Research on characteristics of biomass-based humidity-controlling materials

Carries out experiments of performance, comparison and hysteresis on the biomass-based humidity-controlling material made from biomass waste and additive. The results show that the biomass-based humidity-controlling material is good in performance of adjusting the relative humidity in an enclosed environment, and that compared with usually-used light concrete materials, the biomass-based humidity-controlling material is slightly better in capability of humidity response and meanwhile less in weight thereby being beneficial to saving material and energy used in buildings, and that the performance of the biomass-based humidity-controlling material is largely limited by environmental temperature and its composition.
