Abstract
Current practices supporting sustainable building design aim at reducing the expenditure of natural resources, such as raw materials, energy and water, in the production of construction supplies. In the current paper water is replaced by fennel centrifugate (FC) for the realization of cement mortar bricks. After having identified the most suitable cementitious pre-mixed over three potential candidates, the mechanical and physical characteristics of the FC bricks are compared to cement mortar bricks, prepared with regular water, by means of bending, compression at ordinary and high temperatures, imbibition and acoustic tests. From compared results, it is noticed that FC bricks have the same imbibition property, but tensile and compression (ordinary and high temperatures) resistances have about 20% less than the control specimen ones. The acoustic tests revealed a better response of FC bricks to the high frequencies greater than 1600 Hz. However, fennel fibres do not provide a manifest advantage, likely due to the small size of the centrifuged fragments that are not able to enhance the product tensile resistance.
