Abstract: Taking the innovative experiment of broken bridge self-insulating blocks as an example, nine specific experiments have been established. They include block type design of self-insulation block, thermal insulation slurry made of waste polystyrene foam, experiment on mix proportion of concrete for block, experiment on compressive strength and flexural strength of block, experimental study on heat transfer coefficient of self-insulating block wall and so on. Students participated in multiple innovation competitions, such as national energy conservation and emission reduction competition and Shandong science and technology innovation competition and won awards according to this innovative experiment. Students also wrote patents A broken bridge type self-insulation concrete block and obtained authorization and published papers in core journals. This innovative experiment enriched the content of the students' experiments, promoted the students' scientific research ability, innovation ability and team spirit. At the same time, suggestions for innovative experimental development were put forward.
