· 1. Clinker is a nodular material which is used as the binder in cement products. Cement is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles etc. 2. Clinker is a granular substance containing spherical pellets of diameter 3-25 mm.
· At present, the major raw material for cement production is still limestone, and roughly 60% of the total CO2 emission for cement production is derived from decomposition of calcium carbonate. To cut carbon emission, the cement industry is actively seeking alternative raw materials such as industrial by-products to replace natural limestone.
