Comprehensive experiments can improve not only the students' experimental skills, but also their understanding of the basic process of chemical research. Furthermore, comprehensive experiments can cultivate students' independent scientific research ability, which is paid more and more attention by college educators. In this paper, a comprehensive experiment is designed:the surface modification of fly ash is carried out and the modified fly ash is replaced with light calcium and carbon black as rubber filler. The experimental data show that the surface-modified fly ash has a better reinforcement effect on rubber. At the same time, using modified fly ash as rubber filler can reduce industrial cost and have great economic and social benefits.
