- <p>Concrete is one of the most widely used construction materials in the world, known <br>for its strength and durability. Cement is a crucial binding material used in construction, <br>particularly in concrete. It is well known that cement production is not neutral for natural <br>environment among others due to high CO2 emission. Different strategies of mitigation of negative environmental impact of its production are developed. One of the ways is utilization of supplementary cementitious materials (SCMs) in the <br>manufacture of cement and concrete. This study investigates the effect of polypropylene (PP) <br>fibers on the mechanical properties and Workability of concrete incorporating lime sludge as a <br>partial replacement for cement. Lime sludge, a by-product of various industrial processes, not <br>only minimizes cement consumption but also contributes to waste management and reduced <br>carbon emissions. Polypropylene fibers, known for their ability to control microcracking and <br>enhance ductility, are introduced to counteract the brittleness associated with lime-based <br>concrete mixes. Experimental investigations were carried out by replacing cement with lime <br>sludge (5%,10%,15%,20%) while adding polypropylene fibers in controlled dosages <br>(0.5%,1.0%,1.5%) by overall volume. Key parameters such as workability, compressive <br>strength, split tensile strength, flexural strength and rebound hammer test (NDT) were <br>evaluated.</p>
