This work deals with characterizing concrete based on baobab trunk fibers for thermal in- sulation in buildings. The aim is to study the effect of the fiber content and the type of fiber treatment on the hygroscopic and thermo-physical properties of the concrete. Therefore. two types of treatment were carried out: an alkaline treatment and a thermo-alkaline treatment. https://parisnaturalfoodes.shop/product-category/magnesium-citrate/
