This study applies the genetic programming (GP) theory to predict the slump of high performance concrete. The main factors that influence the slump of high performance concrete are considered as input variables and the slump value is seen as output variable of the GP model respectively. A visible function expression that contains the complex relationship between input variables and output variable is given by applying the method of improved GP and thus a nonlinear mathematical model of high performance concrete slump is built. The performance of the proposed GP model is analysed and the result is compared with that of the linear regression and BP neural network model which show that the GP model has higher fitting precision with the experiment data and better prediction effect. Thus,this new method can be used to predict the slump of high performance concrete.
