Abstract
A novel composite material called Marble Sludge Powder (MSP) will help the concrete industry save money by using less material. When used as a sand substitute in traditional concrete, marble sludge powder significantly boosts strength without degrading the material's characteristics in both the fresh and hardened states. Marble sludge powder is used to partially substitute sand in a concrete mixture. After being cast and allowed to cure for 28 days, cubes, cylinders, and prisms are tested for compressive, split tensile, and flexural strength. Using IS 10262:2019, mix design is computed. Marble dusts are added in concentrations of 5 %, 10 %, 15 %, 20 %, and 25 %. Concrete is infused with 1.5 % of polypropylene fibre. After 28 days, the concrete mixtures' compressive strength, split tensile strength, and flexural strength were assessed. According to the experiment's findings, polypropylene fibre and marble muck powder make fresh concrete less workable.
