“…These results are in good agreement with studies [16,19]. In this case, the optimal dosage of eggshell powder as a replacement for part of the cement is 10%, as in [13,16,19,21], but the performance gains achieved in these works differ. The optimal dosages of ESP according to [10,13,16,18,[20][21][22] are from 5 to 15%.…”

One of the unifying factors for all countries is the large consumption of chicken, and other, eggs in food and other types of economic activity. After using various types of eggs for their intended purpose, a large amount of waste accumulates in the form of eggshells. Currently, this problem exists and needs a non-trivial, original solution. The aim of the work was to fill the scientific gap in the direction of studying the microstructure formation of improved nano-modified environmentally-friendly concrete based on eggshell powder and obtaining a concrete composition for the manufacture of an industrial sample of such a material. An environmentally-friendly concrete was obtained, the characteristics of which were improved relative to standard concrete by modifying it with eggshell powder, for which the optimal dosage was determined. The most effective was the replacement of part of the cement with eggshell powder in the amount of 10%. The maximum increase in strength characteristics ranged from 8% to 11%. The modulus of elasticity increased by 4% compared to the control samples without eggshell powder. The maximum reduction in deformations under axial compression and tension in comparison with the control values ranged from 5% to 10%. The study of the composite’s microstructure nano-modified with eggshell powder, and an analysis of the changes occurring in this microstructure due to nano-modification, confirmed the improvement in characteristics and the optimal dosage of eggshell powder.

“…The effect of independent parameters on one or numerous responses is considered by RSM, which employs partial factorial designs like CCD to generate response surfaces for second-order mathematical models [29]. Mathematical models generated using RSM have been observed to be efficient in predicting the properties of concrete containing waste materials [30].…”

The utilization of waste materials in concrete plays a crucial role in sustainable construction by contributing to environmental conservation and enhancing concrete properties. However, waste management and sustainable construction present significant challenges within the construction industry. This study specifically focuses on the optimization of concrete properties by utilizing Blast furnace slag aggregate (BFSA) as coarse aggregate (CA) and recycled concrete sand (RCS) as fine aggregate (FA). To assess the impact of BFSA and RCS replacement parameters, response surface methodology (RSM) based on central composite design (CCD) was employed. The RSM regression equations generated in this study demonstrated high R2 values (>0.8), indicating their capability to explain the variability observed in the responses. To assess the impact of BFSA and RCS replacement parameters, response surface methodology (RSM) based on central composite design (CCD) was employed. In conclusion, the implementation of RSM enables the incorporation of waste materials into concrete, resulting in waste reduction without significant effects on concrete properties.

“…Even for experiment with only one replacement material, Senthil Kumar and Baskar [29] studied the influence of e-waste on 28-day concrete compressive strength by plotting the replacement percentage and w/c ratio together in surface and contour plot. Similar endeavors involving eggshell powder had also been conducted using output from both single [30] and multiple [31] experimental data sets.…”

This paper aims to thoroughly analyze the effect of polyethylene terephthalate (PET) plastic aggregate on concrete compressive strength using a meta-analysis. Forty-three datasets for concrete containing PET coarse aggregate and 60 data sets for concrete containing PET fine aggregate were collected. The input variables used were percentage and nominal maximum size of PET aggregate along with the concrete mix proportions. Main effect plots, contour plots, and surface plots of the expressions were presented to demostrate the effect of PET aggregate on the 28-day compressive strength of concrete. The statistical parameters of the regression equations, such as R2, adjusted R2 and root-mean-square error (RMSE), indicated that the RSM approach is a powerful tool to describe the change of concrete compressive strength by PET aggregate addition. In addition, the study showed that using PET plastic as a fine aggregate replacement performed better than using it as a coarse aggregate replacement in concrete. At up to 30% replacement, concrete containing PET plastic as a fine aggregate can have satisfactory compressive strength.
