Products and systems for the protection and repair of concrete structures - Test methods - Part 4: Determination of shrinkage and expansion; German version EN 12617-4:2002
This European Standard specifies a method for measuring the dimensional stability (i.e. the shrinkage and expansion movement) due to changes in the moisture content of hydraulic mortars or concretes (CC) or polymer hydraulic cement mortars or concretes (PCC) as defined in EN 1504-1. Two methods are proposed, namely a procedure for unrestrained movement and a procedure for restrained movement. The provisons of the standard are applicable to grout, mortar or conrete products or systems with a maximum aggregate size of 10 mm.
