Development and characterisation of roller compacted concrete by using marble powder: as partial replacement of cement

Concrete is the most used construction material nowadays, but it poses environmental hazards due to the emission of CO2. One sustainable alternative is the partial replacement of cement with marble powder, a byproduct of the marble industry. This study aims to analyse the feasibility of using marble powder from 5%-15% as a substitute for cement in roller compacted concrete. Mechanical as well as durability aspects were investigated. Optimum dosage for mechanical properties was 5% replacement. Durability study revealed that this replacement is not beneficial for acid attack, but it exhibited resistance to freeze thaw and sulphate attack. By partially replacing cement with marble powder (MP), concrete can attain sustainable development and increased strength.
