Use of Marble Dust in Polyethylene Fibre Reinforced Concrete
This experiment is an investigation into using marble dust as a replacement of cement to some extent in polyethylene fibre-reinforced concrete (PFRC). One of the by-products of the marble industry called marble dust has an eco-friendly alternative that can be used in reducing the usage of cement and make concrete more sustainable. In order to determine the effect of the varying percentages of the marble dust (5%, 10%, and 15%) on the mechanical properties of the PFRC mix such as the compressive strength, tensile strength, and durability, different proportions of the marble dust were added to the PFRC commercially available mix and maintained at a fixed ratio of 6:1. There is an added resistance to crack and increased toughness by adding polyethylene fibre, and the marble dust has an influence on workability and strength development. The outcomes indicate that subbing parts of the marble dust up to 10 percent enhances strength without compromising on the fibre efficiency. The current research instigates the sustainability in construction, waste minimisation through the combination of industrial waste coupled with advanced fibre reinforcing technologies to produce lightweight concrete solutions that are environmentally friendly and durable.
