“…Egg shells used as a cement substitute are said to reduce costs and carbon emissions by 10-15% (Murts et al 2021). The addition of tea waste as a pore forming agent in the manufacture of ceramic bricks produces hybrid bricks with better thermal insulation, lighter weight and lower compressive strength (Ibrahim et al 2023). Thus, this research offers other uses of egg shells and tea waste as sound absorbing materials in a building.…”

Noise reduction in residential and other types of buildings in urban areas is becoming more important. However, the cost of sound-absorbing materials is still prohibitively expensive for some people. The objective of this study is to create alternative sound-dampening materials from composites made from household waste, specifically egg shells and tea waste. The hypothesis of this study is that because eggshell is a porous material and tea waste is a fibrous material, it has the ability to absorb sound. The sound absorption test was performed in accordance with ASTM E-1050-98, a standard for testing impedance and absorption with a digital frequency analysis system. The highest sound absorption coefficient of the egg shell composite was 0.97 at a frequency of 2392 Hz (NC 35), while the highest sound absorption coefficient of the tea waste composite was 0.592 at a frequency of 1960 Hz (NC 30). The results of the analysis show that both types of composites can be used as alternative sound absorbing materials in residential and similar types of buildings.

“…The mixture is molded into the desired shape, then dried and fired at a high temperature into hard bricks. Firing conditions such as final temperature and heating rates should be adjusted based on the input materials used [26,27]. Although smectite minerals are not used in large volumes due to their higher plasticity and swellability, in smaller amounts they give strength and contribute to the desired vitrification or color properties [17,28].…”

Clay minerals have a great influence on the resulting properties of ceramic bodies. Fly ash as a waste material from burning black coal in power plants is a potentially valuable source of oxides (Al2O3, SiO2 or Fe2O3) for this production. Considering the process of ceramic firing, it is important to understand the thermal behavior of individual ingredients. The thermal behavior of natural smectite minerals (montmorillonite, beidellite, hectorite and nontronite) and their mixtures with added fly ash at different ratios (10%, 30% and 50%) was investigated. The phase analysis was obtained using X-ray diffraction and FT-IR spectroscopy. Under heating to 1200 °C, the structural changes of smectites were divided into four steps including dehydration, dehydroxylation, decomposition and crystallization of new phases. The addition of fly ash caused a shift in the reaction temperatures for all the mentioned phases. These changes were most noticeable for mixtures with hectorite; on the contrary, they were least noticeable for beidellite mixtures. Total mixture mass loss continually decreased with increasing fly ash amount. The obtained experimental thermal data can be applicable not only in the production of ceramic bodies or energy waste processing but also in construction and ensuring the safety of municipal waste landfills.
