Abstract
This study tried to predict mechanical behavior of high-performance concrete (HPC), specially the compressive strength of HPC using different data mining methods. HPC is a highly complex composite material and modelling of its dynamics is a real challenge. Moreover, compressive strength of HPC is nonlinear function of its ingredients. The results of several studies have represented that compressive strength of HPC depends on not only water/cement ratio but also some other additive ingredients. It is actually a function of cement, blast furnace slag, fly ash, water, superplasticizer, coarse aggregate, fine aggregate and age. The quantitative analysis in this study were conducted by using Principal components analysis (PCA) and Multiple Regression (MR) methods. For this purpose, some effective statistical analysis and modeling software such as MATLAB, MINITAB and R has been used. Analytical results suggested that Multiple Regression is effective for predicting behavior of HPC based on its compressive strength with respect to different ages.
