Abstract: The utilisation of coal in the cement and concrete industries takes three basic forms: 1. As a fuel in the production of cement clinker, 2. Ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds, 3. Ash produced by burning coal in power stations is used as a mineral additive in concrete mixes.
