STUDY THE EFFECT OF USING PALM FIBER ON THE PROPERTIES OF HIGH STRENGTH FLOWABLE MORTAR

This paper deals with an experimental investigation of some physical and mechanical properties of high strength flowable mortar reinforced by different percentages of palm fiber (0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4 and 1.6% as volumetric fractions).The density, compressive strength, flexural strength and toughness test were used to determine the mechanical properties of this mortar. Test results show that the inclusion of this fiber reduces the density of mortar. The use of 0.6% of palm fiber increases the compressive strength and flexural strength by about 15.1%, and 16% respectively ,besides, the toughness of the high strength flowable mortar have been improved using volume fraction of 1% and more.
