Evaluation of the Mechanical Properties of Normal Concrete Containing Nano-MgO under Freeze–Thaw Conditions by Evolutionary Intelligence

In this research, different amounts of nano-MgO were added to normal concrete samples, and the effect these particles on durability samples under freeze thaw conditions was investigated. The compressive tensile strength as well permeability containing nanoparticles measured compared those plain (without nanoparticles). age percentage nanoparticles, water-to-binder ratio are variables current research. Based results, addition 1% with a 0.44 can reduce up 63% improve strengths by 9.12% 10.6%, respectively. Gene Expression Programming (GEP) is applied, three formulations derived for prediction mechanical properties nano-MgO. method, 80% dataset used randomly training process 20% utilized testing formulation. results obtained GEP showed acceptable accuracy.
