    Prediction Of The Compressive Strength Of Recycled

    Recycled aggregate concrete RAC, due to its high porosity and the residual cement and mortar on its surface, exhibits weaker strength than common concrete. To guarantee the safe use of RAC, a compressive strength prediction model based on artificial neural network ANN was built in this paper, which can be applied to predict the RAC compressive strength for 28 days.
