Courte description:

Measurement of the deformations of a 5 x 1 x 0,5 m concrete tendon subject to pure traction loading.

Objectifs de contrôle:

This experiment was designed to test the waterproofing characteristics of different types of concrete.

Nombre de capteurs:

20

Résultats:

The SOFO system measured the shrinkage of the three central meters of the elements during the first month after pouring and during the traction test. Fifteen centimeter long sensors with junction piece coupling also measured the crack’s width evolution inside the element.
