Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Currently, many researchers use industrial or agricultural by‐products (waste) as raw materials for the construction sector. These wastes are economical and help preserve the environment through good waste management. For this purpose, oil palm mesocarp fibers (OPMFs) are used at various volume concentrations (0%, 0.25%, 0.5%, and 1%) for the ...

Iraqi bentonite as natural pozzolan
Magazine of Civil Engineering, 2022 In this study, Iraqi high-calcium bentonite was used for the first time to prepare natural pozzolan for concrete by the thermal activation method (calcination). Raw bentonite was calcined at 700, 750, 800, 850, 900, and 950°C for 30, 60, 90, and 120 minutes at each temperature.

Performance of Concrete Using Water Hyacinth Ash as a Partial Cement Substitute
Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.Concrete is one of the most widely used construction materials, with cement as its primary component. However, cement production significantly contributes to CO2 emissions, posing environmental challenges. This study investigates the use of water hyacinth ash (WHA) as a sustainable partial replacement for cement in C‐30 grade concrete.
