Flexural properties of reinforced date palm fibres concrete in Sahara climate

The mechanical characteristics of fibres reinforced concrete depend on many factors which are; the conditions of the work, the dosage, the distance between fibres and their orientation and distribution in the concrete.There are also other factors concerns the fibres themselves such as: the proportion of the length of the fibres to their diameter, their nature, the mechanical characteristics and the geometrical form.The main objective of our work is to contribute in the estimation of the vegetable fibres of the palm-trees that exist too much in our region and to introduce them scientifically in the domain of construction with taking into consideration the climatic conditions of the use.In this work, we will study the effect of the palm fibres on the mechanical characteristics of the concrete, such as: the strength of tensile by flexion.
