Modification of the Performance of Fresh and Hardened Concrete Reinforced With Fibers From Oil Palm Mesocarp

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 ...

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.

Strength, Sulfate Resistance, and Microstructural Characteristics of Concrete With Partial Cement Replacement Using Eggshell Powder and Wheat Straw Ash

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
This study explores the partial replacement of ordinary Portland cement (OPC) with a composite of eggshell powder (ESP) and wheat straw ash (WSA) in C‐25 concrete, focusing on mechanical performance and durability. Cement was replaced with varying proportions of ESP and WSA, and the concrete mix was prepared following ACI guidelines.

Enhanced Utilization of Coal Ash in Construction: Physicochemical Properties and Compressive Strength of Blended Cement and Geopolymer Mortar

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The properties of fly and bottom ashes produced by Morupule power stations in Botswana are analysed for their pozzolanicity. Furthermore, the influence of physical, chemical and microstructural properties of the ashes on the performance of compressive strength of fly ash–based blended cement and geopolymer mortar was evaluated.
