Mathematical modeling for prediction of strength of remixed concrete

The work deals with the prediction of the concrete lab strength by the development of a model which is formed by considering the different parameters affecting the strength of concrete. The Fisher f-test shows that the values of compressive cube strength predicted by the new regression model are very close to those from the experiment strength values, with f-value of 3.44 at 95% confidence level. Hence this new model of regression is useful in the concrete mix design.
