équipement de laboratoire d'essai des matériaux

Proetisa’s automated Soilmatic oedometer is an innovative tool replacing traditional "Lambe apparatus" for determination of expansivity in a soil.

Lambe test - Determination of expansivity in soils (Soils Volume Change)

This test is carry out in order to identify quickly soils with problmes of expansivity (volumen change), due to changes in their moisture content. It consist in recognize the expansivity shown in a soil specimen, before compacted, with a previously set moisture conditions up.
