Szukana fraza: [Abstract = "Hardened properties were investigated through the compressive strength, flexural strengths, pulse velocity, elastic modulus and water absorption. The obtained results showed that the increase in the substitution rate of RTR reduced the fresh and hardened properties of concrete containing marble waste sand. However, with low substitution rates the properties of concrete remain satisfactory and the utilization of RTR and MWS leads to making a green concrete while protecting the environment."]
