The aim of investigating Prosopis Juliflora ash in relation to concrete is to assess its impact on the compressive and flexural strengths of the concrete. Prosopis juliflora, commonly known as Mesquite or Ghaf, is a fast-growing invasive species found in arid and semi-arid regions. Its wide distribution and rapid growth have made it a significant concern for environmentalists and land managers. This study aims to explore the potential use of Prosopis juliflora ash as a partial replacement for cement in concrete production and assess its impact on concrete compressive and flexural strengths. The investigation involves both chemical and mechanical characterization to understand the behavior of concrete with varying levels of Prosopis juliflora ash. M30 concrete mix is a type of high-strength concrete with a characteristic compressive strength of 30 megapascals (MPa) or approximately 4350 pounds per square inch (psi) after 28 days of curing. The "M" in M30 stands for "Mix," and the number following it represents the target compressive strength of the concrete mix in MPa.
