minimum acceptable quality for the produced bricks was achieved with an addition of 35 wt% waste, resulting in
a water absorption of approximately 19% and a compressive strength ranging from 6 to 9 MPa. The study suggests that incorporating waste from demolished roof tiles into the production of burned bricks can be advantageous.
It can partially replace the need for soils, reduce natural resource usage, lower energy consumption
during production, and decrease the carbon footprint.

AB  - In this paper, the drying modeling of roofing tiles was done using a "lumped" approach. In other words, several forces that are influencing internal moisture transport are combined to create effective moisture diffusivity. For this reason, the effective diffusivity coefficient was added to Cranck's diffusion equation. In their earlier works, the authors published the solution to the diffusion equation, which assumes that effective diffusivity is constant. It was demonstrated that, particularly if shrinkage is not taken into account during the computation stage, the simulated drying curves differ from the experimental results. The next step was to ascertain the time-dependent effective diffusivity and to more precisely anticipate the drying kinetic. The general functional relationship between effective moisture diffusivity and Fourier number was first determined to fulfill this assignment. Experimental proof of the proposed model was provided. Less than 3% of the outcomes from the simulation and the experiment deviated from each other. This was a resounding affirmation that effective diffusivity is not constant during drying and that all internal transport mechanisms are observable in their time-dependent relation.

AB  - The European Green Deal, which emphasizes zero-waste economies, and waste recycling
in construction and building materials, has arisen due to significant worldwide needs for solid waste recovery and usage. This ambitious study focuses on recycling mixed construction and demolition (C&D) waste into burnt bricks and investigating the influence of firing temperature. While pursuing its objectives, this is dependent on raw material characterization and burnt-brick product quality assessment. The recycling of mixed C&D waste is explored by mixing the waste into two soil types (alluvial and laterite) in ratios ranging from 5% to 45% at three firing temperatures (700 °C, 850 °C and 900 °C). The utilization of mixed C&D waste in amounts of 10% at 700 °C and 25% at 850 °C and 900 °C fulfilled the Indian standard. Although a fire at 700 °C results in less optimal waste utilization, it is beneficial and recommended for reducing the carbon footprint and energy use. Additional mineralogical and microstructural analyzes are performed on the optimal fired samples.
The study’s findings are promising for sustainable resource usage, reducing carbon footprint, and
reducing waste disposal volume. This research is a big step toward the Sustainable Development
Goals of the United Nations and a circular economy.

AB  - The main idea of the present study was to investigate the impact of the ongoing world
crisis on the socio-economic issues in Serbia concerning building materials usage and purchase. This research fills in the gaps in the literature and contributes to the comprehension of how the crisis has affected salaries, market pricing, and materials consumption in the building sector. The data are gathered through a questionnaire and analyzed using a statistical methodology (frequencies, descriptive statistics, and Spearman’s correlations). Most of the former studies investigated the surveys conducted on specialists in the field, while this study analyzed the perspectives of random people. Socio-demographic issues are analyzed along with materials consumption before and after the crisis. A special emphasis is given to ecological awareness and novel materials usage. Additionally, it captures a broad shift in the economy and ecological consciousness in a developing country. The majority of respondents are open to using novel building materials and products, but their choice would largely be influenced by cost, the amount of effort involved, and their understanding of the advantages. Statistical approaches revealed that the crisis has a considerable impact on the markets for construction and building supplies, altering consumers’ decisions when purchasing.
This contribution lays the groundwork for developing countries in the modern world to improve
sustainability and adopt circular thinking. Professionals in Serbia need to have a more eco-aware
mindset and enhance how they provide pertinent information to potential clients. This study is
limited by the number of respondents. For future mathematical modeling and forecasting, more
answerers are needed.
