The pozzolanic activity of material is the ability to react with calcium hydroxide (Thomas, 2013).According to Massazza (1998), the total quantity of calcium hydroxide with which pozzolanic material can combine depends on the nature and content of reactive phase in the pozzolan, SiO 2 content of reactive phases, ratio of calcium hydroxide and pozzolan, and duration of curing.
Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators. The excavated materials are transported ...
Over recent decades there has been a move away from the wet process to the more energy efficient dry process. In Europe, for example, about 78% of cement production is from dry process kilns, a further 16% of production is accounted for by semi-dry/semi-wet kilns, and only about 6% of European production now comes from wet process kilns.
