Valuation of Palm Fibers in the Formulation of Prefabricated Concrete in Southern Algeria

Abstract

Algeria has known various models of construction. The general observation is the failure of construction models used not only for their inability to meet the growing demand for housing, but also for the destruction of the architectural and urban landscape. Considering the ability of natural fibers improve the mechanical properties and durability of concrete, a renewable resource and permanently available. To this end, researchers have started to search for the most durable materials that respect the environment. The objective of this research is the study of the effect of date palm fibers in cementitious compositions with various proportions on the mechanical characteristics of prefabricated concretes in southern Algeria. The experimental study focuses on the use of local materials (CEMII Class 42.5 R cement, sand, gravel (7/15 and 15/25) and palm fiber with a water/cement ratio of 0.55). The results show that fiber concrete with a length of 5 mm and a dosage of 0.5% is beneficial for prefabricated fiber concrete.
