||The present study has for object the validation of the use of a plant sociable disposition natural as matrix in the elaboration of building materials. The gum arabic, also known under the name of gum Senegal, in substitution of the cement was used for the manufacturing of tiles in micro-concrete. The experimental methods of the tries said about "clarification" and about " tries errors " served to determine the optimal relationships of the water on the gum arabic ( E/G) and the solution of the gum arabic on the sand (SG/). With these relationships, the tries of control were made on the Romanic tiles of experiments of dimensions 500x250x10 mm3. The results of these tries show us that these tiles are beautiful and good resistant and their physical aspects raise no problem. Besides, the static and modal dynamic analysis by digital simulation confirms these results. However, during their maturation, tiles with the gum arabic must be placed in a hairdryer or in the sun until the glue (mixture of the water and the gum) dries completely. By this study, we can intend from now on to cover our works with these types of tiles. Finally, as these tiles will be exposed to the bad weather, we envisage in prospect to realize a follow-up study to know more about their ageing under the effect of the humidity and of the heat.
