2022-4-21 What Is Clinker? Simply put, it’s limestone and clay (or another alumino-silicate substance) that have been bashed into tiny bits and then super-heated so they form a lifelong bond with each other. The crumbly combo forms the main bulk of Portland Cement and is responsible for binding everything together when mixed with sand and water.
