Concrete is a material made by binding sand and gravel with cement and water, but 8% of global CO2 emissions come from cement production. Additionally, there is a global shortage of sand and gravel, which are essential raw materials for concrete. Our research lab is working towards solving these issues by focusing on extending the lifespan of existing concrete, improving maintenance, establishing ideal recycling methods, and developing next-generation concrete, all in the pursuit of a sustainable society. This project will showcase various innovations, including 100% recycled concrete (including rubble from Ukraine), plant-based concrete, concrete made from plastic waste, materials made from discarded food, and hardened bodies created by using sand as a binder (including desert sand and simulated lunar sand).
