A budding material based on calcium hydroxide, in which the main component is lime of the type known as hydrated lime, which is mixed a filler of organic and/or mineral origin to produce a structural mass comprising of the basic component and the filler. A defined volume of water, calculated as a function of the volume of the structural mass, is added thereto to produce a paste that can be worked and is capable of hardening. To ensure setting of the material, an additive comprising at least one powder based on natural materials of volcanic origin is added to the pasty structural mass. The additive is preferably pozzolana and the filler advantageously comprises shavings or fibers of substances, preferably of vegetable origin such as hemp or wood.
