Hydration Mechanisms of Portland Cement: Topochemical or Through-Solution Reaction?

When we simulate the hydration process of Portland cement, it is of significant importance to know the hydration mechanisms. Basically, there are two mechanisms for the hydration of Portland cement, viz. Topochemical and Through-Solution Reaction. 1 Topochemical Reaction Concept Immediately after the first contact of the cement with water a calcium-rich silicious clinker would liberate […]

Review of several existing models simulating the hydration of cementitious materials

In the late 1980s, Johnson and Jennings wrote a program which was based on the idea that cement hydration is considered as nucleation and growth of spherical particles in three-dimensional space. HYMOSTRUC was built by K. van Breugel, this model is based on the assumption that the growth of new layers of hydration products is […]

Two main methods to model cement-based materials

With the development of computer technology, increasing attention is being paid to the modeling work of cementitious-based materials. Many researchers have been carrying out the research to better model the hydration of cement-based materials in the last decades. It is obvious that a cogent simulation of the hydration of cement-based materials has crucial role in […]
