Moisture transfer in bio-based materials

Application to wood floors on a hempcrete screed

Abstract

Hempcrete is known for its advantages in the field of construction, but the lack of standards on this material leads to a lack of guarantees on site. Nowadays, professionals use a sensible approach to evaluate the drying of hempcrete. The goal of this research is to propose a relevant method to assess the water content by in-situ measurements with usual devices. A wood moisture meter was calibrated for hempcrete in order to monitor the drying of a hempcrete screed and enhance the existing database on the hydric transfer mechanisms in hempcrete.
