Concrete with Natural Fibres (Bio Concrete)
The carbon footprint of cement is well known in the civil construction area as one of the most impactful. Concrete is already consolidated as a strong and versatile material for construction. One of the disadvantages of concrete is its high self-weight and carbon footprint. Adding a natural fibre to the concrete mixture reduces the weight due to the lightweight natural fibres and the amount of cement, sand and gravel. Previous research in our research group on the pretreatment of the Miscanthus fibres showed that cement pretreatment improved the strength of concrete, probably due to the increase of bond between the fibres and concrete. The increase in the number of fibres in volume decreases the compressive strength but still has expressive values that can be used for structural elements and increases the tensile strength. This research shows a mixture design for concrete with natural fibres, with a percentage of natural fibres around 20%. The results of the fresh concrete test showed that there was a decrease in the self-weigh for the addition of natural fibres in concrete. Also, the compressive strength decreased with the addition of natural fibres, but on the other hand, the tensile strength increased. The thermal insulation test showed an improvement in the thermal insulation properties with the natural fibres. The fire resistance test proved that the concrete with natural fibres had a good performance.
