The ecological consequence created by conventional cement concrete has considerable issues, which need immediate remedies across the construction sector. The advancements in concrete have paved the way for alternatives in partially or fully replacing cement in concrete. One such advancement in fully replacing cement from concrete is geopolymer concrete (GPC).
In this research, GPC is made using ground granulated blast furnace slag, fly ash and alkali activators of Na2SiO3 and NaOH. The experiment was carried out for the stress–strain relationship, and the results of the experimental work were trained using the novel decision honey badger-based relationship prediction approach to determine the optimal values from the experimental data. From the optimal values, the relation between the stress and strain of the GPC model and the peak curve for stress and strain in GPC is developed. Afterward, the models are correlated with recent studies.
The proposed model has a yield point of 1.032004fck at the strain of 0.0045. The suggested model also predicts the stress of GPC at high strain values of 0.0025–0.0045.
In consideration of the above outcomes, the proposed model also predicts stress with greater accuracy.
