We use secondary materials (SMs) in #clinker, #cement & #concrete production to reduce CO2 emissions. Increasing their use requires:
🔸access to sufficient amount of SMs
🔸pretreatment of potential SMs
🔸compatibility of the chemical composition of the SMs with clinker & cement

What are the secondary materials used in clinker, #cement & #concrete production?🤔
🧱 Alternative Raw Materials: wastes from other sectors
🏗️ Supplementary Cementitious Materials: contributing to concrete through hydraulic or pozzolanic activity
Why?🤔 To reduce CO2 emissions!
