The moisture buffer capacity of biomass concretes based on rapeseed straw

Résumé

Biomass materials are increasingly being used in both new buildings and renovation work owing to their low energy impact and their good hygrothermal properties. In this paper, a dynamic characterization of hygric behavior of two different rapeseed concrete, an insulating and loadbearing material, is presented. The moisture buffer value (MBV) is measured according to the NORDTEST protocol. Samples are exposed to daily cyclic variation of relative humidity: 8 h at 75% RH and 16 h at 33% RH at 23°C. Results show an excellent MBV value for the insulating material and a good MBV value for the load-bearing insulating material. Peer-review under the responsibility of the organizing committee of the ICMB21.
