The Influence of Ground Fly Ash on Cement Hydration and

In this study, the ground fly ash is made of ordinary grade I fly ash by grinding. Compared with grade I fly ash, the influence of ground fly ash on cement hydration and mechanical property of mortar was investigated. The results show that ground fly ash can improve the hydration of cement at all the ages compared with grade I fly ash, and not only does its pozzolanic reaction start earlier

Cement Manufacturing Process: What is Cement made of

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

Climate Change Mitigation - CRH Cement

Slag cement creates a concrete with higher overall strength and durability resulting in decreased life cycle costs. The end result is a product with an overall lower carbon footprint. Clinker substitution is the most direct way to reduce the greenhouse gas impact associated with cement manufacturing as it bypasses the thermal process completely.

Cement - History of cement | Britannica

Cement - Cement - History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in western Europe. Volcanic ash
