Phase 2: Shrinkage of mortar and concrete
This report deals with autogenous shrinkage of two concretes and the corresponding mortars. The theory of self-desiccation and autogenous deformation is presented. Autogenous shrinkage of mortar is measuredin a paste dilatometer at constant and varying temperatures. Similarly the autogenous shrinkage of the concrete is measured in a concrete dilatometer developed in this project. The results are discussed in relation to thermal expansion, activation energy and maturity transformation.
