In order to further optimize mix proportion design of fly ash concrete, improve the construction technology and the quality of concrete, according to the complex non-linear relationship between fly ash concrete strength and its influencing factors and analyzing the main factors of affect the strength of fly ash concrete, a prediction model based on the projection pursuit regression analysis for the strength of fly ash concrete is proposed, the best projection direction is found using the simplex optimization algorithm, and the corre-sponding calculation program is compiled under the Matlab. The strength of fly ash concrete will be predicted by the use of relevant data measured. It shows that this method has a high fit, good prediction accuracy, and applicable to practical engineering.
