Effect of silica fume and lathe scrap on properties of Eco-friendly High performance Concrete

Significant world search for the latest solutions for ecological problems to use for waste material that pollutes the environment and is harmful to it. In this work, we utilize eco-friendly material silica fume as a binding material and lathe scrape, which have enhanced properties of eco-friendly high-performance concrete. In this work, we focused on some mechanical properties of eco-friendly high-performance concrete and found that 5% silica fume and 1% lathe scrap enhance the mechanical properties of concrete. Silica fume and lathe scrape also enhance the workability and setting time of eco-friendly high-performance concrete. For this study, a total of 16 samples were prepared and examined: SF 0%, 2.5%, 5%, and 7.5%, and lathe scrape 0%, 0.5%, 1%, and 1.5%. 5% of SF with 1% lathe scrape enhances compressive strength at 25.8%, flexural strength at 14.35%, and split tensile strength at 11.9%. The combined effect of SF and LS improves the properties of eco-friendly, high-performance concrete and enhances its sustainability. Both materials make eco-friendly, environmentally concern, sustainable, and modern construction materials.
