Concrete is the most important material in civil engineering. Its compressive strength is a highly nonlinear function of age and ingredients. These ingredients include cement, blast furnace slag, fly ash, water, superplasticizer, coarse aggregate, and fine aggregate. The test to calculate compressive strength is carried out either on a concrete cube or cylinder through the use of a compression testing machine (2000 kN). The test is destructive and takes a long time, so the possibility of predicting the compressive strength takes on a significant importance. The following figure shows a compressive strength test:

In this study we want to create a model that allows us to calculate the compressive strength according to the ingredients used in the mixture. We begin, as always, by getting the data to be analyzed.
