“…In addition, partial replacement of cement with GGBFS results in lower paste volume due to its higher density, and this decrease in paste volume increases friction at the exemplary aggregate-paste interface, decreases cohesiveness and plasticity, and thus leads to reduced workability. This is supported by several studies that have been conducted that state that the use of GGBFS can reduce the workability of concrete [24] [25].…”

“…However, a 10%-30% GGBFS percentage can inevitably reduce the permeability of concrete. The results in this study are from previous studies [6,24,26,27] The ferrocement specimens were subjected to flexural strength tests using UTM as specified in IS 516:1959. Figure 8 and Figure 9 display the graphs of the relationship between the first crack load and the ultimate load with GGBFS.…”

A reinforced mortar type that can be created with a relatively thin thickness is ferrocement. Using ferrocement as a mechanically sound and sustainable building material has produced several benefits, including less use of raw materials, decreased accumulation of waste materials, and reduced greenhouse gas emissions. Cement as a constituent material of ferrocement is an environmentally unfriendly material; therefore, a more environmentally friendly cement replacement material is needed, namely Ground Granulated Blast Furnace Slag (GGBFS). Thus, creating sustainable (green) fertilizers is the main goal of this work. There are three primary stages to experimental work: Using slag cement (GGBFS) in place of partial cement of 0%, 10%, 20%, and 30% is the initial step. The primary reinforcement in the second level is wire-welded mesh, with volume fractions of support (Vf) of 1.2%, 1.8%, and 2.4%. During the final phase, a maximum of three different test objects were tested for compressive strength, water penetration depth, and flexure at a 28-day age. According to the findings, employing GGBFS led to good mortar performance. According to studies on mortar, the percentage of GGBFS utilized in a work may be determined by comparing the GGBFS substitution rates of 10%, 20%, and 30%, which show no differences in tendency. The test findings did not considerably improve the bending strength and cracking behavior of ferrocement reinforced with wire-welded mesh. One of them is influenced by the age of the concrete; at 28 days, the added material GGBFS has not yet reached its maximum strength, which results in a negligible improvement in bending strength and cracking behavior.

“…In response to the above problems, engineers environment-friendly cementitious material that can be used to partially or completely replace cement in concrete [12,13]. In response to the above problems, engineers creatively proposed to use industrial waste slag and other materials with certain activities as cementing materials to partially or completely replace the cement in concrete, so as to alleviate the environmental pollution and resource consumption caused by cement production and promote the sustainable development of the construction industry [14][15][16][17][18]. Gel is an inorganic aluminosilicate compound formed from alkali-activated industrial waste, metakaolin, and other materials containing a large amount of Si and Al, which does not exist in the high-temperature calcination link in the production process, so it will not release harmful components into the air, nor will it produce solid waste that pollutes the environment due to coal combustion [19][20][21][22][23].…”

Using gels to replace a certain amount of cement in concrete is conducive to the green concrete industry, while testing the compressive strength (CS) of geopolymer concrete requires a substantial amount of substantial effort and expense. To solve the above issue, a hybrid machine learning model of a modified beetle antennae search (MBAS) algorithm and random forest (RF) algorithm was developed in this study to model the CS of geopolymer concrete, in which MBAS was employed to adjust the hyperparameters of the RF model. The performance of the MBAS was verified by the relationship between 10-fold cross-validation (10-fold CV) and root mean square error (RMSE) value, and the prediction performance of the MBAS and RF hybrid machine learning model was verified by evaluating the correlation coefficient (R) and RMSE values and comparing with other models. The results show that the MBAS can effectively tune the performance of the RF model; the hybrid machine learning model had high R values (training set R = 0.9162 and test set R = 0.9071) and low RMSE values (training set RMSE = 7.111 and test set RMSE = 7.4345) at the same time, which indicated that the prediction accuracy was high; NaOH molarity was confirmed as the most important parameter regarding the CS of geopolymer concrete, with the importance score of 3.7848, and grade 4/10 mm was confirmed as the least important parameter, with the importance score of 0.5667.
