Analysis of cement clinkers is a traditional comprehensive experiment that involves the theory and practical application of gravimetric analysis and complexometric titration. Based on several internet platforms, online and offline mixed teaching was explored for effective experimental instruction, a shortened lecture time, and fairly graded experimental data. This method strengthens students' overall accomplishments, pre-lab study abilities, and innovative spirits, while the quality of teaching and impact have improved.

Key words: Comprehensive experiment, Mixed teaching, Cement clinker, Gravimetric analysis, Complexometric titration
