This article focuses on the analysis of the results obtained through experimental testing. That is, changes in physical and mechanical properties of concrete by adding superplasticizer and hydrophobic additives (in dry and liquid state) to ordinary concrete are presented. For testing, 48 samples were prepared based on a total of 8 compositions. These samples were tested for bending and compression on 3, 7, 14, and 28 days, and the effect of the amount of the above additives on the physical and mechanical properties of concrete was highlighted
