Using genetic algorithm for optimisation of cracking time during the breaking of concrete bloc with expansive cement

In this paper, statistical, optimization methods like multiple parameter linear regression and genetic algorithm were used to establish a mathematical model of the demolition time (DT). The performance of the model was evaluated using the statistical indicators. The quality of the model was statistically evaluated, with a significant value of the correlation coefficient of 0.99081376, and low errors. Regarding the optimization of the demolition time by the genetic algorithms method, the results obtained are conclusive with a demolition time of unreinforced concrete of (17 h) which is lower than the demolition time obtained experimentally (36 h).
