Cement and Lime Tunstead
The Tunstead site is home to one of the largest limestone quarries in Europe, producing over six million tonnes of stone a year. The process is highly efficient as the extraction of limestone, production of lime and cement are all intrinsically linked and over 99% of quarried material is converted into saleable products and the remainder is used on site for restoration purposes.

Composite Cement - an overview ScienceDirect Topics
Composite Cement. Composite cements are cements in which a proportion of the Portland cement clinker is replaced by industrial by-products, such as granulated blastfurnace slag (gbs) and power station fly ash (also known as pulverized-fuel ash or pfa), certain types of volcanic material (natural pozzolanas) or limestone.
