Engineering Performance of Cement Mortar Cubes Containing Percentage of Date Palm Fibers and Leaf Ash

The problem of conventional cement mortar cubes is the requirement to be used for their production. It recognized that production involves a significant release carbon dioxide atmosphere, which detrimental quality environment. To adopt sustainable development building materials, date palm tree has been by numerous researchers partially replace in cubes. study aims: 1. optimize engineering properties enhanced with fibers and leaves ash. 2. investigate microstructures chemical characteristics optimized waste design optimization this study, were formulated such way trial mix designs varied ash (1% 10% as partial substitute cement) palm, 5% silica sand). mechanism reaction at early- long characterization tests studied term period curing on paste, including water absorption test, Ultrasonic Pulse Velocity (UPV) compression SEM energy dispersive X-ray (EDX) Fluorescence (XRF). As study's major finding, it was realized optimal ratio treated noticed have 4% 2% sand substitute. There improvement cubes' compared those control outcomes proved both can cause pozzolanic activity reinforcing effect
