Formation of intermediate phases during hydration of C3S

The described model concepts can be employed as the basis for the development of binding agents possessing a significantly lower energy content and thus generating lower specific carbon dioxide emissions.

1 Introduction

The setting of cement is an important technological process. Nowadays, more than 2 billion t of cement are manufactured and processed all around the world. In addition to the technological parameters of the produced cements, such as water demand, setting times and compressive strength development, the industry places very great importance on the environmental impact of the cement manufacturing process. The main focus is placed on carbon dioxide emissions and the consumption of thermal and electrical energy. It can be assumed that cement production capacities will continue to...
