- Title
The use of digital images to determine deformation throughout a microstructure Part II Application to cement paste.

- Abstract
The deformation mapping technique (DMT) was applied to the problem of studying shrinkage in cement paste during drying. The results are used to help refine our understanding of the mechanisms that cause shrinkage for different relative humidity ranges. The influences of the age, water : cement ratio, and curing temperature on drying shrinkage are examined. In all cases, shrinkage of bulk samples results from the interaction between expanding regions (rarefactions) and contracting regions (compactions) within the microstructure. Very large local deformations are associated with the collapse of the colloid networks of C-S-H. Damage, akin to fracture, is observed in stiffer samples.
