Study the behaviour of cement mortar containing jute fiber along with partial replacement of cement with eggshell powder
Keywords: Eggshell powder (ESP), Split-Tensile strength, Jute fiber (JF), Compressive Strength, Flexural strength.
AbstractThe construction industry's key materials are mortar and concrete. Cement is a key component in the production of mortar and concrete. Natural limestone is used to make cement. When limestone is burned to make cement, carbon dioxide gas is liberated as a by-product, which is considered as a greenhouse gas with adverse environmental effects. Waste materials can be used in the manufacture of mortar and concrete to minimize negative consequences and natural resource utilization. In investigations, a powdered form of eggshell passed through a 90µm IS sieve and jute fiber was employed as a partial alternative for cement in the production of cement mortar. Eggshells are abundant in calcium oxide and have a chemical composition similar to natural limestone. The cement mortar is formed with a 1:3 mix ratio. ESP is added in percentages of 0%, 3%, 6%, 9%, and 12% by cement weight. Mechanical properties such as split-tensile, compressive and flexural strength with percent Jute fiber were compared to a nominal cement mortar cube. The ideal fiber length is 5-10mm. According to the findings, increasing the percentage of eggshell powder (ESP) in the mortar mix along with jute fiber (JF) increases the split-tensile, compressive and flexural strength of the cement mortar specimen. The effects of ESP and jute fiber on split-tensile, flexural and compressive strength, weight, water absorption, bulk density, and sorptivity has been evaluated.
