Experimental evaluation of hydric performances of masonry walls made of earth bricks, geopolymer and wooden frame

摘要

This paper focuses on the characterization of the hydric properties of a new construction system in masonry structures composed of extruded earth bricks, geopolymer binder and wooden frame. The study was based on experimental tests such as the sorption desorption isotherms, the water vapor permeability tests on the different materials and the hydric test on a real size wall. The obtained results show the good properties of several materials, particularly in the storage of humidity. The different solicitations applied on the wall allowed to appreciate the ability of a earth brick wall to regulate humidity inside a house.
