Experimental teaching is a very important part in the course of civil engineering materials. It plays an extremely important role in mastering the theoretical knowledge and deeply understanding the material properties. According to the characteristics of the course, a diversified training system based on designable experiment is constructed, with designable, comprehensive and innovative experiments as the main content, and verification experiments as the supplement, to combine experiments with practical engineering and professional design competition. An open and flexible laboratory management system is used to match the reform plan. Students' independent innovation ability and ability to analyze and solve practical engineering problems are gradually improved.
