Approches sur le procédé de renforcement des ksour avec formulation et optimisation d’un matériau composite

Abstract

Heritage presents an inestimable wealth, which must be safeguarded and protected to be transmitted to future generations, as proof of historical existence. The architectural and urban heritage in the Algerian Sahara, especially the ksour, is certainly an undeniable cultural production. The ksar is, by its architectural and urban value, one of the historical landmarks of current Saharan cities, which sadly continues to sink into neglect, where a considerable part of this heritage is in agony and risks an imminent disappearance; among these ksour we note that of Ouargla. This ksar continues to deteriorate because of rehabilitation operations that remain punctual or partial and are sometimes abandoned for lack of skills and adequate, for this, the implementation of a methodology of intervention of rehabilitation is needed to strengthen this architecture in order to safeguard it. The reinforcement techniques are multiple, vary according to the structures, the constructive systems and the materials, the good rehabilitation requires a good knowledge of its last in order to choose the most adequate reinforcement approach, always respecting the sensitivity and the specificity inheritance in order to maintain its authenticity and its architectural and heritage character. Our case study approach is the operation of rehabilitation of the Ksar de Ouargla for the historical values architectural and cultural it presents, which we will be interested in the techniques of reinforcement against the pathologies which the threat whose objective is to preserve and enhance this heritage
