| Abstract | ||
| The research aims to study the addition effect of Palm leaves or Rice husk Fibers on the compressive, tensile and flexural strength of local ordinary Gypsum mortar. These fibers were added to Gypsum mortar with ratios of (0.5,1.5,2.5,3.5,4.5,5.5)% from Gypsum weight with (5,15,25,35,45) mm length and (1.25) mm diameter for date leaves,(5) mm length with (1.25)mm width for rice husks to know their effects on the above mentioned mortar properties. (340) test samples were required,(16)samples for reference Gypsum mortar to find its standard consistency, hardening time, compressive, tensile and flexural strength. The rest (324) samples are for the samples of strengthened Gypsum mortar with the mentioned two fibers types for compressive, tensile and flexural strength tests with (108) samples for each test of these tests to know the effect of these fibers on the mortar properties containing them by comparing with Gypsum reference mortar properties. Results showed that the best addition ratio of Palm leaves fibers for Gypsum mortar is (4.5) % of Gypsum weight with(35)mm fibers length for increasing compressive strength by (27.64) %, tensile by (47.93) % and flexural strength by(23.27) % more than its reference strength while the best addition ratio of Rice husk fibers to Gypsum mortar is (3.5) % of Gypsum weight for increasing compressive strength by (25) %, tensile by(38.84) % and flexural strength by(16.81) % more than its reference strength. The addition of these fibers with these ratios and lengths were improved some of the ordinary Gypsum mortar mechanical properties. | ||
