Why are Elastic Moduli Important for Concrete?
The elastic moduli prediction code is set up to compute the elastic moduli of an arbitrary material. As long as the microstructure can be represented by a 3-D digital image, and the individual phase elastic moduli are known, the program can be used to compute the overall moduli. The overall elastic moduli are functions of the microstructure as well as of the elastic moduli of the individual chemical phases in the cement paste. These can be as many as 20 or 30, since cement paste by itself is a chemically complex material.
