This work presents a study about the correlation between axial compression strength and the sclerometric index of multiple concretes. For a direct assessment of the compressive strength of concrete through the sclerometry test, a reliable correlation made with materials that correspond to the evaluated concrete should be available, ideally the development of a correlation curve that can be used nationally. The data used in the study were obtained through bibliographic research, bringing together 829 data with different types of concrete, this diversity being influential in obtaining the correlation. For obtain a good accuracy of the final correlation curve developed, some standard were used to filter the data, in addition to their statistical treatment. At each treatment stage, a new batch of data was formed, totaling three different batches with their respective correlation curves. Through the correlation curve developed after all the data processing, a correlation curve and an effective correction factor were then proposed to estimate the axial compression strength of concrete from the sclerometric index measurements.
