“…Several researchers investigated the properties of concrete incorporating waste materials using experimental testing (Balasubramaniam & Stephen, 2022;Brekailo et al, 2022;Kabir et al, 2016). Other studies used regression analysis to predict the properties of green concrete (Naser et al, 2022;Waghmare et al, 2022).…”

Concrete industry is challenged by sustainability and technical concerns. Sustainability includes minimization of raw material usage, energy consumption, and emission of greenhouse gases, while technical concerns comprise the enhancement of mechanical properties and durability such as compressive strength, resistance to chloride, acids, and elevated temperatures. Therefore, recycling of industrial waste in manufacturing of green concrete has become a robust viable alternative to disposal, due to the limited natural resources and raw materials which contribute to sustainable construction. Consequently, this research aims to develop an approach using a multicriteria decision-making algorithm based on Analytical Hierarchy Process (AHP), to select the most suitable industrial waste to achieve the desired green concrete properties. The research starts by determining the alternatives including 18 industrial wastes, and the criteria including 14 properties of concrete. After that, an experimental database for the influence of the alternatives on the criteria is established based on the literature. Then, an algorithm is developed using a python script to analyze the influence of incorporating each of the industrial waste alternative on both the mechanical and sustainable properties of concrete. Subsequently, the efficiency of the proposed algorithm is validated using three case studies that present different circumstances of concrete specifications. Based on the proposed approach, the decision-maker can assign the appropriate residual waste to be incorporated into the concrete mix according to its application in a user-friendly manner. Such approach can support both sustainable use of waste materials and enhancement of concrete properties.

“…On the basis of the outcomes of the experiment, regression models were created. The performance of bottom ash concrete improved when granite powder was added [28]. The impact of natural zeolite on the concrete's strength qualities by multiple regression analysis using SPSS tool to provide formulas for strength prediction was performed.…”

The study compares the durability of Natural Zeolite with Metakaolin, Silica Fume, and Fly Ash on high-strength concrete. 300 concrete specimens were tested for compressive strength before and after an acid attack, modulus of elasticity, water absorption, and rapid chloride permeability. 5%, 10%, and 15% of the cement were replaced with cementitious elements while maintaining the same quantity of Natural Zeolite. In this investigation, the water-cement ratio was maintained at 0.35. After 28 days, the specimens were tested for durability. Samples of all mixes were TG/DT and FTIR tested. The optimal percentages of cementitious materials that resulted to the maximum durability enhancements were reported as the study results. Experimental results showed that Natural Zeolite and Metakaolin strengthened the durability of concrete. All the data show that 5% Natural Zeolite with 10% Metakaolin performs well. Good R2values and appropriate independent variable coefficients suggested that the regression findings for high-strength concrete durability were accurate. The P values of all models were less than 0.005 and the F values were statistically significant and appropriate; therefore, the generated models predict concrete's strength with authenticity.
