A dilatometer for measuring autogenous deformation in hardening portland cement paste

Mejlhede Jensen, O. / Freiesleben Hansen, P.

Abstract Different techniques for measuring autogenous deformation in cement paste are discussed, and a newly developed dilatometer designed specially for measuring this deformation is described. A particular characteristic of the dilatometer is the encapsulation of the cement paste in corrugated moulds. This restricts moisture loss and ensures that the hardening cement paste suffers insignificant restraint. In addition, the encapsulation permits measurements to commence shortly after casting.

Resume On envisage differentes techniques de mesure de la déformation endogène de la pâte de ciment. On décrit un nouveau dilatomètre conçu spécialement pour mesurer cette déformation. Cet instrument a pour caractéristique de permettre l'encapsulation de la pâte de ciment dans des moules cannelés, ce qui prévient la perte d'humidité et gêne de façon insignifiante le durcissement de la pâte de ciment. De plus, grâce à l'encapsulation, on peut commencer les mesures peu de temps après le coulage.
