“…Eggshell ash (ESA) is another bio-waste material that can be utilized to reduce the cement in concrete production [27]. Eggshells, the byproduct of eggs utilization, can establish an irritation in our current circumstance through unpredictable removal [29]. Additionally, the eggshells which is the hard external layer of an egg make up around 10% of the egg weight with a normal load of 60g [25,26].…”

“…There is a slight addition of moving in egg creation worldwide and it is required to produce more than 8 million tons of eggshell squander each year [26]. Consequently, as the population keep growing, the eggshell waste will keep increasing [26,29]. Moreover, the removal of ES is one of the enormous issues as it can deliver a bothersome smell and hypersensitivities.…”

“…Moreover, the removal of ES is one of the enormous issues as it can deliver a bothersome smell and hypersensitivities. Along these lines, this will bring about understanding environmental issues that may request a legitimate treatment [29]. The eggshell comprises developing layers of CaCO3 that structure 95% of the shell [29].…”

The application of chemical stabilizer in soil stabilization can effectively reduce the negative environmental impact in the construction industry. However, the stabilization of soft clay remains a challenge due to the costly and non-eco-friendly materials such as cement and lime. This research demonstrates the combination of SF and ESA in stabilizing the kaolin soils, based on the basic engineering properties and undrained shear strength (USS). Its effect was studied via the inclusion as cement replacement material in kaolin soil at 2, 4 and 6% (by weight of dry soft kaolin clay soil) of SF and ESA substitutions of 3, 6 and 9% (by weight of dry soft kaolin clay and SF content). The result shows a considerably lower specific gravity (4.9% reduction), reduced plasticity index (PI)(48.4% reduction), decreased maximum dry density (MDD) (5.5% reduction), increased optimum moisture content (OMC)(8.7% increment), and higher USS (68.8%). In conclusion, the combinations of SF and ESA as soil stabilization agents successfully enhance the soil strength of the kaolin opening a route to the low cost and eco-friendly materials in soil stabilization.

The chicken eggshell waste from food processing was synthesized as the hydroxyapatite for fluxing agent replacement in ceramic manufacturing. The main fluxing agents in Thailand ceramic manufacturing are natural potash feldspar (k‐feldspar) and animal bone ash. To overcome the problems of inconstant properties and the lack of k‐feldspar, the hydroxyapatite from chicken eggshell waste was selected as fluxing agent for the enhancement of the ceramic product. In this work, the hydroxyapatite with 0, 5, 10, and 15 wt% was replaced with the k‐feldspar in the ceramic samples. The results revealed the physical and mechanical properties of the ceramic samples with various hydroxyapatite contents were investigated after heat treatment in the temperature range of 1000–1200 °C. The ceramic samples added with hydroxyapatite have higher linear shrinkage and bulk density as compared with the ceramic sample without hydroxyapatite. The apparent porosity and water absorption decreased to near zero after the heat treatment at a temperature of 1200 °C. Moreover, the results showed that the physical properties affected the mechanical properties improvement after the hydroxyapatite addition and heat treatment process.

“…Existen varios tipos de residuos plásticos, siendo el polietileno y el tereftalato de polietileno (conocido comúnmente como PET, de sus iniciales en inglés), los más comunes en las corrientes de desechos, sin embargo, su reutilización está ganando cada vez más terreno en la fabricación de ladrillos ecológicos [7], mezclas de concreto [8], mezclas asfálticas [9] y como aislante térmico [10]. Específicamente, el tereftalato de polietileno reciclado ha sido utilizado en la elaboración de concretos ligeros, con densidades entre 300 Kg/m 3 y 1850 Kg/m 3 [11] y resistencias a la compresión alrededor de 21 Mpa, los cuales, permiten reducir las cargas muertas y las fuerzas sísmicas en las estructuras. La densidad y la resistencia a la compresión de los concretos livianos está altamente influenciada por el contenido (alrededor del 60%) y la granulometría de los agregados finos (tamaño máximo nominal menor a 10 mm) [12], de hecho, cuando se desean obtener resistencias superiores a 21 MPa se requiere el uso de aditivos plastificantes, los cuales, incrementan los costos de elaboración, por encima del 5% con respecto al concreto tradicional [13].…”

Los desechos plásticos marinos y su baja tasa de reutilización contribuyen a la contaminación ambiental, requiriéndose estrategias de valorización. Este trabajo presenta el diseño y la preparación de mezclas de concreto tradicional y con reemplazos del 2.5%, 5%, 7.5% y 10% de los agregados finos por plásticos reciclados del mar. A partir de las mezclas preparadas se elaboraron especímenes cilíndricos de 15cmx30cm de diámetroxaltura, respectivamente. Se evaluó el asentamiento, la densidad, la resistencia y el modulo elástico. Los resultados mostraron que un aumento del contenido de plástico reciclado genera una disminución del asentamiento y la densidad, así como un aumento de la resistencia y del módulo elástico. Los especímenes con sustituciones del 7.5% presentaron la mejor resistencia a compresión (18.19 MPa) equivalente al 90.5% del tradicional (20 MPa). Los resultados encontrados muestran información valiosa para la valorización de desechos plásticos marinos en la elaboración de concretos con resistencias moderadas.
