Concrete Compressive Strength Data Set

Estimate compressive strength of concrete


This intermediate level data set has 1030 rows and 9 columns. Concrete is the most important material in civil engineering. The concrete compressive strength is a highly nonlinear function of age and ingredients The actual concrete compressive strength (MPa) for a given mixture under a specific age (days) was determined from laboratory. Data is in raw form (not scaled).

This data set is recommended for learning and practicing your skills in exploratory data analysis, data visualization, and regression modelling techniques. It also allows you to practice with non-linear functions. Feel free to explore the data set with multiple supervised and unsupervised learning techniques. The Following data dictionary gives more details on this data set:
