Method & Evidence

AimTo investigate the mechanical properties of concrete when palm kernel shell ash (PKSA) is used as a partial replacement for ordinary Portland cement (OPC).
MethodExperimental research
ProcedureConcrete specimens were prepared with varying percentages (5%, 10%, 15%, 20%, 25%, 30%) of PKSA replacing OPC, maintaining a water/binder ratio of 0.65. The compressive and tensile strengths of these specimens were tested at different hydration ages (above 28 days, specifically at 60 and 90 days).
SampleNot explicitly stated, but multiple specimens for each replacement level and age would have been used.
ContextConstruction materials, waste management, agricultural by-products.

Variables

IVPercentage of Palm Kernel Shell Ash (PKSA) replacing Ordinary Portland Cement (OPC).
DVCompressive strength of concrete, Tensile strength of concrete.
CVWater/binder ratio (0.65), Hydration age (60 and 90 days), Type of cement, Aggregate type and proportion.

Paragraph starter

This study by Amartey et al. (2023) demonstrates that incorporating up to 15% palm kernel shell ash (PKSA) as a replacement for ordinary Portland cement in concrete significantly enhances mechanical properties, such as compressive and tensile strength, particularly at later hydration ages. This aligns with sustainable design principles by valorizing agricultural waste, reducing landfill burden, and potentially decreasing the carbon footprint associated with traditional cement production, making it a viable option for eco-conscious material selection in construction.
