Discussion and promotion of the current situation of Taiwan's construction materials circular economy development We used short-term exchanges to let students know the contribution of Taiwan's construction materials field to the circular economy. For example, how to reduce carbon emissions in the cement industry, how to achieve a circular economy in the concrete industry, and understand the teaching and research status of Taiwan's higher education in the field of civil engineering. The research topics of my laboratory mainly focuses on the sustainable utilization of concrete materials, soil improvement to reduce soil liquefaction. Welcome to join us.
