We suggest defining autogenous deformation as all the external volume change taking place without any mass change. The chemical shrinkage is the main driving force, but any re-absorption of bleed water and/or absorbed water in the aggregates as well as the aggregate restraint will influence the relation between autogenous deformation and chemical shrinkage. The autogenous deformation may be measured volumetric or linear. In linear measurements the autogenous deformation may be both contraction and expansion, see below.
