USE OF DIMENSIONAL ANALYSIS IN CEMENT INDUSTRY

Compressive strength is widely recognized as the most critical property of cement. However, conventional testing methods require a waiting period of 7 to 28 days to obtain compressive strength results, posing a significant limitation in time-sensitive applications. To address this challenge, this research presents a dimensional analysis-based approach for predicting the 28-day compressive strength of cement within 24 hours.This method employs a modified Buckingham-Pi theorem to derive a general equation using only two experimental data points. A novel trial-and-error procedure is introduced, facilitating the development of a universal dimensional analysis formulation. In this approach, one experimental data set, referred to as the control point, is used to generate the dimensional analysis equation, while the second data set, the check point, serves to validate the derived equation. The predicted results obtained through dimensional analysis are subsequently compared with available experimental data.
