High-performance concrete(HPC) is a new terminology used in concrete construction industry. Several studies have shown that concrete strength development is determined not only by the water-to-cement ratio but also influenced by the contents of other concrete ingredients. HPC is a highly complex material, so it is very difficult task to modeling its behavior. This research aimed to predict the compressive strength of HPC with multiple linear regression analysis. Mahalanobis Distance(MD) outlier detection method used for the purpose of detecting outlier and increase prediction ability of regression analysis. The detailed procedure of calculating Mahalanobis Distance (MD) is described. The effects of outlier compared with before and after at the multiple linear regression.
