“…They can be a significant raw material for producing nanoparticles used later as absorbers of pollutants [ 12 , 13 , 14 ], especially heavy metals [ 15 ]. They are also used as a substitute material in the production of cement or aggregate [ 16 , 17 ]. Other sources indicate their use as soil conditioners, fertilizers, and absorbents for removing dyes and heavy metals [ 18 ].…”

The paper presents the characteristics of unplasticized PVC composites modified with biofiller obtained from the waste eggshells of hen eggs. The composites obtained by extrusion contained from 10 phr to 40 phr of biofiller. The filler was characterized using the SEM, TG, and sieve analysis methods. The influence of the filler on the processing properties was determined using plastographometric and MFR tests. Fundamental analysis of mechanical properties was also performed, i.e., Charpy impact strength and determination of tensile properties. The mechanical properties were supported with dynamical mechanical thermal analysis, time of thermal stability, and thermogravimetric analysis. Structure analysis was also performed using SEM and X-ray microcomputed tomography (micro-CT). The processing properties of the tested composites do not give grounds for disqualifying such material from traditional processing PVC mixtures. Notably, the biofiller significantly improves thermal stability. Ground eggshells (ES) work as scavengers for the Cl radicals released in the first stage, which delays the PVC chain’s decay. Additionally, a significant increase in the value of the modulus of elasticity and softening point (VST) of the composites concerning PVC was found. Ground hen eggshells can be used as an effective filler for PVC composites.

“…Calcium is one of the Portland cementforming chemicals usually obtained from lime and chalk alone to fill 85% of the cement mass (Citrasari, 2019;Do et al, 2019;Kareem, 2023;Ren et al, 2020;Zhang et al, 2019). CaO oxide is the major oxide which contributed to its formation clinker and the quality of cement produced (Damdelen, 2019;Jiang et al, 2021;Ma et al, 2018;Yang et al, 2022;Yusuf et al, 2021). In the process of making cement, Calcium Oxide is the largest component in quantity, and will react with Silicate Oxide, Aluminum Silicate, Alumina, and Iron Oxide and form mineral compounds that are potential constituents of strength in cement (Halin, 2018;Huang et al, 2019;Sharonova et al, 2019).…”

Candlenut is a superior commodity with great opportunities. Processing of candlenut seeds produces candlenut shells which are hard with a calorific value of 4164 cal/g so can be used as fuel. Processing candlenut shells as fuel produces waste of ash and not been utilized optimally. In this research, candlenut shell ash was used as a new alternative in making paving blocks, namely to substitute sand by 13%, 18% and 25% by weight of sand. The method used to analyze the chemical content of candlenut shell ash through XRF testing and compressive strength testing with a Compression Testing Machine after 28 days of curing time. Based on the results of the XRF test, hazelnut shell ash has a CaO content of 93.3%, where CaO is the main ingredient for making cement. In addition, the results of the average compressive strength of paving blocks at 13% substitution of candlenut shell ash produced a compressive strength of 5.89 Mpa, 18% substitution of candlenut shell ash of 8.72 Mpa, and 25% substitution of candlenut shell ash of 11.07 Mpa. The results of the compressive strength of paving blocks with the substitution of hazelnut shell ash produced standard standard paving block strength of D quality.

“…The sustainable assessment revealed that a 5-percent EP replacement exhibited the best performance and reduced environmental pollution. As pointed out by Yang et al [ 22 ], Eggshell powder has the potential to act as a partial substitute for cement and fine aggregate. Thus, by using EP, it is expected to produce a more environmentally friendly construction material.…”

“…When 5 wt.% eggshell powder is added, its strength is slightly lower than that of limestone and control mortar. Most recently, Yang et al [ 22 ] discussed the mechanical properties of cementitious materials containing EP by using a scientometric analysis method, and the effects of EP on the performance of the cementitious materials were investigated. The results suggested that 25% EP in cementitious materials is beneficial for material performance.…”

Using eggshell powder (EP) to replace partial cement in cement-based materials can abate pollution caused by eggshell discard and cement production. In this paper, the surface property of EP and its influence on cement hydration were studied. Quartz powder (QP) and limestone powder (LP) were used as references. First, the chemical composition of EP was characterized. Then, the surface charge properties of these materials were analyzed using zeta potential measurement. The interactions between EP surface and Ca2+ were discussed based on the zeta potential test. Afterward, a scanning electron microscope (SEM) was applied to observe the morphology of hydrates on the surfaces of these materials. The results indicated that, although the compositions of EP and LP are similar, the surface charge properties are significantly different. This is likely due to the existence of organic matter on the surface of EP and the difference in the atomic structure. As shown from the zeta potential test, EP exhibits similar interaction with Ca2+ as QP. The interactions between EP surface and Ca2+ are much weaker than that between LP and Ca2+. These weak interactions lead to the growth of C–S–H on the surface of EP particles less than that of LP particles. The chemical reactivity of EP can be improved by using heat treatment, electrical oven, etc. This study will provide theoretical support for the better use of EP in cement-based materials.
