Cement's Circular Role
Leah discusses the innovative role of cement in the circular economy, highlighting how CO2 injection can convert calcium oxide back into limestone, enhancing precast concrete strength. However, she points out the durability challenges posed by rebar corrosion due to cement's acidity over time. Interestingly, while cement acts as a CO2 sink by reabsorbing carbon over decades, this process can also lead to structural degradation, necessitating careful engineering practices to protect rebar within concrete structures.In this clip
