Abstract: The present work examined theinfluence on thermal properties of the incorporation of banana pseudo-trunkfibresin a cementitious matrix mortar thatcan be used as rendering or masonry block. The banana pseudo-trunkfibres areextracted, cut and characterized. Then the mortars are made with differentproportions of fibres and characterized in order to identify the parametersinfluencing the characteristics of the material, both in the fresh and hardenedstate. The physical, mechanical and thermal tests carried out have shown anincrease in the porosity and water absorption of the mortar with a decrease inthe density, thus making the mortar lighter. It was also noted a decrease inthe mortar’s flexural and compressive strengths as a function of the percentageof fibres; nevertheless, the values remain within an acceptable range.
