    Improved mechanical properties of recycled linear low-density polyethylene composites filled with date palm wood powder حسب AlMaadeed, Mariam A.

    منشور في 2014
    "…The presence of filler increased the flexural strength from 11.4MPa for unmodified RLLDPE to 17MPa for the composite containing 70wt.% filler. The Young’s modulus and stress at break measured at 50°C decreased significantly compared with those values measured at 25°C. …"

    Deoxygenation of pyrolysis vapour derived from durian shell using catalysts prepared from industrial wastes rich in Ca, Fe, Si and Al حسب Tan, Y.L.

    منشور في 2020
    "…With same silica-to-alumina ratio, catalyst prepared from oil palm ash (AS-OPA) with lower Fe and Ca contents gave higher liquid yield (8.32 wt%) with alcohols (28.90%), hydrocarbons (46.00%), and nitrogen-containing compounds (21.46%) while catalyst prepared from electric arc furnace slag (AS-EAF) with higher Fe and Ca contents produced lower liquid yield (50.21 wt%) with high amount of esters (25.80%) and hydrocarbons (72.82%). …"

    Combined effects of treated domestic wastewater, fly ash, and calcium nitrite toward concrete sustainability حسب Abushanab, Abdelrahman

    منشور في 2021
    "…OPC paste and mortar with TWW were first prepared and compared with the permissible limits specified in ASTM C1602/C1602M ? 18 provisions. After that, ten concrete mixes were prepared with different ratios of TWW (0%, 25%, 50%, and 100%), FA (0%, 20%, and 35%), and CN (0% and 3%) and tested for fresh slump and density, compressive and flexural strengths, electrical resistivity, porosity, and chloride permeability. …"
